I'll get back to these later (maybe after finals...):
1. Instead of stepping on the Second Amendment right to bear arms, why not step on the First Amendment's freedom of the press and forbid stories about mass or serial murders (seeing as apparently the Constitution is a Create-Your-Own-Adventure document).
2. Is a university a place of public accommodation? If so, can I sue my school if a gunman shoots up William & Mary (God forbid)? Can I seek equitable relief to force them to hire and station trained security guards around the campus or, alternatively, to disallow those holding Concealed Handgun Permits from being subject to "academic discipline" should they be found to have a firearm or ammunition on campus?
