Mobs are large groups of people who come together, often in a spontaneous manner, to express a common interest or emotion. They can form for various reasons, such as protests, celebrations, or social gatherings. While many mobs are peaceful, some can become chaotic or violent, leading to disturbances in public order. In the context of crime, the term "mob" often refers to organized crime groups, such as the Mafia. These groups engage in illegal activities, including extortion, drug trafficking, and racketeering. They typically operate in secrecy and have a hierarchical structure, with leaders who control various operations.
