It's said that the best anti-clerical studied by the priest.
I tell the truth I'm a Catholic, but not practicing. If the Pope Francis really wanted to scare the criminal organizations that would be enough to issue an excommunication "against all those who are part of the 5 mafias: the Camorra, Ndrangheta , Mafia, Sacra Corona Unita and Stidda "you'll say How do the priests on the streets,not the ones that stink of sacristy, to know who the criminals are and don't let them to go in the churches ? simple, the mafias seeking popular support,in the cities are know who are the criminals . This gesture suffices to erode the grip of the mafias in the territories.
