Where did this happen? I think if they really wanted to be pricks, they could of been. Did they see you recording them? I think you handled the situation well but I'd advise catching their names and badge numbers without asking. Asking in that type of situation will only piss them off. While its important to put your foot down when flexing your rights, don't forget we don't need more enemies either. I'd rather see cops on our side more than any other person on the street.
