Cool part from an article,found it on "Joe Bruno On The Mob" site about a connection between C.Gambino and big time drug dealer Louis Civillo(wich i cant find any info bout this guy) and the "suspicious" law against dope placed by the N.Y. Mob Bosses at the time...

While recuperating at home, Gambino broke one of the laws he decreed himself — “Deal Drugs and Die.” Acting Genovese boss Thomas “Tommy Ryan” Eboli approached Gambino with a “can’t miss” proposition to broker a multi-million dollar drug deal with Louis Civillo, considered by the Feds to be the biggest narcotics dealer in America. The problem was, Eboli, a former boxing manager and notoriously bad gambler, did not have the $4 million needed to proceed with the operation. Gambino fronted Eboli the $4 million, but he lost it all when the Feds arrested Civillo, and confiscated the drugs and money. When Gambino approached Eboli about his missing $4 million, Eboli turned his pockets inside out, indicating he was flat broke.

This did not please Gambino too much. As a result, at approximately 1 a.m., on July 16, 1972, Eboli was shot five times while he was leaving his girlfriend’s apartment in Crown Heights, Brooklyn. Eboli died on the spot, and Gambino had enough influence in the Mafia Commission to order that his close pal, Genovese captain Frank “Funzi” Tieri, would now be the new boss of the Genovese Family. And so it was done.
