What is the appropriate action for a security officer when encountering a trespasser?

The appropriate action for a security officer when encountering a trespasser is to ask them to leave. This response adheres to the fundamental responsibilities of a security officer, which include maintaining safety and order on the premises. By requesting the trespasser to leave, the officer takes a proactive stance in addressing the situation without escalating it unnecessarily. This action demonstrates an understanding of conflict resolution and helps to ensure the safety of both the trespasser and others present.

Engaging in dialogue by inviting the trespasser for an interview can lead to confusion and does not address the primary issue—the need to remove the individual from the property. Ignoring their presence could lead to further complications or potential safety issues, as the trespasser may engage in unwanted behavior. Physically removing the trespasser is not typically advised unless absolutely necessary, as it could escalate the situation and pose safety risks to the officer and bystanders. Therefore, asking the trespasser to leave is the most appropriate and responsible action for a security officer.
