What is the Difference Between Investigation and Interrogation?

The main difference between investigation and interrogation lies in their purpose and approach. Here are the key distinctions between the two:

• Investigation: This is a comprehensive process that involves obtaining information, analyzing evidence, and conducting inquiries to identify facts and verify the accuracy of a case. It is a systematic examination and research process aimed at discovering facts and gathering evidence. Investigation includes activities such as questioning witnesses, collecting evidence, and utilizing scientific methods. It is an overarching concept that encompasses various components, including interrogation.
• Interrogation: This is a conversational process between two or more people, in which questions are asked to gain information. In the context of criminal cases, interrogation refers to the verbal questioning of a suspect by law enforcement authorities for the purpose of obtaining a confession or clarifying specific details related to the crime. It is a more controlled and focused approach compared to the broader scope of an investigation.

In summary, investigation is the overarching process of discovering facts and gathering evidence, while interrogation is one component of that process, specifically focused on questioning suspects to obtain confessions or clarify details related to the crime.
