And how exactly would any sort of pressure to ONE side of the neck obstruct the flow of oxygen? Eg A choke-hold requires BOTH sides to be compressed. No shortage of cases of deaths from around the WORLD, of positional asphyxia where pressure WASN'T applied to the neck. A key aspect in those cases is that the person was still struggling and resisting restraint/arrest, just as Floyd was doing.
How else do you restrict the movement of the upper body and head of somebody who is agitated and likely to injure themselves, while NOT restricting movement of the chest? He did a lot of talking, which involves BREATHING, for somebody who supposedly couldn't breathe.
The procedure in the UK for somebody who is severely agitated and likely to injure themselves whilst in a police vehicle, is to remove them and restrain them, which is just what happened.
Why do they all insist that if they struggle, they then should be released? They certainly are going to do so now.
If he hadn't resisted being removed from his vehicle, being put into the police vehicle, being in the police vehicle, and being restrained outside the police vehicle, then he would be alive. HIS CHOICE.
