Which factor is NOT an example of a personal value that influences officer discretion?

Professional training is considered a factor that influences an officer's actions and decision-making but is distinct from personal values. Training provides law enforcement officers with the necessary skills and knowledge to perform their duties objectively and according to legal standards. It encompasses policies, procedures, and legal frameworks that guide an officer's conduct in various situations.

In contrast, personal beliefs about justice, cultural background, and the influence of peers are considered personal values because they stem from the individual's background, upbringing, and social interactions. These personal values can shape how an officer views situations, prioritizes certain actions, and exercises discretion in the field. Therefore, while professional training is critical for ensuring compliance with laws and regulations, it does not fall under the category of personal values that affect officer discretion.
