What should a security officer do if they haven't witnessed a crime directly but have heard screams?

The recommended action for a security officer hearing screams without directly witnessing a crime is to investigate and gauge the situation cautiously. This approach allows the officer to assess the context and nature of the situation, which is crucial in determining whether there is an actual threat or if it could be a non-threatening scenario.

By investigating, the officer can gather more information, evaluate the environment, and ensure their own safety while also being prepared to respond appropriately. This measured response helps to prevent unnecessary panic and escalation, ensuring that assistance can be provided where needed without jumping to conclusions or making assumptions about the situation.

In contrast, simply assuming it is a false alarm neglects the potential seriousness of the situation. Calling for police backup without any initial assessment could lead to a misallocation of resources if the situation is minor or non-threatening. Fully engaging with involved parties without understanding the context can also put the officer at risk and may not lead to a productive resolution. Therefore, a cautious investigation is the most sensible and responsible course of action in such cases.
