What are the three types of investigations conducted?

The correct answer highlights the three types of investigations typically conducted within a police department context. Internal Affairs is crucial for addressing allegations of misconduct with police personnel, promoting accountability and integrity within the force. The Division refers to investigations that are carried out at different levels of the police structure, often examining the operations or actions of various divisions within the department. Division Referral encompasses cases that might involve instances where issues identified in one division are forwarded to another for further examination or action, ensuring thorough scrutiny across different segments of the department.

Understanding these categories is essential because they ensure that various aspects of police work are overseen and reviewed comprehensively, maintaining a high standard of professionalism. The other options incorporate terms like External Affairs and Civilian Review Board, which, while related to oversight and accountability, do not specifically represent the standard categories of internal investigations within a typical police framework. This distinction is important for recognizing the internal mechanisms that police departments use to evaluate and improve their practices.
