I see the cops reaction as excessive but not over the top. However, in a moment where they could lose their life I understand the aggressive approach. Hill needs to take accountability for why he was pulled over and why he was pulled from the car. I'm not sure why they put him to the ground but if I were to give anyone the benefit of the doubt without knowing either, I would usually side with the person who hasn't broken the law in this situation, which would be the officers.
That kind of struck me as odd too.
