100% agree....Naples and to a lesser extent Cosa Nostra is highly concentrated in their geographical area although the Sicilians have always had a hard time managing urban mafia clans vs more rural clans.

The Sicilians and camorra are also very present in central and n9rthern italy and it seemseems from Italian police investigations that the three syndicates divide territory accordingly therefore rarely if ever going to war. To be honest the Canadian situation seems to be more unique where the rivalry seems more plausible.
