Yes african american have a large network. I thinks the african american organized crime groups are linked to many other organized crime groups around the world. Black american do import drugs to the US with the help of their connections, from many hispanics or black countries. Lets not forget, the US is the biggest market for drugs. Groups like BMF, JBM, GDs and others are well know. But their are other groups that are in the shadows, until the FBI or the news start talking about them.

They are also in gambling, money laundering, scams and i’m sure white collar crime.

I think the biggest problem about black organized crime in the US, is gangbanging. Gangbanging doesn’t help a group to grow, because gangbanging make hustlings more difficult, because of the attention of laws enforcement and other gangs.
