We’ve commented how the police kept the media far away during the crackdown in Zuccotti Park last night so as to prevent capture of images of the efforts to clear the square. There were reports at the time via the live feed of protestors being tear gassed and dragged away by their arms and legs, and later of the use of pepper spray and batons.
This video was from this morning, when the police were keeping protestors out of the park, an illegal violation of a court injunction. The protestors show a copy of the court order and are (predictably) denied access to the park. The woman was punched at around 1:45; the footage does not show the actual blow, but you can pretty clearly infer from her suddenly being on the ground in obvious pain what happened.
If this is what you see, imagine what happened last night, with no cameras and videos to constrain police aggression.
