Ah, but in this case we can reasonably assume the recorder wanted a confrontation—he didn't learn all his rights accidentally. He is part of the "copwatch" movement which tried s to catch cops breaking the law.
While he was not deliberately Provoking a confrontation, I think he was deliberately inviting one. Possibly he was filming traffic stops to catch cop s using "stop and frisk" illegally (this was mentioned on a related website.)
The guy wasn't trying to start a problem, specifically, but he wasn't there, with the ready knowledge of his rights, by accident. What he was trying to do, as near as I can tell, is just what he did: catch a cop breaking the law.
Considering the number of complaints other people on other websites posted about the offending officer and others in that town, this guy might have gone to that own specifically looking for abuses to capture on film.
I am (pretty) sure he knew he could end up beat up and in jail with no camera, but was young and cocky and decided not to care.
This keeps getting better.
He knew his rights, therefore he wants a confrontation. He's aware and prepared, which makes him a public threat. Only a subversive mother would go out of the way to know their rights and to defend them. Correct?
I like your logic. In that line of thought, let's voluntarily submit to random searches, because if you're honest and have nothing to hide, you should have no problem consenting.
