What type of interview is designed to gather contextual information about an incident, including crucial details such as Who, What, Where, When, How, and Why?

An informational interview is specifically structured to gather pertinent contextual information surrounding an incident. This type of interview focuses on collecting details regarding the who, what, where, when, how, and why of the situation at hand. Such interviews aim to paint a comprehensive picture of the events, often involving individuals who may have witnessed or have knowledge about the circumstances, rather than ones who are being accused of wrongdoing.

In contrast, an interrogation typically involves a more confrontational approach, aimed primarily at obtaining admissions or confessions from a suspect regarding their involvement in an incident. This is different from the goal of gathering contextual information.

A suspect interview is directed towards individuals suspected of involvement in a crime, and while it can collect useful information, its primary focus is often to ascertain the guilt or innocence of the individual.

An evidence interview, though less commonly referred to, would presumably focus on gathering information about physical or digital evidence related to the incident without necessarily addressing the context in the same comprehensive manner as an informational interview.

Thus, the nature of an informational interview makes it the most suitable choice for collecting contextual information about an incident.
