Regarding follow-up when a witness provides a specific time, the recommended follow-up question is 'How did you know it was that time?'

• A. False
• B. Not applicable
• C. It depends on the context
• D. True

Answer: (D)

When a witness provides a specific time, the reliability of that detail hinges on how they know that time. Asking “How did you know it was that time?” prompts the witness to reveal the basis for the timing—whether they checked a clock, watched the moment, looked at a calendar, were told by someone else, or inferred it from another event. This clarifies whether the time is a precise observation, a recalled moment anchored to an external cue, or a rough estimate. Understanding the source helps assess memory accuracy, potential errors (like misreading a clock or reconstructing timing after the fact), and whether corroboration is needed. Because this question directly probes the grounding of the time and improves the credibility of that detail, it is the recommended follow-up.
