meh.........I give the cameraman low marks on civility. To be sure, the cop made mistakes. The cameraman challenges, the cop thinks it through and backs down. Hectoring the cop with "Am I being detained? Am I being detained? Am I being detained?" while following the cop around, trespassing, and threatening that you're instantly uploading footage to the internet looked like a deliberate effort to prolong a hostile confrontation.
Is it right for an LEO to try to intrude on citizen rights? Of course not. Once you've asserted your rights, though, is it okay to make an LEO's job harder? As a taxpayer and citizen, I say no. I'm sure this will be an unpopular opinion, please be aware that I RDGAF. I'll put on my asbestos undies so y'all can flame away.
