"(1) the rights of citizens—

"(A) to keep and bear arms under the second amendment to the United States Constitution;

"(B) to security against illegal and unreasonable searches and seizures under the fourth amendment;

"(C) against uncompensated taking of property, double jeopardy, and assurance of due process of law under the fifth amendment; and

"(D) against unconstitutional exercise of authority under the ninth and tenth amendments;

require additional legislation to correct existing firearms statutes and enforcement policies; and

"(2) additional legislation is required to reaffirm the intent of the Congress, as expressed in section 101 of the Gun Control Act of 1968 [section 101 of Pub. L. 90–618, set out below], that 'it is not the purpose of this title to place any undue or unnecessary Federal restrictions or burdens on law-abiding citizens with respect to the acquisition, possession, or use of firearms appropriate to the purpose of hunting, trapshooting, target shooting, personal protection, or any other lawful activity, and that this title is not intended to discourage or eliminate the private ownership or use of firearms by law-abiding citizens for lawful purposes.'."

Pub. L. 90–618, title I, §101, Oct. 22, 1968, 82 Stat. 1213, provided that: "The Congress hereby declares that the purposes of this title [amending this chapter] is to provide support to Federal, State, and local law enforcement officials in their fight against crime and violence, and it is not the purpose of this title to place any undue or unnecessary Federal restrictions or burdens on law-abiding citizens with respect to the acquisition, possession, or use of firearms appropriate to the purpose of hunting, trapshooting, target shooting, personal protection, or any other lawful activity, and that this title is not intended to discourage or eliminate the private ownership or use of firearms by law-abiding citizens for lawful purposes, or provide for the imposition by Federal regulations of any procedures or requirements other than those reasonably necessary to implement and effectuate the provisions of this title."

Pub. L. 90–351, title IV, §901, June 19, 1968, 82 Stat. 225, provided that:

"(a) The Congress hereby finds and declares—

"(1) that there is a widespread traffic in firearms moving in or otherwise affecting interstate or foreign commerce, and that the existing Federal controls over such traffic do not adequately enable the States to control this traffic within their own borders through the exercise of their police power;

"(2) that the ease with which any person can acquire firearms other than a rifle or shotgun (including criminals, juveniles without the knowledge or consent of their parents or guardians, narcotics addicts, mental defectives, armed groups who would supplant the functions of duly constituted public authorities, and others whose possession of such weapon is similarly contrary to the public interest) is a significant factor in the prevalence of lawlessness and violent crime in the United States;

"(3) that only through adequate Federal control over interstate and foreign commerce in these weapons, and over all persons engaging in the businesses of importing, manufacturing, or dealing in them, can this grave problem be properly dealt with, and effective State and local regulation of this traffic be made possible;

"(4) that the acquisition on a mail-order basis of firearms other than a rifle or shotgun by nonlicensed individuals, from a place other than their State of residence, has materially tended to thwart the effectiveness of State laws and regulations, and local ordinances;

"(5) that the sale or other disposition of concealable weapons by importers, manufacturers, and dealers holding Federal licenses, to nonresidents of the State in which the licensees' places of business are located, has tended to make ineffective the laws, regulations, and ordinances in the several States and local jurisdictions regarding such firearms;

"(6) that there is a casual relationship between the easy availability of firearms other than a rifle or shotgun and juvenile and youthful criminal behavior, and that such firearms have been widely sold by federally licensed importers and dealers to emotionally immature, or thrill-bent juveniles and minors prone to criminal behavior;

"(7) that the United States has become the dumping ground of the castoff surplus military weapons of other nations, and that such weapons, and the large volume of relatively inexpensive pistols and revolvers (largely worthless for sporting purposes), imported into the United States in recent years, has contributed greatly to lawlessness and to the Nation's law enforcement problems;

"(8) that the lack of adequate Federal control over interstate and foreign commerce in highly destructive weapons (such as bazookas, mortars, antitank guns, and so forth, and destructive devices such as explosive or incendiary grenades, bombs, missiles, and so forth) has allowed such weapons and devices to fall into the hands of lawless persons, including armed groups who would supplant lawful authority, thus creating a problem of national concern;

"(9) that the existing licensing system under the Federal Firearms Act [former sections 901 to 910 of Title 15, Commerce and Trade] does not provide adequate license fees or proper standards for the granting or denial of licenses, and that this has led to licenses being issued to persons not reasonably entitled thereto, thus distorting the purposes of the licensing system.

"(b) The Congress further hereby declares that the purpose of this title [enacting this chapter and repealing sections 901 to 910 of Title 15, Commerce and Trade] is to cope with the conditions referred to in the foregoing subsection, and that it is not the purpose of this title [enacting this chapter and repealing sections 901 to 910 of Title 15] to place any undue or unnecessary Federal restrictions or burdens on law-abiding citizens with respect to the acquisition, possession, or use of firearms appropriate to the purpose of hunting, trap shooting, target shooting, personal protection, or any other lawful activity, and that this title [enacting this chapter and repealing sections 901 to 910 of Title 15] is not intended to discourage or eliminate the private ownership or use of firearms by law-abiding citizens for lawful purposes, or provide for the imposition by Federal regulations of any procedures or requirements other than those reasonably necessary to implement and effectuate the provisions of this title [enacting this chapter and repealing sections 901 to 910 of Title 15]."
