The video doesn't prove anything. It didn't show everything so we have no idea what happened in between.
It certainly called into question some claims such as everyone was running. And they singled him out because he was black. It appears he was singled out because he was the only one running across the aisle behind the slot machines.
The part that amazes me is he told the cops he had no id and was Michael Bennet of the Seahawks, look it up. They did and looked at a small picture and said, yeah sure and let him go. Anyone else they probably would have said, we'll take you downtown and find out who you are. NFL player privelege?
