Number: RL32585 Title: Semiautomatic Assault Weapons Ban Authors: William J. Krouse, Domestic Social Policy Division Abstract: This report focuses on the use and interpretation of firearms trace data produced by the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF). Ban supporters have presented some of these trace data to support extending the ban, making it permanent, and perhaps strengthening it. Ban opponents counter that there are serious limitations regarding these trace data. Meanwhile, researchers continue to debate the proper use and interpretation of these data.
