lcn have a certain niche when it comes to gambling, unions and labour racketeering. I think with the russians during the seventies and eighties they were able to muscle in on the gasoline bootlegging scam by getting the families to work together they were able to make sure that the russians couldnt win against them. The russians in turn knew they were outnumbered and also probably didnt want them to expose themselves to the authorities through any conflict. also i think they benefitted from the relationship as a fairly new group. That changed though as time went on and more and more russian gnagsters started to move to the us especially after the soviet union fell. The first wave of russian gangsters were alot more cooperative and more i suppose godfather-like than the ones that came after. I think thats the only major modern example of the lcn muscling in on another ethnic crime group.
