What should a security guard do if they witness a theft?

When a security guard witnesses a theft, the appropriate course of action is to call the police and provide detailed information about the incident. This response is crucial because law enforcement is trained to handle criminal activities effectively and safely. It ensures the situation is dealt with by professionals who have the authority and resources to confront and apprehend suspects.

By contacting the police, the guard also preserves evidence and allows for proper documentation of the crime, which can be vital for any subsequent investigations or legal actions. It is important for the security guard to maintain a safe distance from the situation, as confronting a thief directly can escalate the incident and put the guard and others at risk. Moreover, attempting to recover the stolen item personally could lead to complications, including physical confrontations or legal repercussions, as private citizens have limited powers in detaining suspects. Therefore, calling the police is the most responsible and legally sound action to take in response to witnessing a theft.
