I'll weigh in... I think the only places where common folks like you and me should not be allowed to carry (I'm excepting OneGuy, Kev, and JM) are detention facilities (to include county jail, state prison, federal prison, etc), courts (same rules as current, metal detectors and deputies/cops), mental/drug treatment facilities, and commercial aircraft. On the airplane thing- this is not for "safety" in terms of stray rounds causing depressurization, as has been said, that's not really a catastrophic/crash incident, I'm more worried about: small space + lots of innocents + armed citizen who is potentially not even remotely trained in CQB = BAD! I'm cool with being on a plane with an armed person, I'm not cool with the fact that one miss is probably going to end the life of an innocent.
