As a member of Occupy D.C. hinted at yesterday’s rally outside Metropolitan Police Department headquarters, the group posted video taken last Friday night of what appears to be an MPD officer wrapping his hand around the neck of a protester while Occupy D.C. was at the Walter E. Washington Convention Center to protest a meeting of the political-action group Americans for Prosperity.

In the video, which is somewhat blurry, an officer appears to wrap one hand around the Occupy member’s neck and the other on her shoulder and lower her to the floor, while at least one onlooker screams, “Hey, what are you doing?”

Occupy D.C. identified the protester wrestled to the ground as Georgia Pearce, who later that evening was one of four members struck by cars outside the convention center.

At the rally yesterday at the MPD headquarters, Arsenio Rodriguez announced he had video of a cop pushing Pearce to the ground, though he says the clip posted this morning was shot by someone else.
