I don't know if there's any point in commenting. First, it's a grave issue that the officer's cam was turned off. If it happened by accident, in the tussle, that's one thing. If it was on intentionally that's another.

Re: "capture" I'm not sure it's that so much. Cops hate, hate losing control of situations, or seeming to. Notice how Lyoya emerges from the car, despite being told to stay in. That's an escalation. I don't think language or culture explains it, either. Then he seems to walk away. Again, I don't think the issue is capture as much it is the officer seeming to lose control of the encounter.

Police are trained that, above all, they must maintain control of any encounter. Taking away that control, or appearing to, is a guaranteed escalator.

I've seen that happen, experienced it. My wife & I are just an old white couple. But after an argument with a shady hotelier in Kittery Maine, police were called. We're in our car. My wife in back. The cop's laughing, kind of on our side, because the motel guy wouldn't give us a room, despite a reservation, or refund our money. He just wanted us gone. My wife was upset after a long, long drive. Suddenly she got out of the car & went to sit on a curb. Cop's attitude went from day to night. He was pissed. I thought we were going to be arrested suddenly.

You just can't get out of your vehicle then stroll off when the police stop you. That doesn't mean it's right to use deadly force. Of course not. I don't know if we'll ever get to the bottom of this, thanks to the magic recorder off button. But people walking away from police interviews is like a rabbit running past a pack of dogs.
