Which of the following defines a security threat group (STG)?

A security threat group (STG) is defined as a group of three or more inmates posing a potential threat. This definition emphasizes the size of the group and the potential risk it presents, which is critical in correctional settings where safety and security are paramount. STGs often engage in activities that can disrupt order and stability, making it essential for law enforcement and correctional personnel to recognize and understand these groups.

The significance of having three or more members is that it typically signifies a more organized structure that can act with collective intent, increasing the likelihood of coordinated actions that pose a threat to safety. This group dynamic is crucial in identifying potential risks within a facility and developing appropriate response strategies.

In contrast, other options either suggest a smaller number of inmates or a focus on non-threatening behaviors. For example, a single inmate with violent behavior does not constitute a group, and a group focused solely on community service is not aligned with the concept of a security threat. Understanding what constitutes an STG allows law enforcement to better manage potential risks associated with inmate populations.
