Not innocent for sure of a crime. I do not agree that he killed Floyd. The drugs did that, but Derek Chauvin was guilty of being a prick police officer and showing his 'power' side. He was showing just how 'tough' he could be to the crowd and even his fellow officers. I disagree with the murder charges, but his manslaughter conviction may be valid because Floyd died while under his control.
End of the day, drugs killed, Floyd, and, Chauvin, missed the opportunity to save Floyd's life.
