ABSTRACT
This chapter provides an overview of some organized crime groups to give the reader a basic understanding of them and to identify some clear differences. Culture and years of individual sociological traits and criminal activity have clearly identified certain sectors as organized groups. The migration of Russian organized crime cells to many parts of the world has been cause for great concern. In general, the Asian organized crime groups have been very attracted to financial crimes. One of the most significant crimes attributed almost entirely to Nigerians is Advance Fee Fraud (4-1-9 Fraud), which is named after the Nigerian law that identifies such fraud crimes. The Mafia is very much associated with illegal market enterprises. These are typically enterprises that arrange contract types of agreements among the participants. The Mafia monopolies in local communities discourage new business and control and even drive out old investors and similar business enterprises.
