He didn’t kneel on his neck.
And it doesn’t make you guilty of murder. He controlled his head with a knee block.
It looks terrible, but if he had knelt on him he’d have left injuries.
Even the prosecution say it was positional asphyxia, which is not the knee on the neck. It’s amazing how so many people are reacting to what they see, not what happened.
His tactics were not great, and it does look bad, but he did not do what most people are assuming (his full weight on the neck). If he did do that the prosecution would have used it in their case.
