That happens when everybody knows everything.
In Napoli, Palermo, Cagliari, nobody sees,nobody hears, nobody knows, because evrybody knows who resp. Camorra, Mafia and N´drangheta are and everybody has something to earn and a lot to lose.
That is the way you can build the biggest network of criminals that lives on the shoulders of the many who work and believe in "democracy, law and order".
If there were less believers and more viewers, may be, we would have hopes.
