UCLA Police - America's finest caught on video

Someone kindly posted this video (recorded on a mobile phone) of the events that unfolded as a student who had forgotten his ID card was asked to leave the library in the Powell Building at the University of California, Los Angeles...

Why would this be of interest, I hear you ask? I, too, would have imagined it would probably have been either "Well, you'd better go fetch it then!" or "Well, I know your face, don't forget next time, that's all I'm sayin'" (depending on how the officer was feeling at the time)...what actually happened simply defies belief...

We hereby redefine "disproportionate force"...
