Organized crime refers to structured groups that engage in illegal activities for profit. These groups often operate in a systematic manner, using violence, corruption, and intimidation to maintain control over their operations. Common activities include drug trafficking, human trafficking, extortion, and money laundering. These criminal organizations can vary in size and scope, from local gangs to international syndicates like the Mafia or Yakuza. They often exploit legal businesses to launder money and expand their influence, posing significant challenges to law enforcement and public safety.
