Criminal organizations are groups that engage in illegal activities for profit or power. These groups often operate in secret and can range from small gangs to large, sophisticated networks. They may be involved in various crimes, such as drug trafficking, human trafficking, or extortion, and often use violence or intimidation to maintain control and avoid law enforcement. Many criminal organizations have a hierarchical structure, with leaders who make decisions and members who carry out tasks. Some well-known examples include the Mafia, Yakuza, and Cartels. These organizations can have a significant impact on society, contributing to crime rates and undermining legal systems.
