Street gangs and mobsters hardly interact on the streets. On a street level both groups don't tend to stray far from their respective strongholds. There probably are connections between some soldiers and gang members here and there. The mafia arent the drug suppliers they once were and no longer have any real power in any of the state prisons in their own city where the street gangs seem to thrive so theres no real reason for them to work together or even come across each other. The luchesse bloods thing was basically one made guy trying to make a buck, but it was an interesting case because they needed the bloods help in trying to stop another blood from extorting an associate. Someone posted the wire tap transcripts on here once but i cant find them.
