Police officers have significant discretion in how they enforce the law. This discretion allows officers to consider the totality of circumstances in each situation rather than following rigid guidelines. It enables officers to make judgments about issues like whether to arrest someone or issue a warning. While discretion provides benefits like catering decisions to individuals and preventing overburdening of the courts, it also presents disadvantages if not used appropriately. Overall, properly exercised discretion is a necessity for effective policing.
