A competent cop wouldn't have kneeled on Floyd's neck as long as he did. True, that move is a regulation move, but so is using a Billy club and fire arm...and yet police use those tools without setting off a national riot. (And of course the rioters are to blame for the property destruction, just like Adam and Eve bit the apple.)
A competent cop would have apprehended the purp without an audience of a dozen. The policeman would have cuffed Floyd and driven away. And if Floyd died of a drug OD in the patrol car, we wouldn't be here.
Floyd isn't a Saint. But neither is the cop.
I am assuming you are a large metro cop and can speak cogently on what does and does not make a competent cop in a major metro area. You are fully trained in crowd control and arrest procedures. Because if none of that is true you are just talking out your backside. You are repeating one side of a complex story.
Have you ever tried to restrain someone that does not want to be restrained? You make it sound like one simple BJJ move and the handcuffs are on slick as goose $hi+. What neighborhood were they in? Was it nearly impossible not to draw a crowd? You say Chauvin was incompetent, I am not so sure I feel comfortable saying that as I am not a MPD cop. You cannot convict a man for what was in his heart and in his mind, you can only convict him for his actions. You cannot prove anything else.
All of that said, as I have stated I believe three officers will get off and sue the city. Those men will never be able to work as cops again. Chauvin will be charged and convicted of something so they can legally fire him. Floyd was no hero, he was in fact a criminal. Floyd should never have been the focus of protests and riots. Floyd appears to have been loved by his family, but he was a flawed man whose flaws brought him to the meeting with the police and his death.
