The U.S. Department of Justice defines Outlaw Motorcycle Gangs as organizations whose members use their motorcycle clubs as conduits for criminal enterprises. OMGs are highly structured criminal organizations whose members engage in criminal activities such as violent crime, weapons trafficking, and drug trafficking. ATF defines One Percenters as any group of motorcyclists who have voluntarily made a commitment to band together to abide by their organization’s rules enforced by violence and who engage in activities that bring them and their club into repeated and serious conflict with society and the law.

Street Gangs are located throughout the United States, and their memberships vary in number, racial and ethnic composition, and structure. Large national street gangs pose the greatest threat because they smuggle, produce, transport, and distribute large quantities of illicit drugs throughout the country and are extremely violent.
