As satisfying as it might be to convict the other three, I would bet on their defense. Kneeling on someone's neck while maybe not procedure is not automatically lethal. The other three cops had no way to know the excessive pressure being applied by Chauvin.
.
I think extreme negligence can be agreed upon between the city and the police union in order for the dismissals to stand. Unfortunately for these three, the police union doesn't want to be on their side in this ugly matter.
What I would argue as counsel too. They DID call an ambulance when he passed out. Not sure why Chauvin is still kneeling on the poor dead guy - unless Chauvin really is a complete asshole.
WaPo narrative stated that C was on the BACK of F's neck - away from the windpipe and other vital shit like the carotid artery and vagus nerve. But angles and continuity aren't great.
F says "I can't breathe at one point." OTOH coroner's partial says no death by strangulation or asphyia. Assuming the report has not been tampered w or faked - and as mentioned, I think the authorities would like to flush C away at this point. Plus, the Minne DA's office has actually carried forward police violence prosecutions in a reasonably diligent manner.
I wonder if you're mis characterizing the Police Assoc though. Those assholes will defend fucking anything!!!
