@hawk to me the video appears to start with the officer rolling his car into a crowd of people and the people attacking it. Id be curious if there was more people in the road he was rolling thru originally because that's typically how people respond to getting attacked and not at all what a peaceful protest looks like. I've seen this happen three times in Philly now and the results for the police looked something like this.

True fact, if you dont attempt to drive your car thru people it has less of a chance of getting attacked.
