What is the primary purpose of separating the witnesses during interviews?

• A. To speed up the process
• B. To obtain independent statements and prevent contamination
• C. To confuse the witnesses
• D. To allow collusion

Answer: (B)

Separating witnesses during interviews aims to capture independent recollections before they influence each other. When witnesses discuss the event together, they can unintentionally share details, align timelines, or reinforce memory gaps, which contaminates statements. Interviewing separately preserves each person’s original perceptions and sequencing, making it easier to assess credibility and spot inconsistencies later. Differences between independent accounts can reveal what’s accurate and what might be biased or fabricated, reducing the risk of collusion. That’s why the primary purpose is to obtain independent statements and prevent contamination.
