Makes you wonder why the police were so terrified of a guy they already knew couldn’t breathe, eh? That is actually even better evidence to support the murder charge, so thanks. There was also no reason to use excessive force let alone for three minutes after he stopped resisting because you’d already killed him. The fact that Chauvin made very sure that he was dead is just more evidence of malice aforethought. In short, you take your victim as you find him. If you know someome has a breathing problem and then cut off their oxygen, that is first degree murder instead of second or maybe just manslaughter.
One of two things is going to happen. Either Chauvin gets convicted of murder like he deserves or much of the US is going to burn. Either there is justice or self-help. You should get your window plywood and hoses now, just to be safe.
