Cops are not our betters, and the action of Philadelphia criminals are irrelevant to innocent people.
You are right, they are not out betters. As for the actions of Philadelphia criminals being irrelevant to innocent people- The actions of any of us, cops included, hold relevance in how the rest of us operate. Whether the police officer is walking into a donut shop to check on recent burglaries or pulling over someone for speeding, he/she is not blessed with the gift of immediately knowing who is a criminal/natural born killer and who is an innocent/average joe.
