What defines an 'interview' in criminal investigations?

An interview in criminal investigations is defined as a formal conversation with a witness or suspect. This distinction is essential because it emphasizes the structured nature of interviews in the investigative process. During such conversations, investigators aim to gather information, clarify details related to a case, and potentially elicit confessions or admissions from suspects.

Formal interviews are typically conducted under specific protocols that ensure the integrity of the information collected and respect the rights of the individuals involved. This might include taking notes or recording the conversation, and it often occurs in a controlled environment where investigators can monitor the situation closely to ensure the interviewee feels safe and understood.

The other options do not capture the formal and structured nature of interviews in criminal investigations. An informal chat suggests a casual interaction that lacks the seriousness and protocol expected, while discussions between officers typically involve strategy or case discussions rather than direct information gathering from witnesses or suspects. A procedure for prosecuting evidence does not pertain directly to the interviewing process itself, as it relates more to the legal systems used to present information in court. Thus, the definition of an interview is pivotal in understanding how investigators engage with individuals involved in a case.
