I just bought a book called "The Turkish Mafia", like the title says its about the Turkish mafia. It describes the origins and what the status is today, its fascinating to see how similair the origins are between the Italian/Sicilian mafia and the Turkish mafia. Both groups emerged in the countryside, the prisons. And both are described as men of honor, as Robin Hood characters. But in reality honor wasnt that important, and the most important imo is the close ties the Turkish mafia has with the government, also similair to the relation with the mafia in Italy. Not to mention the close co-operation between the Sicilian Cosa Nostra and Turkish drug baba's (godfathers) during the Pizza Connection. Today, the Turkish mafia works closely with the italian organizations, and control up to 80% of the heroin business in western europe. its a good read
