do you have a source for this claim, or for any of your others? according to the ATF most guns used in crimes are NOT stolen. in this article: http://www.pbs.org/wgbh/pages/frontline/shows/guns/procon/guns.html the ATF agent says that only 10-15% are stolen. the majority are actually bought through straw sales. the next biggest source he says is corrupt FFL holders. he makes the point that if you want a gun and you want it now, its going to take too long to steal it. here is a link to an ATF report (albeit from 1994) detailing sources of guns used in crimes. http://policeissues.com/Sources.pdf in the other studies they reference (table 1) it looks like the top place to get a gun is to borrow it from friends or family. if you have a source showing that most are actually stolen, please share.
