Blind verification is defined as:

• A. The independent examination of a friction ridge impression by another qualified latent print examiner who does not know the conclusion of the original examiner.
• B. A re-examination by the same examiner.
• C. Verification performed with the conclusion prior to examination.
• D. A review by the supervisor.

Answer: (D)

Blind verification centers on having an independent check of the initial analysis to avoid bias in the final conclusion. In many labs, the formal verification step is carried out by a supervisor, who reviews the case separately to confirm the findings before reporting. This supervisory review provides an objective second look, adds an official layer of accountability, and helps ensure conclusions are defensible in court.

So, a supervisor’s review fits this definition of blind verification because it introduces a fresh, independent assessment that can validate or challenge the original analysis without being swayed by it. The other options describe scenarios that either involve the same examiner, introduce bias by pre-knowledge of the conclusion, or rely on a second examiner without the supervisory oversight that this context emphasizes.
