He may have been. But he wasn’t tried for being a dirty cop, and as far as I know he hadn’t been convicted of any of those “complaints”.
He was being tried for the murder of George Floyd, and as far as I’m concerned, it was a show trial to find a whipping boy to Lynch. I thought the law specified for a crime like that, a guilty charge would be “beyond reasonable doubt”.
Whether one thinks that Derek Chauvin was a good or bad cop, is irrelevant in this case, because there are certainly “ reasonable doubt “as the toxicology reports would indicate.
Murder? No. Manslaughter? Yes.
