Which term describes the process of documenting who handled evidence and any changes made to it?

• A. Civil liability
• B. Chain of custody
• C. Classification
• D. Command presence

Answer: (B)

The key concept is chain of custody—the documented, unbroken trail of who has handled the evidence, when, where it’s stored, and every transfer or change in its condition. This record keeps the evidence’s integrity intact and shows it hasn’t been tampered with from collection to presentation in court. It includes logs of who collected it, dates and times, storage locations, seals on containers, and any alterations or analyses performed. Having a clear chain of custody is essential for admissibility, because gaps or irregularities can cast doubt on the evidence’s reliability. In real-world practice, items are collected, sealed, labeled, and logged at the scene, transported with custody records, and then logged again at each custody point in the lab or during storage. Other terms describe different concepts—civil liability concerns legal responsibility for damages, classification is about sorting items, and command presence refers to an officer’s demeanor and leadership at a scene.
