Don't know much about the Mafia in Italy. I believe there are three different groups. One in Sicily made up of about 100 different clans, one in Calabria and one in Naples also made up of many many clans. Don't really understand how they cooperate together. There main business is the manufacturing and distribution of heroin. I believe a few Clans work together in a particular area and have a person represent them to the other clans in different areas. Each Clan seems well organized and secretive like the Chicago Outfit. I also know one other thing, those stupid blue collar made guys in the Bonnano Family were afraid of the Zips who were sent here to be on the receiving end of the heroin shipments years ago. They stayed out of their way.
