If he is saying that how is it racist. He is saying that the greatest risk to citizens from cops is when White cops patrol high population Black areas that's where cop watching can prevent bad behavior to Black people. Hardly sounds racist to me.
I must be a racists. I think Black areas exist and it's a neutral observation based on numbers.
Black areas patrolled by racist white cops would be where the trouble is.
Because of the number and newsworthiness of White police abuse of Black people the opinion, if that is his, can just be if White cops were kept out of Black areas there would be less abuse going both ways and life would be better for everybody. I am not saying that is my opinion, only that it is an opinion one might hold without being a racist.
Already went over this. The point of cop watch is to prevent police abuse. Many cops are White and racism is color blind as to whom may be infected by it.
He specifically says White and Black cops above. Neither White or Black cops, he may feel, should resort to physical violence when they interact with the public. I believe in self defense so that would be the ideal but not practical in all cases.
