As a researcher on Black OC from the 1920-70 in various cities, police corruption was everywhere. The Black racketeers did have police, judges, and alderman/councilmen on their payroll or bribe. Profits speaks louder than racism generally. From paying the county sheriff in Mississippi to supporting the alderman in Bronzeville, Chicago. Major rackets of that time was Gambling ( Numbers, Policy, Cards & Dice), Bootlegging ( some people don't know that) , Prostitution & Drugs trade ( most spoken obviously). There was a national policy association that included kingpins/queenpins from NYC, Chicago, Philadelphia, Baltimore, Cleveland, Detroit, Milwaukee, Gary, St.Louis, Indianapolis, DC, Nashville, & Atlanta. I could be missing a few other cities. During the 30-40s was the peak of the numbers/policy racket moneywise in Midwest/Northeast black communities along in the West too. The South is a mix bag of gambling & bootlegging rackets in the black communities.

I think due to L.E ( law enforcement) , Criminologists, & Mainstream media use La Cosa Nostra as the model to set the definition of OC when it's ambiguous definition wise. Add the USA history of discrimination than it's viewed as non-white crime groups can't form similar syndicates which is completely untrue. Each group is different just like the Jewish mobs to Irish mobs. Black syndicates are structured to facilitate the racket like a business not a club/fraternity setting. That's the common misunderstanding when comparisons are made to LCN. The growth of street organizations and 1% club shaped the black underworld.

The sports & music industry have a long history with the black underworld prior to hip-hop formation. Jazz to Rock N Roll to Disco along with Boxing & Baseball have indirect ties to Black racketeers. Everybody heard of Joe Louis and his manager was John Roxborough, well Roxborough also was one of Detroit's premier numbers kingpin.
