In fairness, did Alvin Crabtree actually break a law? I mean, yeah, firearms are prohibited from being carried through the security checkpoints, but does the jurisdiction there outlaw the carrying of a firearm?

We find guns in Huntsville at the security checkpoint maybe... oh... just to ballpark it, I'll say three or four a year. We're required per our procedures to notify law enforcement who take over everything from there, but the passengers are never arrested (except once, and only because he had an outstanding warrant for his arrest; the arrest itself had nothing to do with the fact that he was carrying a gun in his carry-on). Typically, they return their firearm to their car out in the parking deck, or place it in checked baggage, or give it to someone to take home, and then they roll back in through the checkpoint and continue on their happy way. There's no law here forbidding the simple act of carrying of a firearm.
