What does "double-locking" handcuffs accomplish?

• A. It prevents the cuffs from tightening accidentally, reducing injury risk and enhancing safety.
• B. It makes the cuffs harder to remove.
• C. It increases the risk of injury.
• D. It has no effect on safety.

Answer: (A)

Double-locking is a safety feature that adds a secondary lock to the handcuff mechanism so the cuff cannot tighten any further. The key benefit is preventing the cuff from cinching tighter if the detainee pulls or wriggles, which lowers the chance of nerve damage, reduced blood flow, or other injury to the wrist. Officers can still unlock and remove the cuffs with the proper key, and releasing the double lock is part of the normal procedure. Because of this, it actually improves safety rather than harming it. The other statements don’t fit because removal difficulty isn’t the intended effect, and it doesn’t increase injury or have no safety impact.
