In the event you haven’t yet watched the video that was released by an attorney for one of the University of Maryland students who claims he was beaten by Prince George’s County police officers last month, take a minute to do so now. You’ll recall that 27 people were arrested on March 3 in the wake of post-game celebrations in College Park — celebrations that by all accounts got out of hand. But this video is really quite damning, and has in fact already led to the suspension of at least one and a criminal investigation against a total of three sworn officers.

The video shows John McKenna, 21, appearing to be in the middle of a celebratory dance on the sidewalk. He stops as he nears an officer on horseback, then backs up a bit, then two officers in riot gear run at him, slam him against a wall and start beating him with batons. A third officer then joins in the beating. McKenna does not appear to fight back at all.
