Which of the following can be displayed on a security guard badge or uniform?

The correct answer is "Security Officer" because this title accurately describes the role and function of an unarmed security guard. Using "Security Officer" on a uniform or badge clearly indicates the individual’s position and helps to distinguish them from law enforcement personnel. This differentiation is important as it conveys the scope of authority and responsibilities that are specific to security personnel, who typically do not have the same powers as police officers.

In contrast, designations like "Police," "Deputy," or "Patrolman" imply a law enforcement capacity and could mislead the public regarding the authority and powers of the individual wearing the uniform. Misrepresenting oneself as a law enforcement officer can lead to legal repercussions and confusion regarding the roles and responsibilities of security personnel. Therefore, it is crucial that security guards represent themselves accurately and within the bounds of the law by using appropriate titles like "Security Officer."
