The SOCTA 2021 provides an overview of the current state of knowledge on criminal networks and their operations based on data provided to Europol by Member States and partners and data collected specifically for the SOCTA 2021. In trying to overcome the established, and limiting, conceptualisation of organised crime groups, this assessment focuses on the roles of criminals within criminal processes and outlines how a better understanding of those roles allows for a more targeted operational approach in the fight against serious and organised crime.
