Criminal networks are interconnected groups or organizations involved in illegal activities such as drug trafficking, human trafficking, cybercrime, and organized crime. These networks operate through a hierarchical structure with clear roles and responsibilities, and often rely on violence, intimidation, and corruption to maintain control and power. Researchers in this area study the structure, behavior, and dynamics of criminal networks, as well as strategies for disrupting and dismantling them. This research can inform law enforcement and policy makers in efforts to combat organized crime and protect communities from the harmful effects of criminal activities.
