What is the role of an investigator?

• A. To ensure the justice system has the information required to make the appropriate decisions.
• B. To arrest without evidence.
• C. To supervise field officers.
• D. To prosecute in court.

Answer: (B)

The central function of an investigator is to uncover facts and gather evidence that explains what happened. This involves collecting information from witnesses, examining crime scenes, reviewing documents, and coordinating with forensics and other specialists to build a solid factual record. The goal is to support informed decisions by prosecutors and to enable a fair, evidence-based case in court. Arrests rely on probable cause grounded in reliable evidence, so doing so “without evidence” would violate due process and isn’t the investigator’s role. Supervising field officers and prosecuting in court are distinct responsibilities held by different positions, not the investigator’s primary duty. So the emphasis is on discovery, verification, and documentation of what occurred.
