What investigative technique involves obtaining cooperation from subjects?

• A. Undercover surveillance
• B. Interviewing
• C. Wiretapping
• D. Report analysis

Answer: (B)

The investigative technique of interviewing is clearly focused on obtaining information by engaging directly with individuals who may have knowledge pertinent to the investigation. This method is effective because it invites cooperation from the subjects, allowing interviewers to gather valuable insights, clarify facts, and potentially elicit confessions or leads. Through effective questioning and rapport-building, agents can enhance the likelihood that subjects will share truthful and relevant information, which is crucial for advancing an investigation.

In contrast, undercover surveillance and wiretapping are more intrusive methods that involve observing or monitoring individuals without their knowledge, which does not rely on cooperation. Report analysis usually involves reviewing existing documents and records for relevant information, and it does not involve direct interaction with subjects. Thus, the essence of interviewing as a cooperative technique is what sets it apart as the correct answer.
