officially, there is no such thg as a mafia north of Rome... The M-thg is a pure Sicilian product, yet there is organized crime in the north of the boot as well of course ! It started in the poorest parts where the local ppl needed protection from the invaders and the government which was in the north and considered the south as its vassal.

Never heard abt a Sardinian mafia. The island is really small. One funny thg I recently noticed is that a Sardinian guy owns the biggest internet provider in Europe (Tiscali) and buys the smaller ones one by one thus getting even bigger. It's legal business but it's the first time the island gets the spotlight as far as I know.
