One of the problems I see is that you want to put names and photos to organizations. However, whether it's the mafia, the Hells Angels or street gangs, they're all doing the same thing. Criminals have different friends, different associates and different associations, but, in fact, they are doing exactly the same thing. The Hells Angels and the mafia have agreed to share territories at certain times. The street gangs do the dirty work for the mafia. Murders take place in Montreal. A black man who was a member of a street gang was hired to carry out a contract. The person targeted was a big mafia member. These groups have frequent connections.
Putting them in boxes, names... When the Italian police says that the mafia has been dismantled, it's speaking the truth. They have dismantled an organization called the mafia, but the individuals who haven't been arrested have re-established another organization. They carry different names, in various regions of Sicily, but the result is exactly the same.
