I think that the Federal Bureau of Narcotics was very well aware about the Outfit's involvment in drugs. In the early 1960's the feds cracked down a 10 million dollar a year narcotics ring that controlled over 80% of the trafficking in Chicago. The boss of that crew was Giancana's guy Pete DePietto. DiPietto's crew was consisted by members like Joe Battiato,Teddy DeRose, Angelo Passinni, Solly Monte, Frankie Carriscia and Mike Demaro. The crew had connections to drug traffickers from St.Louis, Detriot, KC, LA and Cleveland. The crew also imported heroin from France through Canada and also from South America. DiPietto had close connections to Rocky Infelice, who was also once arrested for narcotics trafficking, and Charles Nicoletti.
