I believe they went that route bc of him being told not to roll his window back up and he refused to follow their order, that alone is breaking the law. Clearly that is a major safety issue for the officer.
However, that’s only what I was told by people that watched the footage of the body cam. I have not.
More than likely both parties are at fault. If he wasn’t driving like an idiot he isn’t in that situation, if he obeyed it doesn’t escalate, if he wasn’t putting everyone’s life in danger there’s likely not as much animosity, and then the officers I guess could have showed more self control in the situation.
