Video: How Reliable Are Latent Fingerprint Examiners?

In a new video, Miami-Dade latent print examiner Brian Cerchiai talks about an NIJ-supported study conducted by the Miami-Dade (Florida) Police Department on the accuracy of fingerprint examiners.


The study found that fingerprint examiners make extremely few errors. Even when examiners did not get an independent second opinion about their decisions, they were remarkably accurate. But when decisions were verified by an independent reviewer, examiners had a 0-percent false positive, or incorrect identification, rate and a 3-percent false negative, or missed identification, rate.
