Interesting. Based on the video, I tend to side with the officer. Whether you think he's right or not is irrelevant, he IS the law and you're under obligation to follow his instructions. If he's done something wrong or out of line, you can file a complaint with his department at a later time.
Earlier this year, we had a deputy sheriff on solo patrol in a rural area of Sacramento County. He made a stop in the middle of the night on a van without license plates, and nobody knows what happened after that. He didn't respond to a wellness check call shortly after his stop, and when other deputies arrived on scene, he was laying next to his car, dead from a shot to the head with his own sidearm. They've never found deputy Jeff Mitchell's murderer, and have no leads that have been made public. His patrol car did not have a video camera onboard.
In another incident earlier this year, one I started a thread about here on MM, a California Game Warden cited a druggie where he was living, for a misdemeanor violation and subsequently found out that the tweaker had an outstanding warrant from Hawai'i for distribution of meth. He, much like this fellow, refused to follow the game warden's orders and refused to surrender for arrest. Instead, he walked into his trailer and came out with a shotgun leveled at the warden, who promptly shot him to death, justifiably so. Perhaps, if the warden had more assertive and tazed the druggie when he refused to follow orders and stop before walking into his trailer, he'd have been able to arrest him without having to defend his own life.
I can't imagine why anyone would fail to understand that law enforcement officers are to be obeyed at the scene of a stop, and you can deal with any disagreement or dispute later. In this case, the officer seems to have acted properly, IMO.
