When I read "people of color" anywhere, I assume myself excluded.
Maybe you should keep reading, then.
Also the statistical makeup each community is going to vary; so in some places you might be correct about "half to a local majority" of the community being white (not sure if that's what you meant), in other places, it'll be the other way around.
"The increasing use of surveillance technologies by local police across America, especially against communities of color and other unjustly targeted groups, has been creating oppressive and stigmatizing environments in which every community member is treated like a prospective criminal. Many communities of color and of low income have been turned into virtual prisons where residents’ public behavior is monitored and scrutinized 24 hours a day."
The biggest failing with the democratic party is thinking that centrists or conservatives are not worth addressing, and it continues to earn them defeat.
