Something is very off here Sludge, George wasn't resisting arrest. The cops calmly walked him across the road, and then they blocked off the view from the surveillance camera with a police vehicle. This doesn't look like a random act of violence over a dodgy $20 bill, it seems premeditated as every action the police took doesn't make any sense.
