What is the appropriate scenario to use a closed-ended question?

Using closed-ended questions is particularly effective in scenarios where a witness fails to provide a clear or complete response. This is because closed-ended questions require a specific response, typically "yes" or "no," or a limited set of options. In situations where the information provided by the witness is vague or insufficient, closed-ended questions can help clarify details and obtain precise information more efficiently.

By guiding the witness with straightforward questions, law enforcement can narrow down the focus and encourage the witness to provide the necessary specifics. This approach can be crucial during investigations, as it helps to establish facts without the potential confusion or ambiguity that can arise from open-ended questions.

While cooperative witnesses might be more amenable to open-ended questions, and having extensive information could lead to follow-up questions that might be open-ended, the necessity for clear and concise answers in circumstances of incomplete responses emphasizes the utility of closed-ended questioning techniques.
