Which of the following could NOT be a reason for a PSO to cause an arrest?

The justification for the choice that indicates personal bias is not an acceptable reason for a Private Security Officer (PSO) to make an arrest lies in the principles governing lawful arrest and the professional conduct expected of security personnel. A PSO is expected to act with fairness, objectivity, and in accordance with the law. Making an arrest based on personal bias undermines these principles and can lead to violations of civil rights as well as potential legal consequences for the PSO and their employer.

On the other hand, preventing the loss of company property is a legitimate reason for making an arrest, as it directly relates to the protection of the business's assets. Ensuring the safety of customers and staff also justifies an arrest, particularly when immediate action is needed to avert harm. Protecting the rights of individuals involved is critical to the law enforcement process itself, as it ensures that due process is followed, and all parties affected are treated justly. Each of these alternatives reflects the responsibilities of a PSO to maintain order and uphold the law, unlike the arbitrary nature of acting on personal bias.
