Without the media and public scrutiny how many of these "mistakes" would just be covered up and nobody would know what goes on?
What you say would be right, IF the media focused as much interest on black cop on black victim and white cop on white victim as they do on white cop on black victim. The latter is the focus in order to push the Lefts agenda. It has nothing to do with trying to hold police accountable or improve police procedures as it does with an agenda.
