What should a security guard do upon witnessing a crime?

When a security guard witnesses a crime, the appropriate course of action is to report it to law enforcement immediately. This response is crucial as law enforcement officers are trained to handle criminal situations and have the authority to take action to prevent further criminal activity, pursue suspects, and gather evidence. Prompt reporting ensures that trained professionals can respond quickly to the incident, which can be critical for preserving evidence and protecting the safety of individuals involved.

Other actions, although they may seem reasonable, could impede proper protocol or put the guard at risk. For instance, intervening physically can be dangerous and may escalate the situation, making it more hazardous for the guard and others. Taking photographs of the scene can be helpful in some circumstances but should come after notifying law enforcement to ensure the scene is secured and evidence is properly managed. Waiting for backup might delay a response to the crime, potentially allowing the situation to worsen or allowing the suspect to escape. Thus, the immediate priority should be to alert law enforcement.
