Organized crime groups are structured criminal organizations that engage in illegal activities for profit. These groups often operate in secrecy and can be involved in various crimes, such as drug trafficking, human trafficking, and extortion. They typically have a hierarchical structure, with leaders and members who perform specific roles to maintain the group's operations. These groups can vary in size and scope, ranging from local gangs to international syndicates. They often use violence and corruption to protect their interests and evade law enforcement. Notable examples include the Mafia, Yakuza, and Cartels, each with unique characteristics and methods of operation.
