My thoughts: The gentleman that made the video obviously went out to "make a point", and tried to provoke the officer into doing something improper. Open carry is obviously legal at that location, otherwise the stop would have gone quite differently. That being said, IMO he did nothing to improve the relationship between OC proponents and the police with his adversarial attitude. I get the whole open carry thing, even though I choose not to do so, but being rude and adversarial with a police officer that is merely trying to have a conversation with you is not accomplishing anything except possibly souring that officer's opinion of OCers in general.
