If the toxicology screen comes up 100% clean this autopsy shows that what happened wasn't murder or anything close to murder.It was reckless...it was negligent...it was unnecessary...it was a violation of Department Policy...and it's deserving of at least some time (and,perhaps,a good chunk of time) in prison.
Nothing more...nothing less.
If the toxicology screen isn't 100% clean (my guess is that it isn't) subtract some prison time from what the cop might have gotten if it had been clean.
I suspect and I have no proof of it but that he perhaps swallowed some evidence when he first saw the cops approaching his car....remember, there were two other people in the car with George...what do they have to say?
remember Floyd was complaining of his stomach hurting?
