“mr floyd’s past has nothing to do with his murder or manslaughter.”
Completely wrong. His past has everything to do with what happened to him because it shows what kind of person he was, that he had habitually been in conflict with the law and law enforcement and that he was prone to violence. All those are elements of how he had to be handled. If he had not resisted arrest this would not have happened, it’s as simple as that and only the willfully blind refuse to see it.
in this sense you are wrong... as soon as mr floyd was compliant, the officer had no right to kill him. being cuffed and on his belly was all the past that mattered and the officer, and you, refuse to see that.
