What criteria are used to assess the credibility of witnesses and documents during an LRA investigation?

• A. Consistency, corroboration, and plausibility.
• B. Past reliability and independent verification.
• C. Perception bias alone.
• D. Consistency, corroboration, plausibility, perception bias, past reliability, and independent verification.

Answer: (D)

Evaluating credibility in LRA investigations uses a multi-faceted approach. Consistency across statements helps identify contradictions and align with what is already known. Corroboration from other sources or evidence provides independent support for a claimed account. Plausibility checks whether the described events could reasonably occur given the context and known facts. Perception bias recognizes that memory and observation can be influenced by beliefs, expectations, or emotions, so investigators assess how such biases might color recall. Past reliability looks at the witness’s history of providing accurate information in the past. Independent verification involves confirming claims through independent records or third-party sources rather than relying solely on a single account. Together these criteria form a thorough framework for judging credibility of both witnesses and documents, and leaving out any one of them can weaken the assessment. The most comprehensive approach incorporates all six criteria.
