Don't have any stats. But it might only be what is covered in the news.
Remember the Fullerton incident. And the huge amount of Hispanics that were killed in Anaheim beginning of this year or last year? There was a story in the local paper about some Korean chick that was drunk, and jaywalked across Olympic that was arrested. She was put in the squad car, and as they left, she somehow was able to get the door open, and fell out of a moving patrol car. There was also the incident where the white guy was shot running out of a hostage situation, when he was the hostage a few months back. But got little coverage.
I think police actions happen more than people realize against all races including whiteys. It's just that the news/media only selectively covers those that they think will help their ratings.
