Can you board a flight in the US carrying a weapon?
Argue your Second Amendment rights then.
Believe it or not, there was a time in this country where you could. Planes didn't get hijacked back then. And grandmothers and Medal-of-Honor recepients weren's subjected to warantless searches by Stasi-wannabees.
Argue your Second Amendment rights then.
You'd probably be doing so from a jail cell unless you were a "party member in exceptionally good standing".
Since you'd be arrested by an agent of the state, sitting in a jail owned by state, and so one, one might conclude that the state is infringing upon your 2nd amendment Rights.
After your 50 previous posts on this thread about how the "2nd amendment only applies to gov't infringements", I suspect that we will discover that you don't give a rat's behind about those infrigements either. So I don't expect you to have any problem with the state banning citizens from flying armed.
I've come to the conclusion that you simply don't like "average citizens" carrying guns and you will do anything in your power to harass them and make life difficult for them.
