Interesting debate. The school I go to (see my avatar) is gearing up to allow guns on campus (not in the buildings, though.)

I’m not a gun owner, but I have no problem with it if they do go through with it. I doubt many people really will carry, but if some of them do (I suspect a couple of my friends would like to) I doubt it will make much impact. People that would start a school shooting would have done so regardless of the law, I think that’s been pretty well proven. What I would like is if it was legal to carry a knife on campus (the size I’m used to carrying while hiking.) That would make me feel safer.
