Guns are sold by gun companies legally, then to "law abiding citizens"..at some point the transition occurs from legal to illegal (or a lot of gun assaults are done by the legal owners...and the guns never take the illegal step). Either way, cutting them off at the source would have stopped it. I do agree with a lot of you......that with the amount of guns in America already, its too late to do anything.
U.S. citizens own 270 million of the world's 875 million known firearms. Sad, but probably too late.
