What is the best action if a security guard encounters a suspicious person?

The best action when a security guard encounters a suspicious person is to observe and report the behavior. This approach is effective because it allows the security guard to gather important details about the individual and their actions without escalating the situation unnecessarily. By observing, the guard can assess the level of threat or risk the person may pose, which is critical for making informed decisions later.

Reporting the suspicious behavior to a supervisor or law enforcement ensures that appropriate measures can be taken based on the context and the assessment of the situation. This method prioritizes safety for both the guard and others in the vicinity, maintaining a professional demeanor rather than creating a potentially confrontational encounter.

Directly confronting the suspicious person might lead to an escalation and could put the guard or others in danger, while ignoring the behavior could result in failing to address a legitimate security risk. Calling the police immediately could be warranted in more serious situations, but in many cases, observing the behavior first provides a better foundation for further action.
