I think he died in the ambulance but yeah ME said the knee didn't do it. I looked at it again and I'm not sure much weight was on the knee if any really only problem is regardless it just looks bad and is easy for media and the internet to spin as excessive force. Also positional asphyxiation is still a think too even with no weight anywhere on a cuffed suspect that is on their chest they can still possibly pass out and die from the positioning
