They overcharged them for sure. The original 3rd degree charge seemed appropriate and would require prosecutors to show that he caused Floyd's death while perpetrating a dangerous act without regard to human life.
Then after the mass protests it was bumped up to 2nd degree, so now it has to be shown that Chauvin actually intended to kill Floyd and not intend to restrain him. Chauvin is going to walk.
What's the point of even having different races then? They've already removed all racial class restrictions, so with this there's no difference whatsoever.
