I know many will have a knee jerk visceral reaction, but some prominent conservatives are joining the liberal and libertarian alliance over these police outrages, and all of us regardless of politics should join together to stop this scourge.
Mark steyn writes for national review and makes the point that not having cameras is a choice, and a calculated one by corrupt law enforcement, and also goes into the history of why American militarized police forces lead to a horrific abuse of power by the police that leads to these murders. Some interesting perspectives and refutation of bad conservative arguments in favor of the police.
Great statistics on the us vs the rest of the world and how terrible our cops are by comparison.
