Critical Mass bicyclist knocked over by NYPD

I really don't know how that help, cause the video already show us pretty much enough to see that the policeman is doing the assault, and not the cyclist.

You are probably right, I was looking at the video for myself, I stabilized the motion of the camera that recorded it, thought it might be informative to someone.

Although I will say you might be amazed at how much information is lost by saccading eyes.
