Brain Trauma, Pet Scans And Forensic Complexity, Jane Moriarty, Daniel Langleben, James Provenzale

Jane Campbell Moriarty

Positron Emission Tomography (PET) is a medical imaging technique that can be used to show brain function. Courts have admitted PET scan evidence in cases involving brain damage, injury, toxic exposure, or illness ("brain trauma") and to support claims of diminished cognitive abilities and impulse control. Despite the limited data on the relationships between PET, brain trauma and behavior, many courts admit PET scan evidence without much critical analysis. This article examines the use of PET as proof of functional impairment and justification of abnormal behavior by explaining its diagnostic use and limitations, the limited support for claims of its …

Using Brain Imaging For Lie Detection: Where Science, Law, And Policy Collide, Daniel D. Langleben, Jane Campbell Moriarty

Jane Campbell Moriarty

Progress in the use of functional magnetic resonance imaging (fMRI) of the brain to differentiate lying from truth-telling has created an expectation of a breakthrough in the search for objective methods of lie detection. In the last few years, litigants have attempted to introduce fMRI-based lie detection evidence in courts. Both the science and its possible use as courtroom evidence have spawned much scholarly discussion. This article contributes to the interdisciplinary debate by identifying the missing pieces of the scientific puzzle that need to be completed if fMRI-based lie detection is to meet the standards of either legal reliability or …

Will History Be Servitude?: The Nas Report On Forensic Science And The Rule Of The Judiciary, Jane Moriarty

Jane Campbell Moriarty

For several decades, the prosecution and its witnesses have maintained that despite little research and virtually no standards, they can match a fingerprint, handwriting, bullet and bullet cartridge, hair, dental imprint, footprint, tire track, or even a lip print to its unique source (collectively, “individualization evidence”). Not only can they match it, they claim, they can do so often without any error rate. In the last few decades, with the help of lawyers and academics, litigants have challenged the underlying reliability of individualization evidence. Scholars in various disciplines have written about the startling state of individualization evidence, including its lack …

Neuroscience, Law & Government: Foreword To The Symposium, Jane Moriarty

Jane Campbell Moriarty

The legal and legislative systems have begun to rely on neuroscience in various types of decision-making. Without question, the relationship between the disciplines will become more enmeshed as more data is generated by neuroscientists. Are we ready for this potential sea change that will be both rich and strange?

Visions Of Deception: Neuroimaging And The Search For Evidential Truth, Jane Moriarty

Jane Campbell Moriarty

The use of science in the search for truth poses consistent evidentiary problems of definition, causation, validity, accuracy, inferential conclusions unsupported by data, and real-world complications. And these evidentiary problems may well be implicated in the forensic use of neuroimages of deception. This article first briefly describes the various types of neuroimaging used to detect deception and describes some of the specific criticisms that have been leveled at the science. Second, the article outlines the standards governing admissibility and explains why the research to date does not yet meet any recognized standards of admissibility. Third, and finally, the article suggests …

Flickering Admissibility: Neuroimaging Evidence In The U.S. Courts, Jane Moriarty

Jane Campbell Moriarty

This article explores the admissibility of neuroimaging evidence in U.S. courts, recognizing various trends in decisions about such evidence. While courts have routinely admitted some neuroimages, such as CT scans and MRI, as proof of trauma and disease, they have been more circumspect about admitting the PET and SPECT scans and fMRI evidence. With the latter technologies, courts have often expressed reservations about what can be inferred from the images. Moreover, courts seem unwilling to find neuroimaging sufficient to prove either insanity or incompetency, but are relatively lenient about admitting neuroimages in death penalty hearings. Some claim that fMRI and …

Symposium Foreward: Daubert, Innocence, And The Future Of Forensic Science, Jane Moriarty

Jane Campbell Moriarty

The years since Daubert have not been kind to those seeking to challenge prosecutorial expert evidence, as many of the Symposium authors recognize. After two decades of trying to convince courts that there is no empirical basis for handwriting identification testimony declaring a match between two samples, Michael Risinger claims to be packing his bags and leaving the island until there is a more conducive climate for examining the reliability problems.

Forensic Science: Grand Goals, Tragic Flaws, And Judicial Gatekeeping, Jane Campbell Moriarty

Jane Campbell Moriarty

In the last decade, a number of scientists have published articles and testified in court, explaining the ways in which they believe that some of the forensic sciences do not meet reliability standards and that laboratories make errors. The explosion of exonerations resulting from DNA technology has raised questions about the accuracy of many forensic sciences and the quality of some laboratory testing. A substantial number of these defendants can point to erroneous forensic science as a contributing cause of their wrongful convictions. In the courts, increasingly, the parties have substantial and serious disagreements about the quality of forensic science. …

Wonders Of The Invisible World: Prosecutorial Syndrome And Profile Evidence In The Salem Witchcraft Trials, Jane Campbell Moriarty

Jane Campbell Moriarty

The primary aims of this Article are to deconstruct the evidence from the Salem witchcraft trials and to determine whether those prosecutions relied upon syndrome and profile evidence, and whether such evidence played a substantial role in the convictions. The secondary aim is to determine whether modern cases employ evidentiary methods sufficiently similar to the Salem cases such that we should reconsider prosecutorial syndrome and profile evidence. This Article concludes that prosecutorial syndrome evidence and, to a lesser degree, prosecutorial profile evidence, were relied upon in the Salem cases and were important to the convictions. Moreover, in modern cases, which …
