Which of the following is NOT a key responsibility of a security guard?

The correct answer identifies that conducting interrogations is not a key responsibility of a security guard. Security guards are primarily tasked with maintaining safety and security within their designated areas. Their main responsibilities typically include patrolling premises to deter and detect signs of intrusion or disturbances, monitoring surveillance equipment to observe and respond to incidents in real-time, and reporting incidents to the relevant authorities or supervisors.

Conducting interrogations, on the other hand, falls outside the standard duties of a security guard. This task generally requires law enforcement training and authority that security guards do not possess. Security officers are expected to observe situations and report their findings rather than engage in investigative or interrogation practices, which are reserved for police officers or other law enforcement personnel. This distinction clarifies the boundaries of a security guard's role in the safety and security framework.
