In some white liberal circles...the police are almost automatically at fault in confrontations with black criminals, hoodlums, or rioters. When the police arrive on a scene of crime or violence in black communities, whatever they do is likely to be categorized later as either having let the situation get out of hand or as having used excessive force. Any force sufficient to prevent the situation from getting out of hand is almost certain to be called excessive force by white liberals in the media, so that—by definition—the police will have acted badly, no matter what they did or failed to do.
