This has been told by the people who relocated, because they were not willing to risk their children. Another example: if you start your business there, someone from "the family" will come after a while and tell you: "You need a secretary. And I have found one for you." Now if you reject them, they will go after you. This is why people are leaving. It would be a beautiful place to live, but because of this, people are living. Many Italian politicians tried to fight "the family", most of them were killed.
No offense, but from what I know that is exactly what an anecdote is. As for your claim about the mafia, I have no idea personally but good thing you mentioned it.
