Mafia families throughout Italy vigorously enforce their local territories but apparently the Rome capital is open territory for all crime groups where much of their dirty money is laundered as reported by Michael Day for The Independent: "a total of 45 gangs -- from the 'Ndrangheta of Calabria, the Camorra from Naples, various Rome crime families and even Nigerian gangsters -- are collaborating in the corruption-mired city, according to a report compiled by Rome's police headquarters":
"Rome is the real money-laundering centre for the money earned from drug trafficking, arms, extortion, illegal money lending and prostitution," says the report. It notes that "organised crime in Rome does not have the same characteristics as in other Italian regions such as Sicily, Calabria and Campania, where you see an almost military presence of the various mafia groups. In the capital, you see different mafia organisations in cahoots with local crime groups."
Sounds a bit like Rome is a sanctuary city for organized crime as long as it's money and not blood that's flowing.
