There is a very interesting movie out at cinemas now. I hope they will translate in english.
It explane very well the situation in south italy.
The movie name is "Gomorra".
Gomorra is a nickname of Camorra, a kind of mafia. Mafia is the knewest name in the world, but the main place of it is in Sicily. Camorra is in another region, near Naples. N'drangheta is in Calabria region.
What they do is similar, but the territory is different.
