Derek Chauvin is the Minneapolis police officer who killed George Floyd. I don’t have to say “allegedly” killed, because I saw it. Floyd was alive, and then, eight minutes and 46 seconds later, he was not, and the only intervening event that happened was Chauvin’s knee on his neck.Chauvin’s trial started this week, and soon a jury, comprised mainly of white people (of this we can be almost certain), will tell us whether they think killing a Black man should be a crime. In a reasonable world, this trial would be perfunctory. Hell, in a reasonable world, there wouldn’t even be a trial: Chauvin would have accepted some kind of plea deal. That’s what most people do when they are caught on camera killing someone.
