The Right to Keep and Bear Arms REPORT of the SUBCOMMITTEE ON THE CONSTITUTION of the UNITED STATES SENATE NINETY-SEVENTH CONGRESS Second Session February 1982 Printed for the use of the Committee on the Judiciary U.S. GOVERNMENT PRINTING OFFICE WASHINGTON: 1982
The Subcommittee received evidence that the BATF has primarily devoted its firearms enforcement efforts to the apprehension, upon technical malum prohibitum charges, of individuals who lack all criminal intent and knowledge. Agents anxious to generate an impressive arrest and gun confiscation quota have repeatedly enticed gun collectors into making a small number of sales — often as few as four — from their personal collections. Although each of the sales was completely legal under state and federal law, the agents then charged the collector with having "engaged in the business" of dealing in guns without the required license. Since existing law permits a felony conviction upon these charges even where the individual has no criminal knowledge or intent numerous collectors have been ruined by a felony record carrying a potential sentence of five years in federal prison. Even in cases where the collectors secured acquittal, or grand juries failed to indict, or prosecutors refused to file criminal charges, agents of the Bureau have generally confiscated the entire collection of the potential defendant upon the ground that he intended to use it in that violation of the law. In several cases, the agents have refused to return the collection even after acquittal by jury.
