Biker gangs have become increasingly sophisticated in recent years. New gangs are forming and old gangs are building with little recognition from law enforcement. Biker clubs lack the organizational polish of organized crime, but they maintain hierarchical structures with bylaws, constitutions, dues, and rules. Bikers make a point of learning about law enforcement so that they can learn from police mistakes. Bikers use computers, cellular telephones, complex surveillance equipment, sophisticated weaponry, and pagers. Motorcycle gangs network with other types of gangs and countercultures, such as prison gangs and white supremacists. They have sometimes formed liaisons with police officers or other government officials. Their mottoes illustrate their beliefs and values. To address motorcycle gangs effectively, police must use cooperation, communication, and commitment. Photograph
