There's not a lot of worry at the moment
because anyone who's SERIOUS about ccw can still just MOVE where he won't be bothered AT ALL, like Vermont or Alaska, or carry openly in New Mexico, CO, or half a dozen other states. However, when mere possesion of an auto rifle constitutes a felony, everywhere, it will be time to do the Samson thing. Too damned BAD that some that the roof falls on are "innocent".
