I don't even think I'll see the American mob disappear in lifetime, let alone the Sicilian mafia. Internationally there's just less reports on the Sicilians because the newspapers developed a new hard-on for the Calabrians the last few years.
in italy sicilian mafia controls some media/newspapers, so it's sure a strategy to hide it, in the states i don't think they still have this kind of power, the times of hoover who denied the mob existence ended
