Allowing concealed weapons on college campuses is a silly, and dangerous, idea

College, we like to think, is a time of intellectual inquiry. But it is also, as anyone who has spent any time on a campus knows, a time of boundary-testing, experimentation and alcohol-fueled parties. Not exactly the kind of place where it makes sense to let folks wander around carrying hidden...
