What is recommended regarding witnesses and subjects at a crime scene?

• A. Interview witnesses immediately at the scene.
• B. Keep witnesses and suspects separated.
• C. Allow witnesses to approach suspects during questioning.
• D. Post witness information publicly immediately.

Answer: (B)

Keeping witnesses and suspects separated preserves the reliability and integrity of the investigation. When witnesses are kept apart from suspects, each account is collected independently, reducing the risk that one witness’s memory or statements are influenced by another, or that a suspect could coach or intimidate a witness. This separation also helps prevent contamination of evidence or memory, making later corroboration and reconstruction of events more accurate. At the scene, procedures support this by securing the area, controlling access, and arranging for separate, neutral interviews rather than combining all interactions in one place. While interviewing witnesses promptly is important, doing so in a way that avoids contact with or exposure to the suspect helps maintain fairness and reduces pressure on witnesses. Publicly posting witness information would expose them to risk and compromise the investigation, so it’s avoided.
