Panel A: Fingerprint Evidence Reliability and Validity in the Courtroom

Abstract

Abstract

This study focuses on the reliability and validity of fingerprint evidence, which in the courtroom, has been used as a defining factor in convictions, based on “expert” opinion. The key issue in refuting the evidence is confirmation bias because of pressure on the forensic scientists. The data focus investigates cases where individuals were convicted on fingerprint evidence that were later overturned based on DNA evidence. The factors associated with reliability include DNA science (which has a high-reliability reputation) versus fingerprint interpretation (which has been questioned owing to human error). The study concludes that DNA evidence over-rides the fingerprint approach, but that fingerprinting still remains a valuable tool in the investigating process.
