First off, the thread is about the mafia working with other OC groups.
So we are not talking about low level street thugs.
Like we said, some street gangs or groups have become big and are organized crime.
Yes you have crips or bloods that are not at the level of the mob. And the mob will never work with them.
But you have gangs in the UBN, the Latin Kings etc .

that are OC and work with the mob. The mob always work with other crime groups in his history.

The rest is just you fantasizing about the mob.
