My step-grandfather use to tell me how much of Baltimore's police force got down. The evil they would do, like beating brothers in paddy wagons and stashing false evidence on people. They would spill everything to him, thinking he was some Greek guy. The only advice he was able to give me was to avoid them at all costs.
I learned that lesson up-close when one arrested me for a noise violation as a teenager (boom box playing outside of a bowling alley). While he was handcuffing me, he was telling me how if I tried to run he would shoot me in the back or how he would drop me off in some area in Baltimore where the racists lived. The only thing that really saved me was that I was only 15, but this brother who was 18 that just came over the hill at the time was arrested for the same charge. He was not even with us, and I told the cop that, but a paddy wagon was called to take him anyway. Here is the kicker of it all, the arresting officer was a Black man. That self-hatred can be very strong with some of those lost brothers.
