I think that the truth is that it's not a racial issue. It's a thug issue – and thugs will pick any reason that they can for violence. If there were no race differentiation at all, I suspect the same type of crime would have happened for a different reason.
Violence is not caused by race - it's caused by idiots usually who also drink excessively or snort bath salts. This problem is not fixed by an outcry for democratic justice, but through allowing the people who perpetrate these crimes to pass through the system.
