Firearms on College Campuses

I think that students having firearms on college campuses is a bad idea. Your not going to prevent people using the firearms with more firearms. It could lead to gang shootouts or maybe a spontainious shooting. What i mean by that is, that someone may not have any intention of doing anything stupid but with the gun there, they could make a stupid decision in the heat of the moment. College professers having a weapon though would not be a bad practice because they can be trusted and there is some form of defense against a gunman if there were to be one.
