There are significant variations within each discipline of forensic law. Thus, not all fingerprint evidence is equally good, because the true value of the evidence is determined by the quality of the latent fingerprint image. In short, the interpretation of forensic evidence is not infallible. This reality is not always fully appreciated or accepted by many forensic science practitioners, judges, jurors, policymakers, or lawyers and their clients. In this context, it is important to discuss the frye standard and rule 702 of the federal rules of evidence, and the daubert decision and the supreme court’s construction of rule 702.
