I'm sure what eyecue described would happen if someone came into the checkpoint with an improvised explosive device or an improvised incendiary device. Something very plainly and obviously a weapon designed to BE a weapon at that exact moment in time.

But if a fellow rolled in with a firearm that's legal to own in the jurisdiction, and the police clear him, and he's otherwise cleared the security process except for it -- what's the problem? Like I've said, sure, administrative civil fine, but we can't order the police to arrest someone, and no one in Huntsville would try to.

Fireworks are explosives, but we don't ask the police to Goldberg-Spear them to the ground when we discover them, either.
