For what reasons might an officer be subject to suspension or discharge?

The reasons for an officer being subject to suspension or discharge often revolve around serious matters that impact their ability to perform their duties effectively and uphold the law. Neglect of duty is a significant concern, as it implies that an officer is failing to fulfill their responsibilities, which can undermine public trust and safety. Additionally, improper use of substances can severely impair an officer's judgment and performance, posing risks not only to themselves but also to the community they serve. Therefore, this option highlights critical behaviors and actions that law enforcement agencies must address to maintain standards of professionalism and accountability, thereby justifying the consequences of suspension or discharge for officers who engage in such conduct.

While other options mention various performance issues and personal matters, the legal and ethical implications of neglecting duty and substance abuse are particularly compelling reasons for disciplinary actions in the context of law enforcement.
