Law Enforcement Guide to Texas Street Gangs

This booklet is published by the Texas Department of Public Safety, Criminal Intelligence Service, with the cooperation of the Texas Department of Criminal Justice-Security Threat Group Management Office.  It is being provided as a resource to assist law enforcement agencies and correctional staff in identifying possible members of Security Threat Groups (STGs) and is not to be disseminated outside your agency.  This booklet contains historical synopses of all STGs recognized by the Texas Department of Criminal Justice (TDCJ), as well as recognized tattoos and other related indicators most often used by STGs and various street gang members. Gang members may change or modify the tattoos as corrections officials and law enforcement identify them as gang-related. The dynamics of these groups are also subject to change.
