I don't know who needs to hear this, but Derek Chauvin himself pleaded guilty in federal court and admitted that he used excessive force.
Whatever the constitutionality or merits of his current effort to reduce or eliminate his federal sentence, that has absolutely nothing to do with his underlying murder conviction. Chauvin was convicted of murder in state court beyond a reasonable doubt, and he admitted his guilt. A subsequent challenge to his sentence does not erase, invalidate, or somehow put that conviction up for debate. Derek Chauvin is, and will remain, a convicted murderer.
And Elon Musk continues to prove, over and over again, that he may be the stupidest smart person I have ever seen in my life.
