Dear Health,
So, if Mr. Floyd is still presumed innocent, why do you keep referring to him as a criminal? [And, as resisting arrest for criminal motives.]
Fear of the police, would not stop crimes. It would stop them from being reported. I would not call the Police for an active robbery, if we are more afraid of the Police than the criminals. And it for sure would make no difference, in these high profile cases. They mostly involve incompetent, or vicious cops filing to make an ordinary arrest.
