In what situation should a security officer call for law enforcement?

A security officer should call for law enforcement when they feel unsafe or witness a crime because their primary responsibility includes ensuring the safety and security of people and property. In situations where an officer observes illegal activity, a potential threat to individuals, or personal danger, immediate law enforcement involvement can be crucial. This ensures that the situation is handled by trained professionals who are equipped to manage criminal behavior and restore order.

Having the judgement to call for help not only enhances the response to the incident but also provides necessary support to the security personnel and affected individuals. This proactive approach helps prevent escalation of the situation and ensures that appropriate legal procedures are followed.

The other options do not emphasize the critical judgment and situational awareness required in security roles. For instance, calling for law enforcement whenever an incident occurs may lead to unnecessary involvement in trivial matters, while waiting for a supervisor's request could delay critical response actions. Additionally, waiting until the end of a shift could leave potential escalations unchecked, which goes against the security officer's duty to maintain safety at all times.
