The bill also prohibits fleeing to avoid prosecution, custody, or confinement for such an offense.

Additionally, the bill prohibits killing former federal judges, former federal law enforcement officers, or former public safety or judicial officers for a state, local, or tribal agency that receives federal funding.

The bill also prohibits certain assaults on state or local law enforcement officers who work for an agency of a state or the District of Columbia that receives federal funding.  

The bill limits federal court review of challenges to state court convictions for killing a public safety officer or judge.

The bill allows federal, state, and local law enforcement officers to carry firearms if authorized by law.
