Underworlds refer to the hidden networks and activities associated with organized crime. These criminal organizations often operate outside the law, engaging in illegal activities such as drug trafficking, extortion, and human trafficking. Members of these groups typically maintain a code of silence, known as omertà, to protect their operations and avoid law enforcement scrutiny. The underworld is characterized by its hierarchical structure, where leaders, often referred to as bosses, oversee various operations. These groups may also have connections to legitimate businesses, allowing them to launder money and expand their influence. Law enforcement agencies work tirelessly to dismantle these networks and bring criminals to justice.
