Unreliable Forensic Science, Sarah Ciuffetelli

Quest

The Effectiveness of Forensic Science

Research in progress for CRIJ 1301: Introduction to Criminal Justice

Faculty Mentor: Stefanie LeMaire

Sarah Ciuffetelli uses critical thinking to examine the effectiveness of forensic sciences during criminal investigations. The assignment requires students to find the most prominent scholarly research in forensic sciences and discuss its efficacy. Further, the research leads students to discuss the potential limitations investigators must consider when examining forensic evidence. Lastly, students find at least six scholarly sources to provide an in-depth analysis of the research.

Sarah begins by discussing the history of forensic science and the ever-increasing technology used in …

The Absence Or Misuse Of Statistics In Forensic Science As A Contributor To Wrongful Convictions: From Pattern Matching To Medical Opinions About Child Abuse, Keith A. Findley

Dickinson Law Review (2017-Present)

The new scrutiny that has been applied to the forensic sciences since the emergence of DNA profiling as the gold standard three decades ago has identified numerous concerns about the absence of a solid scientific footing for most disciplines. This article examines one of the lesser-considered problems that afflicts virtually all of the pattern-matching (or “individualization”) disciplines (largely apart from DNA), and even undermines the validity of other forensic disciplines like forensic pathology and medical determinations about child abuse, particularly Shaken Baby Syndrome/Abusive Head Trauma (SBS/AHT). That problem is the absence or misuse of statistics. This article begins by applying …

Forensics’ Fight: A Need For Aggressive Strategies Against Confirmation Bias, Madison Mcgowan

Themis: Research Journal of Justice Studies and Forensic Science

In 2009, the National Academy of Sciences produced a lengthy report illuminating significant weaknesses present within the forensic community. One complex fault found in forensics was conformation bias. Since it is within human nature to make decisions based on contextual information, assumptions, and pre-held opinions, confirmation bias is an issue that will continue to persist. Therefore, stronger efforts must be made to recognize and abate the problem of bias within the field of forensics in order to preserve the notion that forensic science exists to serve principles of both truth and justice. Accordingly, this paper argues for the fight against …

Changing The Culture Of Disclosure And Forensics, Valena Beety

Washington and Lee Law Review Online

This Essay responds to Professor Brandon Garrett’s Constitutional Regulation of Forensic Evidence, and, in particular, his identification of the dire need to change the culture of disclosing forensic evidence. My work on forensics is—similarly to Garrett’s—rooted in both scholarship and litigation of wrongful convictions. From this perspective, I question whether prosecutors fully disclose forensics findings and whether defense attorneys understand these findings and their impact on a client’s case. To clarify forensic findings for the entire courtroom, this Essay suggests increased pre-trial discovery and disclosure of forensic evidence and forensic experts. Forensic analysts largely work in police-governed labs; therefore, …

Ultracrepidarianism In Forensic Science: The Hair Evidence Debacle, David H. Kaye

Washington and Lee Law Review Online

For over 130 years, scientific sleuths have inspected hairs under microscopes. Late in 2012, the FBI, the Innocence Project, and the National Association of Criminal Defense Lawyers joined forces to review thousands of microscopic hair comparisons performed by FBI examiners over several of those decades. The results have been astounding. Based on the first few hundred cases in which hairs were said to match, it appears that examiners exceeded the limits of science in over 90% of their reports or testimony. The disclosure of this statistic has led to charges that the FBI faked an entire field of forensic science, …

A Tale Of Two Sciences, Erin Murphy

Michigan Law Review

It was the best of times, it was the worst of times . .. . So might one describe the contrasting portraits of DNA's ascension in the criminal justice system that are drawn in David Kaye's The Double Helix and the Law of Evidence and Sheldon Krimsky and Tania Simoncelli's Genetic Justice: DNA Data Banks, Criminal Investigations, and Civil Liberties. For Kaye, the double helix stands as the icon of twenty-first-century achievement, a science menaced primarily by the dolts (lawyers, judges, and the occasional analyst) who misuse it. For Krimsky and Simoncelli, DNA is a seductive forensic tool that is …

The Individualization Fallacy In Forensic Science Evidence, Michael J. Saks, Jonathan J. Koehler

Vanderbilt Law Review

Forensic identification science involves two fundamental steps. The first step is to compare a questioned item of evidence to an exemplar from a known source and judge whether they appear so alike that they can be said to match. The second step is to assess the meaning of that reported match: What is the probability that the questioned and the known originated from the same source?

Different risks of error are present at each step. The risk of error in the first step is that a reported match between a questioned and a known sample might not really match. Even …
