I have never encouraged or accepted the idea that police should be killing unarmed people.  Yes, some cops, over the years have worked with the Klan.   That is not the case with ALL police.   I think you are doing a disservice to many police forces.   Does it help encourage the police forces to protect and serve black Americans to greet them with hate?   That is what I am suggesting when I say the viscous circle must be broken.   You are not going to encouraging the cops to be on your side if you greet them with a raised fist.  I also say the same thing to the cops.
