Investigation vs. Interrogation

Key Differences

Investigations are broader inquiries to gather facts, evidence, or information about an event, person, or phenomenon. Interrogations are focused, intense questioning sessions, usually in the context of criminal investigations, aimed at obtaining confessions or specific information.

An investigation involves various methods like research, interviews, surveillance, and analysis. It's a comprehensive approach. Interrogation, however, is a direct, often confrontational method of questioning individuals, typically suspects or witnesses in criminal cases.

Investigations can occur in various settings and involve multiple participants, including investigators, experts, and witnesses. Interrogations are usually conducted in controlled environments, like police stations, and involve a limited number of participants - the interrogator and the subject.
