In this article, we discuss the candidacy of one of the more surprising numbers to surface in the course of America’s gun debate: that 2.5 million Americans use a gun defensively against a criminal attacker each year [Kleek and Gertz, 1995]. News items, editorial writers, even Congressional Research Service [Bea, 1994] have mention the 2.5 million defensive gun uses (DGU’s) as established fact. This number is considerably higher than our best estimate of the number of crimes committed each year with a firearm (1.3 million)[U.S. Department of Justice, Bureau of Justice Statistics, 1996]. and has been used as an argument against regulations that would restrict widespread firearms ownership. The implicit notion seems to be that if there are more legitimate uses than criminal uses of guns against people, then widespread gun ownership is a net plus for public safety.
