A gang of 3 worked the Circumvesuviana today. They were on the train when it pulled up at Pompeii Scavi heading back to Naples and as the large crowd boarded the train they pushed to get off it. A well-dressed guy stood just inside the train door, I suspect taking booty from the two junkie thugs as they pushed their way through picking pockets. I saw them coming and shoved my hands in my pockets just as thug #1 went for it. He only took his hand out and backed off when I screamed in his face, at which point they knew they were busted and jumped off the train.
These guys were easy to pick amongst the tourists and easy-going locals. Dead-eyed junkies in cheap track suits and bad caps look the same all over the world!
