No they didn't. But you keep missing the point. They had him in handcuffs. He was subdued, detained and handcuffed. Why on Earth would anyone think that pinning a man's neck down with one's knee and all his weight while that same man continually said he couldn't breathe all the while he was handcuffed be acceptable? There was no need for it. This cop wanted to take his frustrations out on Floyd because perhaps Floyd didn't comply to his all powerful authority. He ignored Floyd's pleas that he couldn't breathe and it most likely resulted in him committing murder.
