From the introduction of the editors:

Ingo Fiedler describes in detail how money laundering (which is a necessity for the organized crime) works and how this can be done through online gambling. He identifies eight factors why online gambling systems can be used for money laundering. Furthermore, the transaction structures of different types of money laundering are described on the basis of a drug dealer and the different scales of his criminal proceeds. Fiedler discusses the relation between the costs of money laundering and the crime level in society. In his opinion, it is necessary to enforce the laws against illegal operators in offshore jurisdictions.
