strax is right, except a couple of mafia clans (casalesi, nuvoletta) the camorra is not organized as sicilian mafia or ndrangheta
Speaking of the Casalesi, the difference with the past is that todays groups in Caserta have less established ties to the Schiavone, Bidognetti, Zagaria and Iovine factions (who's leaders are all in prison) and acquired greater autonomy. They also changed their strategy like Provenzano did no more violence and massacres.
