Gang violence is a problem across major U.S. cities, with over 21,500 gangs and 731,000 members. Gangs are responsible for about half of all homicides in major cities. The document lists several local Rhode Island gangs such as the Hanover Boyz in Providence and the Asian Outlaw Boyz in Cranston. Gangs form partly due to a lack of support systems, and offer companionship and money from illegal activities to entice new members. Gangs negatively impact communities as their criminal activities are tolerated more than law enforcement.
