Nicky, many Sicilians, not just mobsters in Sicily, but civilian ones believe in omerta still, where they don't tell the cops anything. The fresher Sicilian they are, the less they'll talk to the feds, and most of the Rizzuto's are true Sicilians. The head members of the Bonanno's used to be back when old Joe was running things, but now they are as American as it gets.
