Nope, I agree with you.
I mean, I don't personally have any statistics with regards to the percentage, but I think he was fairly professional about it. I don't know what she was being arrested for. If it was a victimless crime ,the officers are wrong, period. I don't know for sure if she was actually trying to slip out of the cuffs or not, and if not, I don't know why the officer believed that she was. And if its a victimless crime, it might have been pragmatically unwise, but not a violation of the NAP, for her to resist. On the other hand, obviously if there actually was a victim, the cop would have had a moral right to arrest her. And, as you said, he actually talked to the people and he didn't try to prevent them from taking a video. At the very least, I don't think he was deliberately abusing power here. And honestly, I think the people who were talking to him were a little rude. I could understand that if they KNEW it was a BS arrest, but frankly, they didn't know, and they weren't really letting the cop try to explain, so I can understand him getting a little frustrated.
