How 'bout civilian nukes, chem and bio? I'm willing to take a chance on HE, but NBC is a little long lasting in its effects...
No kidding, NBC is nasty. But, my post was academic; I don't think we really have to worry about the SCOTUS tossing out NBC regulations on 2nd amendment grounds any time soon. Even if they did rule that we needed a constitutional amendment to regulate WMD, I bet we would witness the fastest ratification of a constitutional amendment in history. It might even be ratified before SCOTUS can even grant cert. Besides, no matter what the courts do, Jack Bauer will lay a 24 hour smack-down on any would be terrorist.
