Excerpt from The New Yorker:
One thing that stands out about recent police killings is how few of the shooters are in jail; juries and grand juries have generally accepted their explanations and allowed them to go free. The moral logic of Blue Lives Matter is that we send the police into places where we are too scared to go—who are we, safe in our distance, to second-guess their judgment that a situation has grown too frightening to control? The argument has some power because the dangers, for cops, are real. The possibility of violence is overwhelming. In Baltimore last fall, I watched a veteran cop (African-American, a professor’s son) conduct a training session in which he described his state of mind when he was dropped, as a rookie, into a violent section of West Baltimore. He said he was terrified, because he was sure that surrounding him, undetectable to him, were people capable of killing someone, and because he knew he had a gun and that he was capable of killing someone, too.
