With the remarkable disrespect shown to New York’s Mayor de Blasio by the NYPD recently, it’s instructive to go back and reread what de Blasio said that sent New York’s finest into such paroxysms of rage. Via Michael Tomasky:

This is profoundly personal for me. I was at the White House the other day, and the president of the United States turned to me, and he met Dante a few months ago, and he said that Dante reminded him of what he looked like as a teenager. And he said, I know you see this crisis through a very personal lens. I said to him I did. Because Chirlane and I have had to talk to Dante for years, about the dangers he may face. A good young man, a law-abiding young man, who would never think to do anything wrong, and yet, because of a history that still hangs over us, the dangers he may face—we’ve had to literally train him, as families have all over this city for decades, in how to take special care in any encounter he has with the police officers who are there to protect him.

That’s it, folks; the cause of all this anger and disrespect.
