Probation officers are responsible for enforcing supervision conditions, reducing the risk offenders pose to the community, and providing correctional treatment. Probation officers may need to be trained in specialized risk management techniques to identify, track, and supervise offenders affiliated with community threat groups. Community threat groups are defined as groups of individuals who engage in antisocial and illegal behavior and who pose a danger to criminal justice personnel and/or the general public. Such groups include street and youth gangs, prison gangs, drug and organized crime organizations, and cults and aberrant social movements. The history of gangs in San Antonio, Texas, is reviewed, and an organizational framework for developing a specialized community threat group identification and supervision program is described. Duties and responsibilities of community threat group coordinators are identified. 16 references
