What is the recommended action if a security guard witnesses suspicious activity?

When a security guard witnesses suspicious activity, notifying the appropriate authorities or supervisors is the recommended action as it ensures that trained professionals can assess and address the situation properly. This approach helps maintain safety by involving individuals who have the authority and resources to manage potentially dangerous situations.

Additionally, bypassing direct confrontation minimizes risks to the security guard, as approaching a suspicious individual could lead to escalation, potentially resulting in harm or conflict. Ignoring the behavior completely, on the other hand, could allow a situation to develop into something more serious, potentially endangering others present. Waiting to see if it escalates is also not prudent; taking proactive measures is essential in ensuring safety and security.
