By utilizing communication data, electronic surveillance materials, and other investigative sources, the work provides valuable insights into the partnerships and hierarchies within these organizations. The case studies and analytical approaches allow for the identification of central research challenges and an understanding of the balance between efficiency and security in criminal structures. This book is aimed at professionals in the fields of criminology and organized crime, as well as social scientists interested in the dynamics of illegal activities.
