While Standing, before ever going to the ground, Floyd said, I cant breathe.
Thats a very important & inconvenient fact.
and so he was pushed to the ground, penned with a knee to his neck and held there until he died.
No matter how you slice it there is no excuse for what the cops did. They, all four of them, participate in killing the man and it looks like the main perp did it with pleasure.
No excuse for the killing, no excuse for the riots.
They should have gotten him into an ambulence right away but if he died in the ambulance there would still be protests.
Coronary stress attack was happening even then.
