I may stand corrected, but i am fairly certain no legal NFA weapoan has ever been used in a crime. Not one, ever.
Bad thing to bring up......could be argued as a reason for the jackboots to register everything.
MG’s are the 3rd rail of the 2nd amendment....shouldn’t be. Just are. Our side even argued as such in the Heller case even though the bastards in the 30’s made the NFA of 34 a revenue law just to avoid the militia question. $200 in 1934 would be about $10k today. An effective ban.
They are what we should own if GI Joe has them.
Cop in Dayton used a CIII M-16 in the late 80’s to whack his girlfriend. That is only criminal use of a legal NFA I know of.
I believe there is one ( and one “possible”)instance. It involved a Mac11 in .380, and the shooter was a police officer who murdered a police informant. This link has the details. http://www.guncite.com/gun_control_gcfullau.html
