Organised crime refers to structured groups that engage in illegal activities for profit. These groups often operate across various regions and can involve a range of criminal enterprises, such as drug trafficking, human trafficking, and extortion. They typically have a hierarchical structure, with leaders and members who carry out specific roles. These criminal organisations can be local, national, or international in scope. Notable examples include the Mafia, Yakuza, and Cartels. Law enforcement agencies worldwide work to combat organised crime, as it poses significant threats to public safety and can undermine legal economies.
