Tough love???? Or basic Police brutality? You make the call.
UPDATE: (by Spencerblog) Here's a video of the scene.
It happened at UC Davis. From what I read, the protesters were warned numerous times to move and they refused. They locked arms and actually wanted to be arrested. Pepper spray is often used in riot and crowd control. It allows police to more easily restrain subjects and make arrests. It isn't pretty, but neither are obnoxious protesters when the disobey lawful orders to disperse. In this case, it appears, the protesters were requiring police to use force against them. Going the pepper spray route, is certainly better, less violent, more effective than billyclubs.
