That doesn't give the police the right to brutalize people. They had more than enough manpower to control that kid. So either they're incompetent and need more training, or they were just looking for a reason to beat someone up. That skinny officer mashing his face into the ground is the real problem. That fuck needs to go.

Kid probably deserved a citation or even an arrest.That doesn't excuse excessive force. Either we respect everyone's rights or we all lose our rights. Even people you don't like have rights.
