Fullerton, CA cops beat Kelly Thomas, a schizophrenic homeless man, to death last summer (July 2011), and the incident is under investigation. So far the story has garnered only local news attention. The main reason for the disinterest is that it has no value for WAGGING the RACE WAR.
There’s a video of the proceedings at the above link. Most are likely to conclude that the cops used excessive force. There will be no demonstrations nor riots in response to this event.
