"Congress has debated the efficacy and constitutionality of federal regulation of firearms and ammunition, with strong advocates arguing for and against greater gun control. The tragic shootings in Tucson, AZ, on January 8, 2011, in which six people were killed and 13 wounded, including Representative Gabrielle Giffords, could prompt the 112th Congress to examine issues related to the shooter's mental illness and drug use and his use of large capacity ammunition feeding devices (LCAFDs) (see H.R. 308 and S. 32), as well as a proposal to ban firearms within the proximity of certain high-level federal officials (see H.R. 496). This report provides basic firearms-related statistics, an overview of federal firearms law, and a summary of legislative action in the 111th Congress and selected legislative action in the 110th Congress that involved issues revisited in the 111th Congress. The report concludes with a discussion of other salient issues that have generated significant congressional interest in the past, including the 1994-2004 LCAFD ban."
