                      WEDNESDAY, NOVEMBER 13, 2024

                              United States Senate,
                                Committee on the Judiciary,
                                                    Washington, DC.
    The Committee met, pursuant to notice at 10 a.m., in Room 
226, Dirksen Senate Office Building, Hon. Richard J. Durbin, 
Chair of the Committee, presiding.
    Present: Senators Durbin [presiding], Whitehouse, 
Klobuchar, Blumenthal, Hirono, Booker, Ossoff, and Butler.

          OPENING STATEMENT OF HON. RICHARD J. DURBIN,

           A U.S. SENATOR FROM THE STATE OF ILLINOIS

    Chair Durbin. The Senate Judiciary Committee will come to 
order. Let me say at the outset that the Republican Caucus is 
having a leadership election as we meet here today and will be 
unable for the most part to join us. They've given me 
permission to proceed. We always try to wait until there's 
bipartisan presence, but today it will be extremely difficult, 
and we certainly want to be cooperative with their own 
undertaking.
    I'll make an opening statement and introduce the witnesses, 
and have them each make an opening statement, and then proceed 
to questions. This is our 14th gun violence prevention hearing 
in the last 4 years. Why? Because every Monday morning, I wake 
up to the news of how many people have been shot and killed 
over the weekend, not just in Chicago, but around the United 
States.
    And those who believe that the gun violence is only a 
product of Blue States and Blue cities are just plain wrong. 
Gun violence is across this Nation in every political 
environment that you can imagine, and we should view it as an 
American problem, not as any political problem for any 
particular party.
    I hope to be able to work with the new incoming Chairman of 
the Judiciary Committee, Chuck Grassley. He and I have 
literally been friends for 30 years, and that friendship is 
going to continue. We proved something that our critics didn't 
think was possible. We came up with a sentencing reform bill, 
known as the First Step--First Step Act that was passed and 
signed into law by President Trump, a bipartisan measure, which 
has been viewed as one of the singular reform measures when it 
comes to criminal sentencing. I hope we can follow that same 
model on a bipartisan basis in the new Congress.
    And now to the subject of our hearing. We're examining the 
spread of deadly conversion devices that are increasing the gun 
lethality of gun violence in America. On October the 1st, 2017, 
a gunman opened fire in a crowd of concert goers in Las Vegas, 
killing 58, wounding over 400, traumatizing thousands. The 
extent of the carnage was made possible by a conversion device 
known as a bump stock. In the aftermath, Republicans and 
Democrats agreed that we needed to act swiftly to restrict 
access to go to bump stocks. I just wanted to check. We have a 
video that I want to run, and I wanted--let's if we're ready. 
Let's do it now.
    [Video is shown.]
    Chair Durbin. After the Las Vegas shooting, Republicans and 
Democrats agreed that we needed to act swiftly to restrict 
access to bump stocks. Then President, Donald Trump, directed 
the Department of Justice to issue a rule banning bump stocks, 
and he said, quote, ``We will ban all devices that turn legal 
weapons into illegal machine guns,'' end of quote. Then 
Attorney General, Jeff Sessions, a staunch defender of the 
Second Amendment said it, and I quote, ``This proposed rule is 
a critical step in our effort to reduce the threat of gun 
violence. That's in keeping with the Constitution and laws 
passed by Congress.''
    But earlier this year, the Supreme Court struck down the 
Trump Administration's regulation in a 6-3 decision. The 
Republican-appointed justice has concluded, wrongly in my view, 
that the Trump Administration could not define bump stocks as 
machine guns under the National Firearm Act. Congress should 
respond to this court decision by passing legislation making it 
clear the National Firearms Act covers bump stocks, but Senate 
Republicans have objected to the legislation such as the Bump 
Act that would ban the sale and possession of these deadly 
devices.
    Additionally, we'll hear from witnesses today about 
particularly dangerous device known as the Glock switch because 
it can easily convert or switch a Glock pistol from a semi-
automatic handgun into an automatic machine gun. Glock 
switches, which are banned under Federal law, are cheap, often 
costing less than $20, and they've been increasingly common 
across our country. ATF agents recovered over 5,400 guns with 
conversion devices at crime scenes between 2017 and 2021. A 570 
percent increase from the previous 5-year period.
    This disturbing trend has not slowed in recent years. Last 
month, for example, four people were killed, 17 injured in a 
mass shooting outside of nightclub in Birmingham, Alabama, by 
an individual using a gun with a Glock switch. A survivor of 
the shooting, he said, and I quote, ``It literally looked like 
a war scene. It's scary knowing how close I was to dying.''
    We cannot allow this to continue. I've said it many times 
before, but I don't know how else to say it as I have in the 
past. We have the tools to address the gun violence crisis in 
America, and this is one of them. We must act. Gun 
manufacturers can and should do more to ensure their products 
cannot be converted into illegal machine guns. If manufacturers 
fail to act, Congress should take up legislation to hold these 
companies liable for the foreseeable consequences of their 
actions.
    And I agree with Senator Grassley that Federal agencies 
must increase their efforts to prevent illegal Glock switches 
from being smuggled into the United States by foreign 
companies. I stand ready to work with my colleagues. When 
Senator Graham arrives today, or if he decides that he can't be 
with us, I'll insert his opening statement at this point in the 
record.
    [The prepared statement of Senator Graham appears as a 
submission for the record.]
    Chair Durbin. At this point, I want to introduce the 
witnesses before us. Give them an opportunity to speak after 
they're sworn in. Majority witnesses, the first is Jens Ludwig. 
I hope I pronounced that correctly. Is that right?
    Professor Ludwig. Yes.
    Chair Durbin. Close?
    Professor Ludwig. Yes.
    Chair Durbin. Thank you. The Edwin A. and Betty L. Bergman 
Distinguished Service Professor at the University of Chicago, 
and director of the University of Chicago Crime Lab. He's also 
the co-director of the National Bureau of Economic Research 
Working Group on the economics of crime.
    We're also joined by Esther Sanchez-Gomez. Ms. Sanchez-
Gomez is the litigation director at Giffords Law Center, where 
she also leads the Center's and Make Us Brief Program.
    We also welcome Laura O'Donnell. Thank you for being here, 
Laura. She's a former officer with the Chicago Police 
Department, where she worked for over 24 years, retiring as a 
sergeant in 2021. She managed 22 real time crime centers across 
Chicago. Received the superintendent's award of merit for your 
service. She's also, coincidentally, a survivor of the 2017 
mass shooting at Route 91 Harvest Festival in Las Vegas.
    The two minority witnesses are; Zach Smith. Thank you for 
being here. Senior legal fellow and manager of the Supreme 
Court and Appellate Advocacy Program for the Edwin Meese Center 
for Legal and Judicial Studies of the Heritage Foundation.
    And Ryan Cleckner, former special operations sniper team 
leader with the U.S. Army's 1st Ranger Battalion. Also, an 
attorney who represents Federal firearm licensees and helps 
them to stay compliant with Federal laws and regulations.
    I want to thank all our witnesses and ask them to please 
rise for the administration of the oath.
    [Witnesses are sworn in.]
    Chair Durbin. Thank you. Let the record reflect that all of 
the witness, thank goodness, answered in the affirmative, so 
that we can go forward. And we're going to start with Mr. 
Ludwig.

             STATEMENT OF JENS LUDWIG, EDWIN A. AND

       BETTY L. BERGMAN DISTINGUISHED SERVICE PROFESSOR,

            UNIVERSITY OF CHICAGO, CHICAGO, ILLINOIS

    Professor Ludwig. Good morning. Thanks so much for having 
me. I'm here to talk about a particularly troubling trend that 
we're seeing in the data, which reflects a particularly 
troubling trend that we're seeing on the streets of America.
    In the past several years, we're seeing a rise all across 
the country in the so-called ``shooting fatality rate'' defined 
as the fraction of gunshot victims that wind up dying as a 
result of their wounds. In my hometown Chicago, the fraction of 
shootings that resulted in the victim's death has increased by 
6 percentage points. That's about 50 percent since 2010.
    Research by Janet Lauritsen and Theodore Lentz shows 
something similar is happening all across the United States. 
That's to say this isn't a problem that seems to be unique to 
Chicago, it's not unique to other big cities. It's not unique 
to suburbs, rural areas, Red States, or Blue States. It seems 
to be a problem everywhere.
    When we look at the data to see why this is happening, the 
explanation that's best supported seems to be a large increase 
in the number of rounds fired per shooting. And a significant 
increase--a significant contributor to the increase in the 
number of rounds fired per shooting seems to be the use of 
things like Glock switches and bump stocks, what are sometimes 
called ``machine-gun conversion devices''. This was mentioned 
in the opening statement. These devices modify semi-automatic 
firearms, so they fire automatically functionally equivalent to 
a machine gun. A switch does so for a handgun, a bump stock for 
a rifle.
    In Chicago, the number of firearms recovered that have been 
modified by these devices to fire automatically has increased. 
It was just 9 in 2010. So, it was 9 in 2010, and in 2023, that 
number had increased to, fully, 465. In fact, just last week, 
only a few miles from my house on the South Side of Chicago, a 
Chicago Police officer named Enrique Martinez was carrying out 
a traffic stop in the Chatham neighborhood and was shot and 
killed with a weapon outfitted with one of these switches.
    This proliferation of machine-gun conversion devices 
together with the growing use of high-capacity magazines have 
contributed to this large increase in rounds fired and shooting 
fatality rates. Now, I know that a shooting fatality rate is a 
very abstract way to think about the real-world impact of the 
problem. So, I want to offer a different way to think about the 
public safety implications of this that might be more concrete.
    In the city of Chicago where I live, we've averaged 
something like 2,000 to 3,000 shootings per year since I've 
lived there, in 2007. A 6-percentage point increase in the 
shooting fatality rate since 2010 means that there are 184 more 
murders that happened in 2023 in Chicago than would have 
happened if the shooting fatality rate had been the same.
    One hundred eighty-four murders in Chicago is about one-
third of all the murders that happened in my hometown. That's a 
huge proportional increase in the total number of people killed 
at the hands of someone else as a result of these trends in 
what's happening with firearms.
    So, what might be done? The good news is that the data 
suggests there are multiple, potentially helpful paths forward. 
Of course, Glock switches, as was mentioned by Senator Durbin, 
Glock switches are already illegal under Federal law. Evidence 
to suggest that ban is helpful comes from the 1930 data that 
looks at the 1934 National Firearms Act, which resulted in a 
sharp drop in the number of shootings with machine guns that 
happened in the United States.
    What else could be done? When I talk to my friends who are 
Chicago Police officers, one thing they tell me they're 
increasingly worried about is the possibility that 3D printers 
are being used to create these switches. Whether there are 
legislative ways to make that harder could be one policy the 
data suggests might be worth exploring and has some analogs to 
policies that make it harder, for an instance, for color 
printers to print counterfeit money. There's a large body of 
evidence from social science showing the deterrent effects of 
prosecution and sentencing that suggests the potential value of 
ensuring or potentially enhancing the capacity of local U.S. 
attorney's offices to investigate and prosecute gun crimes 
involving machine gun conversion devices.
    Finally, some of the work that my own research center, the 
University of Chicago Crime Lab, has been doing with different 
government agencies and nonprofits suggest there are different 
social programs that can help prevent young people from picking 
up guns in the first place and using them against other people, 
which seems particularly valuable in a world in which these 
guns are getting more lethal over time.
    Beyond specific possible solutions, the main point I would 
like to emphasize here is that on the long list of things that 
we could be worried about from a public safety perspective, 
this increase in shooting lethality needs to be, in my opinion, 
near the very top. Thank you very much.

submission for the record.]
    Chair Durbin. Thank you, Professor. Mr. Smith.

             STATEMENT OF ZACK SMITH, SENIOR LEGAL

          FELLOW, HERITAGE FOUNDATION, WASHINGTON, DC

    Mr. Smith. Thank you, Chairman Durbin, Ranking Member 
Graham, and distinguished Members of the Committee. I 
appreciate the opportunity to appear before you today.
    My name is Zach Smith, and I currently serve as a senior 
legal fellow in the Meese Center for Legal and Judicial Studies 
of the Heritage Foundation. Before joining Heritage, I served 
for several years as an assistant United States attorney, 
worked in private practice, and clerked for Hon. Emmett R. Cox 
on the U.S. Court of Appeals for the 11th Circuit.
    Fundamentally, today's hearing is focused on the wrong 
solution, aimed at the wrong problem. Contrary to the title of 
today's hearing, there is not a gun violence epidemic in our 
country, but there is a violent crime epidemic. And 
unfortunately, too many elected leaders are refusing to take 
the simple yet necessary steps needed to combat this crime 
epidemic, namely, funding the police and prosecuting criminals.
    But why are elected leaders reluctant to take these common-
sense steps? Unfortunately, too many have bought into the twin 
myths that our criminal justice system is systemically racist, 
which it's not, and that we have a mass incarceration problem, 
or that we lock up too many people in our country. We don't. 
But many have called for policy choices to be made based on 
these faulty assumptions.
    For example, the Brennan Center for Justice has called for 
the prison population to be reduced by 39 percent. The ACLU has 
called for a 50 percent reduction, and one academic has even 
proposed policies that would result in an 85 percent drop in 
the number of people behind bars. These proposals are 
astounding because most people behind bars today are serving 
time in prison for committing violent crimes.
    As I've explained elsewhere, the vast majority of people in 
prison today are serving time in State prisons, and the vast 
majority of State prisoners are there for committing crimes 
such as murder, manslaughter, robbery, aggravated assault, or 
other crimes, including gun-related crimes.
    According to 2022 statistics, those convicted of violent 
crimes make up 62.9 percent of all State prisoners. So, 
reducing the prison population by 50 percent or more 
necessarily means not locking up or releasing from prison 
early, clearly violent criminals. We also know that repeat 
offending is a fact of life with criminals, with many offenders 
going on to re-offend again after leaving prison. And we know 
that aside from the seriousness of someone's crime, nothing 
affects that individual's sentence more than their own criminal 
history. This generally means that when someone repeatedly 
commits more crimes, their subsequent sentences tend to be and 
likely should be harsher.
    In States such as California that have adopted three 
strikes laws, these harsher sentences have increased the prison 
population. But guess what? These laws are effective at 
combating crime. Sadly, many elected officials at the local, 
and State levels, as well as Federal leaders have ignored 
common sense policies and have instead pushed policies that 
hurt public safety.
    One simple action that any Justice Department should pursue 
is an emphasis on felon-in-possession prosecution, Section 922G 
cases as they're colloquially known after the relevant U.S. 
Code Section. This provision makes it illegal for those who 
have been convicted of a felony and those who meet certain 
other requirements too, to possess a firearm.
    Think about it. By definition, if someone is convicted of 
this offense, they already have a felony conviction. They're 
disregarding relevant laws by illegally possessing a firearm. 
And from a resource perspective, these cases tend to be 
straightforward to prosecute and are very effective in 
targeting individuals who are often drivers of violent crime in 
their own communities.
    The Justice Department under the Trump Administration 
prioritized prosecuting these cases, particularly in 
jurisdictions burdened with rogue prosecutors at the local 
level, and hopefully, will prioritize them again. The District 
of Columbia with its unique status also provides insight into 
what happens when local leaders defund the police and 
prosecutors refuse to prosecute crimes. Crime rates, including 
gun crimes increase as a result. Because of the District's 
unique status, subject to Congress's control, reforming these 
problematic policies should be a top priority.
    Finally, the Committee does deserve praise for holding 
today's hearing in at least two regards. First, today's hearing 
focuses, albeit indirectly, on victims. Too often today, 
criminals are treated as victims and the true victims are the 
forgotten component when discussing crime, violence, and 
criminal justice reforms. Second, the Committee deserves praise 
for considering this problem rather than passing the task to 
unelected, unaccountable individuals in administrative 
agencies.
    So, while this Committee's time and efforts would be better 
spent focused on the violent crime epidemic taking place across 
our country, at least the conversation is taking place here 
with the American people's elected representatives.
    I appreciate the Committee's invitation to testify, and I 
welcome the Committee's questions.
    [The prepared statement of Mr. Smith appears as a

    Chair Durbin. Thank you, Mr. Smith. Ms. Sanchez-Gomez.

               STATEMENT OF ESTHER SANCHEZ-GOMEZ,

            LITIGATION DIRECTOR, GIFFORDS LAW CENTER

          TO PREVENT GUN VIOLENCE, BROOKLYN, NEW YORK

    Ms. Sanchez-Gomez. Thank you, Chairman Durbin, and Members 
of the Committee for the opportunity to testify here today.
    My name is Esther Sanchez-Gomez, and I'm the litigation 
director with Gifford's Law Center to prevent gun violence. I'm 
here to talk to you about machine guns, dangerous weapons that 
Congress has taken action on repeatedly, and for which there's 
no constitutional impediment to legislation.
    But I'd like to begin by reflecting on the origins of the 
organization that I represent. Nearly 14 years ago, in my 
hometown, Congresswoman Gabby Giffords was shot in the head 
during a constituent event. On that January morning, in Tucson, 
in 2011, 6 people were killed and 12 others injured. Six years 
later, my fellow panelist, Laura O'Donnell, survived a 
different mass shooting, one that killed 60 people and injured 
500 more. That gunman equipped his firearms with bump stocks.
    When a rifle is modified with a bump stock, the shooter 
only needs to pull the trigger once, and the gun will fire 
continuously so long as the shooter keeps his trigger finger 
stationary and applies forward pressure by leaning into the 
bump stock. The shooting heard at the scene that day was 
accurately described as machine gun fire. Perhaps the biggest 
tragedy is that these shootings aren't just isolated moments in 
our Nation's history, but examples of the sort of preventable 
gun violence that continues to ravage this country.
    In response to the 2017 Las Vegas shooting, and under 
President Trump's direction, the Bureau of Alcohol, Tobacco 
Firearms and Explosives, or ATF, amended its regulations to 
make clear that bump stocks meet the current Federal definition 
of a machine gun. As machine guns, they were subject to the 
Federal ban.
    But this past June, the Supreme Court supplanted its 
firearms expertise for that of the ATF and issued a decision in 
Garland v. Cargill striking down ATFs regulation. Although bump 
stocks are currently regulated by a number of States, they're 
now legal under Federal law.
    Unfortunately, bump stocks aren't the only devices 
equipping shooters with weapons capable of automatic fire. In 
March of this year, 8 high schoolers were shot while waiting at 
a bus stop in Philadelphia. The shooter fired 30 rounds in mere 
seconds. The gunman was able to do so because his Glock handgun 
was equipped with an auto sear.
    Autos sears are small Lego size machine gun conversion 
devices. They can be easily inserted into a firearm, allowing 
it to fire continuously with a single pull of the trigger. 
These devices are also called Switches or Glock switches 
because of their pervasive use on Glock pistols. Unlike bump 
stocks, autos sears are classified as machine guns under 
Federal law and are currently illegal.
    Despite this, autos sears have proliferated significantly 
in recent years with the help of online marketplaces and the 
rise of 3D printing technology. ATF's most recent data shows 
that there was a 570 percent increase, 570 percent increase, in 
auto sears recovered by the agency during the last decade. That 
statistic is sadly borne out in the lived trauma of our 
communities.
    This isn't the first period of American life marred by 
machine gun violence. During the 1920's and 1930's, the country 
was rocked by a gun violence epidemic fueled by Prohibition Era 
organized crime. This violence spurred Congress to action. They 
passed the National Firearms Act in 1934 to regulate automatic 
firearms through registration and taxation.
    As technology changed, our regulation of automatic firearms 
has adapted to keep pace. Since 1934, Congress has acted twice 
to address the violence that the proliferation of machine guns 
and conversion devices causes. First, in 1968, Congress 
expanded the definition of machine gun to include a combination 
of parts that could convert a weapon into a machine gun. Then 
in 1986, Congress completely banned civilian ownership of newly 
manufactured machine guns. Congress has repeatedly taken action 
to regulate machine guns, and address technological advances 
and workarounds.
    The violence we see perpetrated today with bump stocks and 
auto sears can be prevented. Congress has the constitutional 
authority to ban bump stocks, and Congress can grant ATF and 
other Federal law enforcement agencies the resources to 
properly enforce these laws.
    We aren't condemned to live in a society where every 
shooting is a mass shooting. Our schools, places of worship, 
political rallies, concerts, and other gatherings need to be 
protected from gun violence. The Supreme Court has made clear 
that you can act, and the harm occurring in our communities 
compels you to do so.
    Thank you again, Chairman Durbin and Members of the Senate 
Judiciary Committee for the opportunity to testify here today. 
I look forward to answering your questions.
    [The prepared statement of Ms. Sanchez-Gomez appears as a

    Chair Durbin. Thanks, Ms. Sanchez-Gomez. Mr. Cleckner, 
before you begin, let me thank you for serving our country. 
You're welcome today to start your testimony.

                  STATEMENT OF RYAN CLECKNER,

             ATTORNEY, FFLSAFE, FLAGSTAFF, ARIZONA

    Mr. Cleckner. Good morning, Chairman Durbin, and Senators 
of the Committee. I'm Ryan Cleckner. I'm an attorney 
specializing in Federal firearms law, and the Bureau of 
Alcohol, Tobacco, Firearms and Explosives compliance.
    I'm here today as a firearms expert to talk about the legal 
and technical qualities and the differences between bump stocks 
and conversion devices. And I'd like to address them separately 
because they are two very different things.
    Now, a machine gun under the National Firearms Act is a 
firearm that will expel more than one bullet for a single 
operation of the trigger. Bump stocks are not machine guns. 
They are pieces of plastic that could be put onto some firearms 
in place of their standard bump stock that allows someone to 
bump fire the firearm. Now, the term bump fire, that's not 
illegal. Matter of fact, I can bump fire a firearm without a 
bump stock. Bump firing is nothing more than allowing a firearm 
to move rearward under its recoil, and then be pulled back into 
a stationary trigger finger.
    Now, bump stocks do make it easier for some people to bump 
fire, but that's all they are. The fundamental operation of the 
firearm has not been changed. The trigger still needs to be 
manipulated every single time a bullet comes out of the firearm 
just like it was designed and intended.
    Now, putting this into perspective of how big of a problem 
bump stocks by themselves are, the FBI's most recent crime 
stats from last year say that all rifles were used in about 
15,000 incidences of violent crime. Includes all categories of 
violent crime by the FBI. Blunt objects such as hammers were 
used 78,000 times. More than five times--more than all rifles, 
not just rifles, which could have a bump stock or even the 
smaller category of rifles that actually did have a bump stock 
on them.
    The only evidence I can find of a bump stock being used is 
the horrible, horrific 2017 Las Vegas shooting. And what that 
mass murderer did was horrific. I don't think a bump stock 
being on some of his firearms makes a difference enough to try 
to redefine the law about what these items are.
    Now, these conversion devices, or Glock switches, or auto 
sears, they are absolutely machine guns, Okay? Not only the 
National Firearms Act define the firearm, but later laws like 
the Gun Control Act says that any parts that can be used to 
convert a firearm into a machine gun are also a firearm. That's 
what these things are. They're already heavily regulated. 
They're already completely illegal.
    The ATF is already going out of the way to enforce this 
rise that we have with them being used, but the vast majority 
of them that I know of are being imported right now into this 
country, and they're not being stopped as they're being 
imported in this country.
    I think the way that we solve this problem is not to make 
an item more illegal because it's status of being a 
significantly illegal item does nothing, apparently, to stop 
these criminals from using them. I mean, that's the definition 
of a criminal, right? Someone who doesn't obey the law.
    I don't think we can make them more illegal, and if we did, 
I don't think that's going to stop their use. I think what's 
going to stop their use is if we actually prosecute the 
criminals that are using these illegal items, if we keep these 
dangerous people off the streets, and we do maybe the best we 
can to stop the influx of these items across our border.
    I'm also seeing lawsuits right now against firearms 
companies like Glock saying that their design somehow invites 
the use of these devices. I think on its face, that's false. I 
think the reason that there are common with Glocks is because 
Glocks are so common. Sixty percent or more of law enforcement 
across the country uses Glock pistols. The Capitol police I 
passed on the way in this building had Glock pistols on. That's 
why they're so common. I think lawsuits against these 
companies, I think, a misguided focus on trying to make certain 
items more illegal is only going to harm more Americans because 
the real solution is getting the bad people off the streets.
    Thank you. I welcome your questions.
    [The prepared statement of Mr. Cleckner appears as a 
submission for the record.]
    Chair Durbin. Thank you, Mr. Cleckner. Ms. O'Donnell.

             STATEMENT OF LAURA O'DONNELL, RETIRED

          CHICAGO POLICE LIEUTENANT, CHICAGO, ILLINOIS

    Ms. O'Donnell. Good morning, Chairman Durbin, and Committee 
Members. My name is Laura O'Donnell. I'm a retired Chicago 
police lieutenant, and I am one of the over 22,000 survivors of 
the 2017 Route 91 Music Festival in Las Vegas.
    I spent over 24 years serving some of the most violent 
areas of Chicago. I'm accustomed to seeing people on their 
worst day. I've witnessed numerous crime scenes, gunshot 
victims, and even people taking their final breath. Yet nothing 
could have prepared me for October 1st, 2017, the day of the 
deadliest mass shooting in U.S. history.
    We all know what happened that night. However, I'd like you 
to hear it firsthand. My husband, best friend, coworker, and I, 
all Chicago police officers, along with my sister-in-law, who's 
a nurse, traveled to Las Vegas to attend a 3-day country 
concert. On the last night, at 10:05 p.m., the unimaginable and 
indescribable chaos began.
    We heard a pop, pop, pop, at first thinking it was 
fireworks. But then a few seconds later, we heard it again, and 
we knew it was gunfire. My husband pushed us all to the ground, 
and he laid his body over ours as you can hear the bullets 
hitting the ground and screams surrounded us.
    When the shooting momentarily paused, we tried to escape, 
but encountered bottleneck people as more gunfire erupted. We 
were separated from my friends. We dropped to the ground, but 
realized the risk of getting trampled. With the gates being 
locked, people started climbing eight-foot fences, desperate to 
escape.
    As police officers, we're trained to seek cover when under 
gunfire, but the only protection was these metal bleachers. 
Bullets struck them echoing with a ping, ping sound, while the 
smell of burning food filled the air as rounds hit the metal 
grills in the concession stands through a slot of the 
bleachers. I watched my husband move cautiously through the 
venue, urging people to drop everything and go while checking 
on those, lying on the ground amid hundreds of bullets I feared 
he might get hit and die right in front of me.
    When you're in a fight-or-flight response, your body shuts 
down everything that's not essential. Things seem to move in 
slow motion, and it's difficult to process anything. However, I 
remember thinking, ``How can this still be going on? How can 
someone still be firing rounds?'' I also remember trying to 
think of the last things I said to my three children, my twin, 
and my younger sister.
    I had thought I might die, and I had hoped that I told them 
I loved them. When the shooting finally stopped. I have no 
memory of the minutes that followed. As we passed the medical 
tent. I sometimes wonder how chaotic and horrific it must have 
been that my mind blocked it. Yet, other memories are still so 
vivid to this day.
    In the aftermath of the shooting, I was in a daze. My mind 
was moving slow, yet I was hypervigilant. I had trouble 
sleeping, and I struggled to cope with flashbacks. I had 
survivor's guilt. I often wondered, ``Why am I still here? Why 
not me?'' Panic attacks struck me in places like the grocery 
store, and I would leave without buying anything. Leaving home 
alone felt unsafe, especially in crowds. I wanted some control 
and my normal life back. So, I returned to work, but it was 
challenging.
    At the time, I was a coordinator of the first SDSC, 
basically, a real time crime center in one of the most violent 
areas of Chicago, Englewood. One of my duties was to listen to 
audio of gunfire captured by ShotSpotter. As you can probably 
imagine, it was distressing for me, and I needed to take more 
time off of work.
    I sought help through my employee assistance program and 
returned to work. But triggers of the shooting would lead to 
heightened anxiety during scenario-based training and firearm 
qualifications. It was difficult to be in charge of officers 
during major events with large crowds and fireworks. I knew I 
needed more help.
    I began cognitive behavioral therapy with a trauma 
therapist who worked with law enforcement. I joined a weekly 
support group through the Vegas Strong Resiliency Center. I 
also attended an intensive inpatient therapy program at Onsite 
called Triumph Over Tragedy for mass shooting survivors. There, 
I learned coping skills that I still rely on today.
    Seven years later, loud noises, crowded places, outdoor 
concerts just to name a few still activate me. To give you an 
example, a coworker once invited me to a Cubs game. And this is 
how it plays out in my mind. It's an outdoor venue. It's going 
to be crowded. Will I be sitting near an exit? I'll make sure 
to wear gym shoes in case I need to run. This usually leads me 
to decline invites to things I once enjoyed.
    I have my life before Route 91, and I have my life after 
Route 91. I know there must be a purpose to my life and a 
reason I survived. Maybe telling my story here today is one of 
those reasons. The shooter had 23 weapons, including 14 
modified with a bump stock, turning them into fully automatic 
weapons capable of firing over 100 rounds in 10 seconds. That's 
almost 10 times more than without that modification.
    While I was in the venue, he unleashed over 1,000 rounds in 
11 agonizing minutes. Four hundred people were shot, over 800 
were injured. Fifty-eight people died that day. Thirty-six 
women, 22 men. The 3 youngest were only 20 years old. I believe 
that if the shooter did not have a bump stock, more people 
would've escaped. Less people would've been injured, and, of 
course, less would've died.
    Every day, I think of those people who lost their lives. Do 
not let these lives be forgotten. Links to the gunfire are in 
my written testimony. I urge you all to take the time to listen 
to it and take action today to ban these modifications to 
prevent future tragedies. Just last week, Chicago police 
officer, Enrique Martinez, was killed in the line of duty by a 
firearm modified with a switch, making it fully automatic. 
There's no good reason to turn a semi-automatic weapon into a 
machine gun.
    Despite my progress, the scars from October 1st, 2017, 
continue to impact my life. It's a day that I will never 
forget. It will never be forgotten by the 22,000 survivors or 
the family members of those who died. I hope you honor their 
memory as our lives will never be the same. Thank you.
    [The prepared statement of Ms. O'Donnell appears as a 
submission for the record.]
    Chair Durbin. Thank you, not only for your testimony about 
that horrible day in your life, but for your service as a 
police officer in Chicago. It's not an easy assignment, and I 
respect the fact that you did it for over 20 years.
    So, let me ask you this. Do you think most policemen that 
you served with in Chicago or in other places would agree that 
bump stocks have no place to be sold in the United States?
    Ms. O'Donnell. Yes, I believe most police officers would 
agree with me with that.
    Chair Durbin. Mr. Cleckner, you and Mr. Smith seem to zero 
in on the mechanics of mass shooting. When we think of the 
purpose of the Second Amendment for self-defense, sport, and 
hunting, is there a circumstance that you think in the ordinary 
course of life where you need to have that capacity of a 
firearm?
    Mr. Cleckner. Senator Durbin, respectfully, I think you're 
missing a category of why the Second Amendment exists. We wrote 
it shortly after overthrowing a tyrannical government. And I 
think that a bump stock, although has no application for 
hunting and maybe not very much for self-defense, I don't 
believe that banning this item would stop a criminal that's 
already willing to ignore so many other laws.
    Chair Durbin. You just mixed two things up. We talked about 
ending tyranny against the United States, and you talked about 
a criminal in the same breath.
    Mr. Cleckner. Fair.
    Chair Durbin. I don't understand
    Mr. Cleckner. What I'm saying, sir, Senator, is that 
banning an item or making it illegal is not going to prevent a 
criminal from using it. It's already illegal for that shooter 
to be a mass murderer. It's already illegal for them to do many 
other things that the laws did not prevent them from doing.
    Chair Durbin. So, let's stick with your logic. What's the 
point of banning machine guns?
    Mr. Cleckner. Well, machine guns, Senator, are actually 
legal. They're legal for some people to possess. They're just 
extremely regulated, and I believe----
    Chair Durbin. Is that a violation of a constitutional 
right, to regulate that firearm?
    Mr. Cleckner. I think most gun laws are infringements of 
the Second Amendment. Yes, Senator.
    Chair Durbin. Well, I think that's where we're going to 
part company. Because I think most people would agree, even 
firearm owners in my own family, that reasonable regulation is 
not too much to ask if it means saving the life of innocent 
people. When you hear Ms. O'Donnell's portrayal of what 
happened, you described it as a mass murder.
    Mr. Cleckner. Yes.
    Chair Durbin. You described it as horrific.
    Mr. Cleckner. Mm-hmm.
    Chair Durbin. And to think that some regulation might slow 
down the purchase of a device which converts a regular gun into 
an automatic gun, a semi-automatic into automatic gun is an 
unreasonable restriction on the constitutional rights, I think 
that's where we would disagree. Certainly would.
    Ms. Sanchez-Gomez, when it comes to the incidents of mass 
shootings and the proliferation of these devices, what do you 
see lies ahead?
    Ms. Sanchez-Gomez. I think it's incredibly important that 
we regulate these weapons. Machine guns are designed to do one 
thing; kill a lot of people in a very short amount of time. We 
have been regulating machine guns in this country since the 
beginning of the 20th century. We made them unlawful for 
civilian ownership in the 1980's, and we need to extend into 
the future our regulation of machine guns to incorporate 
changes in technology workarounds that the gun industry has 
found for the current State of the law. And there is no 
constitutional impediment for doing so.
    Chair Durbin. I think of the situation just a few years ago 
in Highland Park, Illinois, on the 4th of July, when people 
were assembled for a 4th of July parade. And there were many 
members of law enforcement there who were watching the scene 
and even marching in the parade, and a lone shooter got on the 
roof of a building and fired off, I believe 83 rounds in 60 
seconds, killing seven people and injuring dozens of others.
    It was a young man who had some mental issues before that 
day, and his father decided that a good thing for him to do was 
to buy this type of assault weapon and practice with it in a 
shooting range. It prepared him for that awful day, which 
changed lives in every direction.
    I look at that and think, what is the purpose of his 
ownership of that gun? Is it to stop tyranny according to Mr. 
Cleckner, that's one of the elements that went into the 
Founding Father's calculation of the Second Amendment? What do 
you think about that?
    Ms. Sanchez-Gomez. The Supreme Court has been incredibly 
clear that military-style weapons are not protected by the 
Second Amendment. The Supreme Court has explained that any 
reading of the Second Amendment and of the Court's decisions 
would be startling if it implied that the NFA and its 
regulations of machine guns was unconstitutional.
    Chair Durbin. Professor Ludwig, when you hear Mr. Smith 
describe this as a gun violence problem, or a crime problem and 
not an issue that should involve firearms, I think, I don't 
think he mentioned bump stock in his testimony maybe once at 
the beginning. What is your reaction?
    Professor Ludwig. I think one potentially useful comparison 
is the United States versus the United Kingdom. When you look 
at rates of--so there's a sense in which Mr. Smith is right; 
that there are countries around the world that have lots of 
guns and very low crime rates, and that does not lead to lots 
of gun violence. But there are other countries around the world 
which have similar rates of violent crime to the United States, 
similar numbers of robberies, similar number of assaults, 
countries like the United Kingdom, and they have almost no 
guns.
    And what you see in countries with lots of violent crime 
and no guns is very, very few murders. So, London is a city 
that's three times the size of Chicago. They have fewer murders 
per year than my hometown. The thing that makes violent crimes 
so deadly in the United States is the ready availability of 
guns.
    As you and many in the room know, we have something like 
400 million guns in circulation and 330 million Americans. And 
I think there's lots of evidence from the data that suggests 
that widespread gun availability increases the lethality of the 
violent crime that happens. And I think there's lots of 
evidence to suggest that the availability of these machine gun 
conversion devices further increases the lethality of firearms.
    Chair Durbin. Thanks, Professor. Senator Klobuchar.
    Senator Klobuchar. Very good. Thank you, Chairman, for 
having this very important hearing right now. I'll start with 
you, Professor Ludwig, with the facts. In 2023, police in 
Minneapolis reported that they recovered three times as many 
Glock switches as they did when they first started tracking 
them in 2021. That's only in 2 years. Could you talk, and we've 
seen these same kind of numbers nationally, how does the 
increase proliferation of illegal machine-gun conversion 
devices threaten public safety?
    Professor Ludwig. And so, we're seeing these increases, 
unfortunately, as you note, Senator, in every big city in which 
I've been able to see the data. We're seeing these increases. I 
think the challenge that the growing use of machine-gun 
conversion devices play, maybe combined with the availability 
of high-capacity magazines, means now that more and more people 
are able to fire off larger numbers of rounds over a shorter 
period of time.
    We can see in the data that that's leading to more shots 
fired per shooting incident, more injuries per shooting event, 
and higher lethality rates. Even modest changes in the shooting 
lethality rate winds up leading to very outsized increases in 
the number of people who die as a result of gun violence.
    Senator Klobuchar. Thank you. Ms. Sanchez-Gomez, I 
introduced legislation to require Federal law enforcement to 
coordinate with our State and locals because of what we're 
seeing, in my former job as a prosecutor. And, in fact, one of 
parts of this that we have to look going forward as there are 
efforts to reduce or defund, not the ATF, on the national basis 
coming from some of our Federal colleagues.
    I just want to give one example of ATF working with the St. 
Paul Police Department, Minnesota Bureau of Criminal 
Apprehension, and our U.S. Attorney, was well respected on both 
sides of the aisle, Andy Luger, to investigate and convict a 
teenager who led police down a high-speed chase after firing a 
Glock equipped with a machine-gun conversion device into a 
densely populated neighborhood.
    Can you talk about the importance of funding ATF in 
addition to putting in place better safety guardrails when it 
comes to these devices?
    Ms. Sanchez-Gomez. Thank you, Senator. I think that that's 
exactly right. We need to be giving law enforcement the 
resources that they're asking for. We've been hearing from 
attorneys general across the country, and from ATF, and from 
local law enforcement, that they need more education and more 
resources to understand the scope of the problem and to address 
it at the source.
    Which is, one, importantly, preventing these items from 
being trafficked into the country and preventing them from 
ending up in the hands of people who would use them to do harm. 
Harm, like the harm that occurred in Detroit, Michigan, when 2 
people were killed and 19 others injured at a neighborhood 
block party.
    It's important that we give law enforcement the tools that 
they're asking for. These are already illegal, has been 
mentioned a number of times, and preventing them from ending up 
in our communities is the most important first step in 
combating the problem.
    Senator Klobuchar. Thank you. Ms. O'Donnell, thank you for 
your work and your searing testimony. I believe we need to do 
more to protect our law enforcement officers and support them. 
That's why I lead the COPS Reauthorization Bill and have done a 
lot of work in this area. Could you talk about the challenges 
that law enforcement face when responding to gun violence 
incidences that involve handguns that are illegally modified 
into automatic?
    Ms. O'Donnell. Thank you for the question. What I could say 
is, I think just the last few officers from Chicago who died in 
the line of duty were all from switches. So, you don't have 
time to react. They're just firing too fast. We don't have the 
same weapons firing back. So, it is a big problem. It's 
definitely multiplied in the last few years, as Professor 
Ludwig said, and it's becoming a bigger and bigger problem.
    Senator Klobuchar. Okay. Thank you very much. Thank you.
    Chair Durbin. Senator Hirono.
    Senator Hirono. Thank you, Mr. Chairman. As I sit here, I 
remember one of our earlier hearings on firearms legislation, 
that both the minority witnesses as well, in fact, the entire 
panel consisting of majority and minority witnesses said they 
agreed that this Nation is awash with guns. And Mr. Ludwig, you 
mentioned that we have over 400 million guns and 330 million 
Americans. So, we are awash with guns. I mean, is there anybody 
on this panel who does not think that we are awash with guns in 
this country? Raise your hand if you think otherwise.
    Okay. So, we are awash with guns. And meanwhile, the 
Supreme Court in various decisions, Heller was pretty much an 
astounding decision to me, when suddenly individuals by the 
Second Amendment could own firearms. But Scalia did say that we 
could legislate various kinds of limitations, I suppose that 
you could call it that. And then you fast forward to the Bruen 
decision, where suddenly we're supposed to look to what the 
Founding Fathers thought about in, what, 1791, or some 
astounding timeframes such as that Bruen has led to some 
unintended consequences, by the way.
    So, here we sit talking about--debating about whether or 
not we should put some limits on these kinds of enhanced 
weapons. My staff person just showed me a video of how these--
how fast these enhanced weapons shoot. And I can understand why 
in the Las Vegas situation, so many people were killed. 
Astounding, horrifying. And just listening to the firepower of 
these weapons, one questions whether or not these should be 
illegal at all, and we should not be sitting here talking about 
whether ATF can regulate these firearms or whether we--it is 
somehow left to Congress, ``Hey, good luck with that.''
    So, I hardly know where to start, but maybe it does occur 
to me that there are few, very few instances where Congress has 
rendered companies to be immune. So, gun manufacturers are 
immune from the consequences of people using their products. 
So, Mr. Ludwig, is there a possibility that gun manufacturers--
making them liable, is that an approach that we should 
consider?
    Professor Ludwig. I'm not a lawyer so I wouldn't want to--
thank you for the question, Senator. I'm not a lawyer, so I 
wouldn't want to speak to the legality of that. I think as an 
economist and a social science scientist, I would talk about 
the larger data and evidence about the effects of product 
regulation. And I think we have lots of examples from other 
products like motor vehicles where changing--changing product 
designs have led to massive improvements in safety, whether 
that's through litigation approaches or regulation approaches. 
We can see that when products become safer, products that are 
prone to misuse, that can wind up leading to lives----
    Senator Hirono. Oh, do we not have any lawyers on the 
panel? Okay, so Ms. Sanchez-Gomez----
    Ms. Sanchez-Gomez. Yes, absolutely.
    Senator Hirono [continuing]. You're a lawyer.
    Ms. Sanchez-Gomez. Yes.
    Senator Hirono. Yes. What about holding manufacturers 
liable?
    Ms. Sanchez-Gomez. I think it's a really, really important 
point. I think regulating the gun industry in the way that we 
regulate other industries using litigation, which changes 
incentives for them to act in ways that are responsible to act, 
in ways that prevent the foreseeable harmful consequences of 
their actions, is an incredibly important tool of our civil 
legal system.
    Senator Hirono. Could States hold gun manufacturers liable, 
or is this an area for--or that only the Federal Government can 
act?
    Ms. Sanchez-Gomez. Well, the Federal Government passed--the 
Congress passed a law that gives----
    Senator Hirono. Yes.
    Ms. Sanchez-Gomez [continuing]. The gun industry broad 
immunity. It's not absolute immunity, but it is very broad and 
unprecedented for this industry. And so, the Federal Government 
is the one that needs to act if we want to repeal that 
immunity.
    Senator Hirono. Well, I have the--but the question is, can 
States act? Can States enact legislation that holds gun 
manufacturers liable?
    Ms. Sanchez-Gomez. Yes, absolutely. And States are passing 
laws.
    Senator Hirono. Okay. I think that's one of the ways that 
we can proceed. So, the fact of the matter is, as I watch what 
the Supreme Court is doing, and I have described, by the way, 
this Supreme Court majority as an out of control Supreme Court, 
because I have a growing list of precedents that this Supreme 
Court is tossing out in so many areas of the law, and they're 
not done yet.
    So, I just want to say to this Committee and my wonderful 
Members of the Judiciary Committee that I think we need to pay 
attention to Supreme Court reform, starting with that they 
don't even have any ethics provisions that apply to them. Thank 
you, Mr. Chairman.
    Chair Durbin. That's an issue we've talked about a lot, and 
I hope we'll continue to. Ms. Sanchez-Gomez, how is it that a 
person can buy a 3D printer with instructions from the internet 
to create a Glock switch or a ghost gun? What is that all 
about?
    Ms. Sanchez-Gomez. Glock switches are incredibly small 
devices. They're Lego sized devices that are very simplistic, 
easy to manufacture, and that's also why they're so easy to 
traffic into this country. They're small, they're difficult to 
detect, and that's why a bill like Senator Klobuchar's, which 
would give resources to law enforcement to prevent these from 
being trafficked into the country, to detect, you know, 
marketing that is deceptive to consumers, that implies that 
these are lawful to own. That's why we need to get ahead of 
this problem to stop it from getting into our communities in 
every direction.
    Chair Durbin. Why are pistols equipped with another device, 
which we haven't spoken much about? The stabilizing brace, 
particularly dangerous to the public?
    Ms. Sanchez-Gomez. So, stabilizing braces are not machine 
guns. I want to start off by being clear. When we talk about 
stabilizing braces, we're talking about short-barreled rifles.
    And short-barreled rifles are more dangerous because they 
allow a pistol to be shot from the shoulder, which gives it 
more power and more velocity, and therefore more lethality. But 
still being concealable in the way that a pistol is because 
it's smaller.
    Stabilizing braces were initially designed to allow a 
shooter to stabilize a handgun on the wrist or forearm, but 
what started happening was that the gun industry saw a loophole 
where they began designing stabilizing braces that allowed a 
shooter to shoot from the shoulder, thereby making--converting 
that weapon into a short-barreled rifle, which is regulated 
under the National Firearms Act, and subject to taxation and 
registration.
    Chair Durbin. Mr. Cleckner, what do you think about that?
    Mr. Cleckner. I don't think pistol braces are a problem. I 
don't think they're being used in crimes. I don't think they're 
making crimes worse. I think she brings up a great point about 
the concealability. I think it makes it much harder to conceal 
a pistol when there's a pistol brace on. It makes it much 
larger. And if we're going to talk about increased lethality 
and velocity, a pistol brace does neither of those.
    In fact, a regular rifle has increased velocity and 
lethality, and that has a regular butt stuck on it, which is 
arguably worse than a pistol brace.
    Chair Durbin. So, pistols with braces have been used in 
several mass shootings in Dayton, Ohio, and Boulder, Colorado, 
but you don't think that's a problem?
    Mr. Cleckner. I'm not saying it's a problem that they're 
being used, Senator. I think that, like I said before, I think 
banning them is not going to stop it any more than the banning 
mass murder is going to stop it.
    Chair Durbin. Ms. Gomez, any reaction to that?
    Ms. Sanchez-Gomez. When we talk about firearms, we know 
that access to firearms is a key tool in reducing firearm 
violence, in reducing gun violence. And I think that regulating 
access to dangerous weapons like machine guns, like short-
barreled rifles, is an important tool that we have to reduce 
gun violence in this country.
    Chair Durbin. I see Senator Blumenthal has returned, and 
he's now recognized.
    Senator Blumenthal. Thank you, Senator Durbin. Thank you 
for having this hearing. And you know, I must say, as I talk to 
law enforcement personnel in Connecticut and around the 
country, these kinds of conversion devices, call them Glock 
switches, whatever, are among their biggest worries because 
they're on the firing line. They're the ones who often are 
targets, and they're outmatched when their adversaries, 
criminals have these kinds of devices that can convert semi-
automatics into automatics.
    And even if you say they should be permitted to some 
extent, I'm wondering whether gun manufacturers don't have a 
responsibility to make devices that they sell safer. And I know 
that Senator Hirono kind of raised PLCAA. I have been a 
longtime advocate of repealing PLCAA and enabling litigants who 
have been harmed the opportunity to take action against gun 
manufacturers, just as they do against manufacturers of cars, 
toasters, most consumer products, all consumer products except 
some that are given a specific exemption.
    So, Mr. Ludwig, let me ask you. Are there ways that private 
litigants, if given the right to take action--and I was 
Attorney General of the State of Connecticut for some 20 years, 
but I used to welcome the people I called ``private attorneys 
general'', who indicated the public interest by taking action 
on their own behalf--would gun manufacturers have more of an 
incentive to make their products safer and to avoid the kind of 
advertising that they do now, often appealing to young men as a 
matter of their manhood, if there were the right of individuals 
to take action in our courts?
    Professor Ludwig. Thank you, Senator, for the question. I'm 
an economist. I look at data for a living. We haven't had lots 
of these regulations in the past, so we don't have a lot of 
data to look at what would happen in the case of firearms, 
specifically. But we can look at other consumer products where 
we've changed incentives for manufacturers.
    I mentioned--I mentioned automobiles earlier. There's a 
long list of examples of whether it's regulation or whether 
it's litigation, where we've changed incentives for 
manufacturers to improve the safety of their products. And 
we've seen big improvements in product safety and response.
    Senator Blumenthal. Let me ask other witnesses whether they 
have a view on that question. Ms. Sanchez-Gomez, do you have an 
opinion?
    Ms. Sanchez-Gomez. Thank you, Senator. As a litigator, I 
know that litigation is an incredibly powerful tool in creating 
incentives for, in any industry, and the gun industry in 
particular, to change its behavior, to address problems that it 
knows its products are causing in communities. And I think the 
repeal of PLCAA would be an incredible step in that direction.
    Senator Blumenthal. Ms. O'Donnell.
    Ms. O'Donnell. I'm not a lawyer, so I don't litigate 
anything, but I think, if anything, to get these high-powered 
and fast-firing weapons off the streets is great.
    Senator Blumenthal. Thanks, Mr. Chairman.
    Chair Durbin. Thank you, Senator.
    Senator Whitehouse. Give me a minute to get settled.
    Chair Durbin. Okay. We'll just give my colleague a moment 
to get settled in.
    Senator Whitehouse. So, welcome, Ms. Sanchez-Gomez. What do 
you foresee as the legal perils to bump stock bans at the State 
level? And what legal safeguards do you see, assuming that a 
State like mine, Rhode Island, has a ban on bump stocks? To 
what extent do you think that is a safe safeguard, or is it one 
that can be overruled by Congress for instance?
    Ms. Sanchez-Gomez. I think that there is no constitutional 
impediment to regulating bump stocks. The Supreme Court has 
made incredibly clear that machine guns can be regulated, that 
machine guns are unprotected by the Second Amendment, and bump 
stocks are machine guns in that they approximate rates of fire 
that can only be achieved by fully automatic weapons.
    The Supreme Court in its recent decision, while it said 
that ATF could not bring bump stocks within the Federal 
definition of machine gun, it did invite Congress to act to do 
just that. And I think in doing that, it suggested very 
strongly that Congress could do this constitutionally, and that 
States, of course, could also do this.
    Senator Whitehouse. Well, indulge me in the hypothetical 
that we end up with a Congress that makes bump stock bans 
illegal at the State level----
    Ms. Sanchez-Gomez. At the State level.
    Senator Whitehouse [continuing]. Tries to repeal or 
override State-level bump stock bans. How do you see that 
fitting into the constitutional matrix?
    Ms. Sanchez-Gomez. Well, a State is welcome to repeal a 
bump stock ban if it so chooses, but I think that that would be 
a dangerous choice because these weapons are incredibly 
dangerous. They allow a person to shoot a weapon in a way that 
it increases the lethality of that weapon and ultimately 
sacrifices the accuracy in doing so. These are weapons that are 
very dangerous for people to own. We've been regulating machine 
guns on the Federal level for a very long time, and it's 
precisely because of the sort of features that a bump stock 
gives to a rifle.
    Senator Whitehouse. Do you think Congress has the 
constitutional authority to override local laws against bump 
stocks?
    Ms. Sanchez-Gomez. If Congress were to pass a law 
regulating bump stocks, I think it would be in addition to. I 
think that Congress absolutely has the authority to ban bump 
stocks on the Federal level by bringing bump stocks within the 
Federal definition of machine gun.
    Senator Whitehouse. Yes, I'm clear on that. What I'm 
worried about is that Congress in years ahead will go the 
opposite direction and ban, not bump stocks, but bump stock 
bans.
    Ms. Sanchez-Gomez. That's an interesting question, Senator. 
I'm not sure that I'm prepared to answer exactly that 
particular issue of Federal law.
    Senator Whitehouse. If you don't mind taking that as a 
question for the record and responding, I'd be gratified.
    Ms. Sanchez-Gomez. I'd be very happy to. Thank you.
    Senator Whitehouse. Thanks very much. Thank you, Chairman.
    Chair Durbin. Thank you to the panel for your testimony. 
The record will be open for 1 week for submission of materials, 
and if there are any further questions from the colleagues who 
were precluded from attending today.
    This is an issue of life and death and should be viewed as 
such. Just not a political debate. And the question we have 
before us is whether this Congress, whoever controls it, is 
going to try to make America safer. I certainly hope we do. We 
owe it to the people of this country.
    So, thank you-all for coming today. And with that, the 
hearing stands adjourned.
    [Whereupon, at 11:04 a.m., the hearing was adjourned.]
