They should rename that, gun violence is someone coming and trying to hurt you or your property. Having locks and child laws has nothing to do with it. And I look up the statistics, and as of 2000, we were ranked 26th for murder, and 33rd for robbery. Turns out those guns in the house do help, we have less of these than over half of the other states. I'll tell you this much, I was carrying guns and hunting by myself long before I turned 16.
This rating system is crap, I think. Having no concealed carry laws means that the law abiding citizens can more easily protect themselves, which means less violence against them.
