What should a security guard do if they witness a crime in progress?

When a security guard witnesses a crime in progress, the most appropriate action is to call law enforcement and provide as much detail as possible. This option prioritizes the safety of everyone involved, including the security guard, as confronting a suspect can be dangerous and could escalate the situation. By contacting the authorities immediately, the guard facilitates a professional response to the crime.

Providing detailed information to law enforcement is crucial because it helps them assess the situation quickly and effectively, leading to a more efficient response. Details such as the type of crime, physical descriptions of the suspects, the location, and any other relevant observations can significantly aid in apprehending the criminals and ensuring public safety.

The other choices may lead to ineffective responses to the situation. Ignoring the crime avoids confrontation but fails to protect individuals and property, undermining the very purpose of security. Attempting to apprehend the suspect poses significant risks and could lead to injury or legal ramifications for the guard. Notifying a supervisor is important but should occur after alerting law enforcement to ensure immediate action is taken to address the crime.
