And here is the important point and the point I have been trying to make with this excessively wordy post. The most important safety valve to prevent violence like we saw in Dallas last night is the belief that when officers do go off the rails, the legal system will punish them accordingly. If minority communities (and everyone else, for that matter) believed that, resort to reprisal killings would be either non existent or far less frequent.
But they don’t, and there’s good reason for that. And that is because a huge, overwhelming segment of America does not really give a damn what cops do in the course of maintaining order because they assume (probably correctly) that abuse at the hands of police will never happen to them. As long as the cops keep people away from my door, they have my blessing handling “the thugs” in whatever way they see fit.
