Your first sentence just repeats what I said almost exactly. Except that prior drug use would be relevant because it would bolster a belief that he was on drugs now based on observations of the police and of the security guard.
Whether George Floyd was a man of even decent character has everything to do with the public narrative that police are out there killing good people for no reason at all and the implication every interaction that results in use of force is unwarranted. The fact that the narrative is absolutely wrong on Trayvon, on Hands Up Don’t Shoot, on others is relevant in the court of public opinion.
Almost every one of these national cases has tried to claim that the person killed was a good person. Why is that if it’s not relevant? You know the answer, will you be honest about it?
Why hasn’t the media covered that Floyd has a history of violent crime and drug use? That should be relevant to the story, so why not cover it?
