Forensic Science: Why No Research?, Paul C. Giannelli
Forensic Science: Why No Research?, Paul C. Giannelli
Faculty Publications
The National Academy of Sciences ground-breaking report on forensic science – Strengthening Forensic Science in the United States: A Path Forward – raised numerous issues. One dominant theme that runs throughout the Report is the failure of some forensic science disciplines to comport with fundamental scientific principles – in particular, to support claims with empirical research. The Report observed that “some forensic science disciplines are supported by little rigorous systematic research to validate the discipline’s basic premises and techniques. There is no evident reason why such research cannot be conducted.”
The Report went on to identify fingerprint examinations, firearms (ballistics) …
Adverse Inference About Adverse Inferences: Restructuring Juridical Roles For Responding To Evidence Tampering By Parties To Litigation, Dale A. Nance
Adverse Inference About Adverse Inferences: Restructuring Juridical Roles For Responding To Evidence Tampering By Parties To Litigation, Dale A. Nance
Faculty Publications
For at least two centuries, Anglo-American courts have responded to a party's evidence tampering by allowing the opponent to argue to jurors that they should draw an adverse inference against the offending party in deciding the merits of the case. This Article argues that the use of such inferences, and invitations to draw them, should be radically curtailed, not only because of the ambiguities and risks of prejudice that such inferences entail, but more importantly because they reflect and contribute to a confusion of roles in which the jury is enlisted to participate in the management of the pre-trial conduct …

Comparative Bullet Lead Analysis: A Retrospective, Paul C. Giannelli
Faculty Publications
For over thirty years, FBI experts testified about comparative bullet lead analysis (CBLA), a technique that was first used in the investigation into President Kennedy’s assassination. CBLA compares trace chemicals found in bullets at crime scenes with ammunition found in the possession of a suspect. This technique was used by the FBI when firearms (“ballistics”) identification could not be employed – for example, if the weapon was not recovered or the bullet was too mutilated to compare striations. Although the FBI eventually ceased using CBLA, the Bureau’s conduct in first employing the technique and then defending it after it was …
Scientific Fraud, Paul C. Giannelli
Scientific Fraud, Paul C. Giannelli
Faculty Publications
Although scientific fraud is rare, when it occurs, it needs to be identified and documented. This article discusses two of the most notorious cases in forensic science. Part I focuses on the misconduct of Fred Zain, a serologist with the West Virginia State Police crime laboratory and later with the County Medical Examiner’s laboratory in San Antonio, Texas. Part II examines the misconduct of Joyce Gilchrist, a forensic examiner with the Oklahoma City Police Department.

Independent Crime Laboratories: The Problem Of Motivational And Cognitive Bias, Paul C. Giannelli
Independent Crime Laboratories: The Problem Of Motivational And Cognitive Bias, Paul C. Giannelli
Faculty Publications
One of the most controversial recommendations in the National Academy of Sciences report on forensic science — Strengthening Forensic Science in the United States: The Path Forward — concerns the removal of crime laboratories from the administrative control of law enforcement agencies. For decades scholars have commented on the “inbred bias of crime laboratories affiliated with law enforcement agencies.” Some commentators have proposed independent laboratories as the remedy for this problem, and in 22, the Illinois Governor’s Commission on Capital Punishment proposed the establishment of an independent state crime laboratory. This essay documents the problems that triggered the NAS Report’s …
