College kids and guns are a bad mix, as I've noted before, but aside from that...just who do they think they are defending themselves against? What kind of safety issues do they think exist?
When I was growing up, I "knew" the city was a scary place where crime happened. I never thought about it anywhere else. Not saying my characterization of the city was necessarily correct at the time, just that the entire point of living in the burbs was that it was safe. That characterization might not have been correct, either, but I don't remember people worrying about "protecting themselves" all the time. Where did this come from?
