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 …

"Waiving" Goodbye To Rights: Plea Bargaining And The Defense Dilemma Of Competent Representation, Jane Moriarty

Jane Campbell Moriarty

The proposed amendments to the ABA Criminal Justice Standards for Prosecutors and Defense Lawyers (“Proposed Standards”) address a number of problematic issues related to the roles of both prosecutors and defense attorneys. This Symposium Article considers waiver of rights in the context of the Standards, focusing on guilty pleas and the so-called “preconditions” that prosecutors generally require before even entertaining the defendant’s proffer, colloquially termed “Queen for a Day” agreements It reviews the development in the law since 1993, the changes in the practice since that time, and the proposed changes to the Standards. The article focuses on the complex …

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 …

“Misconvictions,” Science And The Ministers Of Justice, Jane Campbell Moriarty

Jane Campbell Moriarty

DNA evidence has exonerated over two hundred wrongfully convicted defendants in the last several years, providing insights into the causes of such convictions. One such cause, faulty scientific evidence, is a focus of this article. For decades, many have written about the prevalence of and reasons for wrongful convictions --what I have termed “misconvictions.” A few reasons support the coinage “misconvictions”: the miscarriage of justice when an innocent person is convicted; the mistakes involved in the prosecution and trial of the case; the mistaken identification that may have occurred; and finally, the recognition that all wrongful convictions are a missed …

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 …
