Which of the following could be a sign of distress in an offender's appearance?

A sweaty forehead can indicate physiological signs of distress, such as anxiety or fear. In a correctional facility, where many offenders may experience heightened emotions or stressful situations, increased perspiration is a common reaction. This physiological response can be a significant indicator of an offender's mental state and emotional distress, reflecting their internal struggles.

The other choices describe indicators that suggest a stable or positive emotional state rather than distress. Well-combed hair, bright eye contact, and a smiling face typically suggest confidence, calmness, or contentment, all of which are not representative of distress. Recognizing the signs of distress, like a sweaty forehead, is crucial for correctional officers as it can guide them in providing the necessary support and intervention for offenders experiencing mental health issues.
