He had a lethal amount of fentanyl in his system. Autopsy showed no soft tissue injuries. Chauvin didn't have much weight on his neck, Floyd was able to be heard without much effort. They should have rendered aid when he lost consciousness. They would have given him life saving narcan had Floyd not lied about his drug use. The jury got this one very wrong.
Even if you believe that Floyd was murdered it does nothing to support the notion that racist cops roam the hood looking for unarmed black men to murder.
