A mob, often referred to as a gang, is a group of individuals who come together for a common purpose, typically involving illegal activities. These groups can vary in size and structure, and they often engage in organized crime, such as drug trafficking, extortion, and racketeering. Members of a mob usually have a strong sense of loyalty to one another and may use violence to protect their interests or territory. Mobs can be found in various cultures and regions, with some of the most notorious being the Italian Mafia, Yakuza in Japan, and MS-13 in Central America. Law enforcement agencies often work to dismantle these organizations due to their impact on communities and public safety.
