You should consider the fact that Chauvin and Floyd worked together as club bouncers, and had bad blood, according to reports.
Yeah I've considered that. Chauvin may well be a murderer and he may well have used excessive force - within the bounds of procedures but outside the bounds of human ethics. But there is not near proof of either yet. To call him legally a 'murderer' at this point is a serious accusation without all the evidence and speaks of a thought process unencumbered by a requirement to be patient and thorough before throwing 'murder' out there.
He may have had zero intent to murder. And he MAY have. But in this country - 'may this' and 'may that' and 'probably this' and 'sure-likes-like that' doesn't amount to calling someone a murderer. That's kind of a ... lefty ... thing to do.
