Here’s why you can’t win as a New York cop. Deliverymen from a restaurant serving a black neighborhood kept getting robbed in the same building. The police sent a couple of undercover cops into the building, one dressed as a deliveryman from the restaurant. A black teenage thug, presumably the same one who had been robbing the deliverymen, jumps out and puts a realistic-looking fake gun to the head of the “deliveryman” — whose undercover partner, presuming that his buddy is about to be executed, shoots the thug dead. What happens next? Is there a sigh of relief from the community that this crook, who had a criminal record, will no longer be able to prey on their community? No, the rabble gathers to protest police brutality. Dysfunctional ingrates.
