Ok, a little backdrop... A 15-year-old girl had been arrested for grand theft auto. Once back at the police station and in a cell, the officer directs her to take off her shoes. She doesn't want to, so she defiantly (and lightly) flings it at him and then calls him a "fat pig". Here's what the cop did next:

The officer claims the "fat pig" insult had nothing to do with the beating, but rather it was due to the fact she committed "felonious assault on an officer." He currently is on paid leave indefinitely.

The first time I saw this video I think I said "Holy crap!" about 10 times. IMO, if that ain't excessive force, I'm not sure what is. I'm no lawyer, but I'd be shocked if she didn't win some kind of lawsuit.
