"Easy to think that Naples and the Camorra are far away and have nothing to do with us. Yet, any visitor to Europe is likely to pass through Naples, gateway to Pompei, the fabulous Amalfi Coast, and Capri. Take a train from Rome to Naples, then a tram from the Naples train station to the ferry boats. You'll already have rubbed shoulders with Camorra underlings, and may or may not still have your wallet.
I research street crime in Naples (and elsewhere). It took quite a few dangerous years before I realized the risks of snooping around in Camorra business. http://bobarno.com/thiefhunters/2009/02/camorra/"
