He's locked up because they can lock him up.
I just might be carrying as a result, no matter if he protests to the arresting officers that he was merely excercising his First Amendment Rights of Free Speach (sic) (like muzzies care about free speech, I know).

Even freedom has limits. He threatens to shoot people - he goes to jail. If he hadn't been jailed, he'd then threaten an airline to test to waters. Would you be OK with that also?
