Thanks for this factual recitation. Given the epic emotions surrounding the case, it's important to put some basic facts on the table.
It seems that almost anybody who watches the full 8+ minute video, knowing none of the context, finds it nauseating. (I haven't been able to find the full video, but I've watched extended excerpts.) It was this visceral response that drove last summer's protests. Later, of course, a much longer video showing the full run-up to the knee-on-neck came out, adding contexts and leading some, although not many, to rethink their initial response. The full toxicology report took a while to come out, too.
I'll be honest: the very first time I saw excerpts of the video, I thought that Floyd, downed, early in the encounter, was grandstanding: shouting "I can't breathe" not because he was actually being choked to death, but because he knew that the encounter was being watched and filmed, and because he was deliberately trying to create emotional leverage--and possibly get Chauvin to release him--by playing on the public's memories of Eric Garner. I thought he was being stagey, even calculated. That was my initial response. It's not a response I wanted to have. But it was my first response. (I haven't gone back to check it against the actual video.)
We know now, since the full video of the encounter and its run-up is out there, that Floyd was saying "I can't breathe" long before Chauvin's knee came near to his neck. He was saying it when he was in the back of the cop car, five minutes earlier. Any reasonable person, knowing that, would take it into account when evaluating exactly what was taking place during the 8:43 knee-on-neck sequence.
What most people saw was a handcuffed black man on the ground, no real threat to the four cops surrounding and on top of him, who had the life choked out of him. It's that tableaux--what people were and are 100% sure they saw: calculated, race-based, and entirely needless murder-by-cop due to asphyxiation--that will be difficult for the defense to dislodge, EVEN IF MOST OF IT ISN'T TRUE. The needlessness of what happened, though, is 100% true.
Glenn Loury, Coleman Hughes, and several other black public intellectuals have questioned whether racism was really operative here. I don't know. In making that case, they invoke Tony Timpa and other whites who have died at the hands of cops. Most of us are familiar with Timpa's name at this point.
Critically important here, I think, are the training that Chauvin received in the use of the neck restraint that he deployed on Floyd. If you're going to hold him criminally liable for Floyd's death, then you need to show that he made one or more grievously bad decisions--actions that were unconscionably out of line with the established protocols in which he'd been instructed. Chauvin kept his knee on Floyd's neck for a while after he stopped struggling. Was that criminal negligence--even if the knee-restraint was justified by policy and properly applied? This is a narrow argument and it won't satisfy many. Certainly many will demand that the ONLY appropriate frame for the entire encounter is a combination of structural racism and individual prejudice (i.e., Chauvin's manifest negative attitudes and behaviors towards black people, if the evidence exists for that.)
Whether or not Chauvin is found guilty, and regardless of what charge he ends up being convicted on (assuming he's convicted), what happened here should, I believe, serve as a wakeup call that there's something very wrong with the way that American policing handled this sort of case. Floyd would almost certainly not be dead if one or more social workers had been quickly deployed to help talk him down from his drug-induced mania and to soften the application of what turned out to be brute force. American cops have a very tough job, but the truth is that there IS a little lack-of-accountability problem, a little too-quick-to-rely-on-violence problem, one that transcends race, and it needs to be addressed in a serious way.
Yes, Floyd was clearly high on fentanyl. Yes, his lungs were two or three times the size the should have been, bloated with liquid. He was in a bad way BEFORE the cops responded. But the way this all played out was straight-up disastrous, in every respect. He didn't need to die. He wouldn't have died if the encounter had been handled differently.
