Which option defines Security threat groups?

• A. Words that have the effect of manipulating others, due to their strong positive or negative association
• B. Groups within correctional institutions that promote violence against inmates or staff
• C. The study of how space between people is used as part of communication
• D. The process of interpreting body movement and gestures as a form of non-verbal communication

Answer: (B)

Security Threat Groups are organized inmate groups within correctional facilities that promote violence against inmates or staff. This definition matters because it identifies groups that operate with structure and purpose, aiming to control people, resources, and illicit activities inside the institution, which directly threatens safety and security. Recognizing that STGs are formal networks helps staff focus on intelligence gathering, monitoring leadership and recruitment, tracking contraband flows, and implementing disruption strategies to prevent violence and maintain order. The other statements describe different concepts—manipulative use of words, the study of how space is used in communication, and interpreting body movements as nonverbal communication—none of which define organized security threats inside prisons.
