Which of the following would not be considered a sign of gang activity?

High inmate morale is not typically associated with gang activity. In the context of a correctional facility, gang activity is often linked to behaviors and signs that indicate affiliation or influence, such as involvement in violent acts, frequent requests for housing changes that may relate to gang protection or influence, and the displaying of gang tattoos, which serve as a clear marker of gang affiliation.

Conversely, high inmate morale suggests a positive environment among inmates, which is generally not an indicator of gang presence or influence. In fact, strong gang activity typically leads to tension, fear, and division among the inmate population, which would not support high morale. Thus, high morale stands apart from the other options that directly relate to the manifestations of gang dynamics within a correctional setting.
