Should witnesses be interviewed separately?

• A. Yes, This Prevents Collaboration
• B. No, They Can Be Questioned Together
• C. Only If They Agree
• D. Never Interview Witnesses

Answer: (A)

Separating witnesses for interviews preserves the independence of each account. When witnesses are interviewed together, they can influence each other—memory can be swayed, details can be aligned, and pressure from others can shape what is said. Conducting separate interviews lets each person describe what they observed in their own words, making it easier to spot inconsistencies and judge credibility. It also reduces the risk of collusion or coercion between witnesses. While there are occasional reasons to conduct a joint interview, the default approach is to interview separately because this prevents collaboration and maintains the integrity of the testimony.
