In my opinion the high amount of gun violence stems from the fact that there's over a quarter of a billion guns in country. So the "criminals" who are going to do bad things to you are armed to the teeth with guns that they either bought legally, or snagged from under your mattress/"blackmarket",etc. Legal registered owners of guns get robbed. It's not hard to imagine that some gun owners might not heroically blow away the "evil-doers" when they get robbed, and inadvertently end up supplying guns to criminals.
