Corruption extends upward and downward along the chain of command as long as you have laws on the books which cannot be equitably enforced.
Chances are good that you and I are breaking some law or another right this moment, on Christmas Eve. But we will skate for now because the police can't do 24/7 surveillance of our homes and offices--yet.
Weighed on a risk/reward scale, selling untaxed cigarettes on a street in NYC is somewhere in the middle. Lower than selling dope, I'm sure, but higher than flipping burgers at McDonald's. Get caught selling loosies and the punishment is light, so you set up on another corner once you get out or pay the fine.
It's not that the law or the police are intrinsically anti-black. It's more that New Yorkers most likely to risk being snagged in it are those on the edge of poverty, struggling to feed their family, and blacks make up a disproportionate percentage of that group.
I could, right now, set up a shop on a New York City sidewalk and sell things, without paying rent, due to a post Civil War law. However, that would mean I’d have to live & work in New York City.
The problem is communism is intrinsically anti-black.
