What is one purpose of a security guard's duty to intervene?

The primary purpose of a security guard's duty to intervene is to prevent harm to others and protect property. This duty emphasizes the security guard's role as a protector, which is central to their responsibilities. When a security guard intervenes in a potentially harmful situation, they are actively working to stop crimes from occurring or escalating, thereby ensuring the safety and well-being of individuals and the security of property under their watch.

By prioritizing the prevention of harm and property protection, security personnel not only fulfill their legal obligations but also demonstrate their commitment to maintaining a safe environment. This proactive approach can deter criminal activity, reassure the public, and contribute to a sense of security within the premises they are tasked to monitor.

The other options do not align as closely with the primary responsibilities and moral imperatives associated with security guard duties. For example, while assisting in criminal investigations may be a function of law enforcement rather than a security guard's primary role, issuing tickets and creating disturbances would be counterproductive to the security guard's mission to maintain order and safety.
