The Resilience of Criminal Networks: An Agent-Based Simulation Assessing Drug Trafficking Organizations Reactions to Law Enforcement Attempts at Disruption

By Deborah Manzi

Criminal organizations operate in complex changing environments. Being flexible and dynamic allows criminal networks not only to exploit new illicit opportunities but also to react to law enforcement attempts at disruption, enhancing the persistence of these networks over time. Most studies investigating network disruption have examined organizational structures before and after the arrests of some actors but have disregarded groups’ adaptation strategies. The present study investigated the resilience of drug trafficking organizations (DTOs) to law enforcement attempts at disruption, focusing on three main aspects: the ability to endure disruption, react quickly and efficiently to threats, and keep primary functions unaltered. The analysis relied on an agent-based model (ABM) that simulates drug trafficking and dealing activities by organized criminal groups and their reactions to law enforcement attempts at disruption. The simulation relied on information retrieved from a detailed court order against a large-scale Italian DTO and from the literature. The results demonstrated that law enforcement interventions are often critical events for DTOs, with high rates of disruption. However, surviving DTOs always displayed a high level of resilience, with effective strategies in place to react to threatening events and to continue drug trafficking and dealing.
