Juries and Crime Labs: Correcting the Weak Links in the DNA Chain

Abstract

After a decade of courtroom battles and heated academic debate, the United States has entered an age where the scientific validity of deoxyribonucleic acid (DNA) evidence is not subject to serious dispute. The problem with DNA evidence is no longer one of validity, but one of proficiency. Two confounding variables in the DNA testing process weaken and often destroy DNA's powerfulness and usefulness in the courtroom: crime labs and juries.This Note proposes new and stringent standards for the admissibility of DNA evidence. The admissibility of forensic DNA evidence must be conditioned on its examination by a crime lab governed by uniform national standards. Such governing national standards must encompass every aspect of the forensic process, from chain of custody to DNA testing procedures, in order to ensure the reliability of DNA evidence. Implementing such a comprehensive national standard, however, only represents a first step toward solving the problem of DNA evidence in the courtroom. This step, however, fails to address the second problem facing the effective use of DNA in courtrooms: juries.
