What do you mean by "the way they're deployed disproportionately?" What is "disproportionate" in this context? Disproportionate by race in terms of the officer-to-citizen? Disproportionate to the crime rate? Do you mean that they have more patrols through areas with less crime than those with more crime...because if they have more patrols through areas with more crime, that would not be disproportionate.
Back in the 80s, one real case of police systemic racism was discovered in Omaha NE (a city with a significant racist history). The police department typically assigned its rookies and "problem" officers to the black North Side, while the favored officers were assigned to the wealthy white West Side. But that was 40 years ago.
In nearly 70 years of being black, I've had five "business" interactions with police. My first, at age 15 1/2, was driving without a license and getting in a fenderbender. The white Oklahoma police officer looked closely at me, decided I wasn't a real troublemaker, took me back home, and left me in the custody of my mother...no further action. The only officers I ever felt disrespected me were two black Washington DC officers, who cuffed and stuffed me on a humbug...and I had been the person who called 911 for their help.
One thing I believe has helped me is something my Army father instructed me about getting along in the military: "If you ever find yourself in trouble...Shut up! Running your mouth is only going to make them determined to find some reason to hammer you. Just shut the <bleep> up."
Dialing 911 is like opening a box of chocolates.
