why the heck is he going into police stations just to trip people up? hes such an idiot. i understand if the cops comes over first and tries to pin something on you and you prove hes wrong, but hes literally walking into their dept. and trying to drum up issues. yes i understand hes not technically doing anything illegal, but hes definitely being a piss off.
"Just to trip people up?" Your question reveals how you think "rights" work (or don't as the case may be).
Bringing awareness to fundamental rights -- whether to disabuse law enforcement or the public at large of widely held misconceptions -- is to help all of us, whether he films in a police station, airport, courthouse, or other public venue.
Perhaps a person with a concealed carry permit shouldn't bring his weapon to [insert place here you don't agree with] because what's the point/that's overkill/that's dangerous/it's unnecessary. Or perhaps he shouldn't be allowed to hold a sign up that says "god bless homeless vets" on a public sidewalk outside of a restaurant because it bothers the patrons?
Rights are rights. Use them or lose them.
