How should sensitive evidence be handled to maintain integrity?

• A. Store all copies in an unprotected location.
• B. Minimize handling, maintain chain of custody, secure storage, and document steps.
• C. Allow unrestricted access to evidence for speed.
• D. Delete logs after use.

Answer: (B)

To maintain evidence integrity, you minimize handling, keep a clear chain of custody, secure the storage, and document every step. Minimizing handling reduces the risk of contamination, alteration, or damage to the evidence. The chain of custody is a continuous, verifiable record that shows who has had possession of the item, what was done to it, and when, creating a trace from collection to presentation that helps prove it hasn’t been tampered with. Secure storage means locked, access-controlled spaces with tamper-evident containers and proper labeling, plus environmental controls to prevent degradation. Documenting every action—dates, times, who accessed or handled it, the purpose, transfers, and condition notes—builds a transparent history that supports admissibility and reliability.

Storing evidence in an unprotected location invites loss or tampering; allowing unrestricted access erodes control and increases the risk of unauthorized changes; and deleting logs removes the essential trail that proves the evidence remained intact and appropriately handled.
