You are correct carry on campus is not allowed. In this state, the full rule I believe is that carry on college campuses is not allowed with out written permission from the head of security or campus police which is (at least at my school) impossible to get. My argument is two fold that appropriate students should be allowed to carry on campus, and that campuses should not bar students from carrying any sort of weapon at all. Students at my school who live in the dorms are not even allowed to have mace let alone an ASP baton or a stun gun. Keeping people helpless seems to be endemic in schools and universities and many other places.
