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 …

No Longer Innocent Until Proven Guilty: How Ohio Violates The Fourth Amendment Through Familial Dna Searches Of Felony Arrestees, Jordan Mason

Cleveland State Law Review

In 2013, the United States Supreme Court legalized DNA collection of all felony arrestees upon arrest through its decision in Maryland v. King. Since then, the State of Ohio has broadened the use of arrestee DNA by subjecting it to familial DNA searches. Ohio’s practice of conducting familial DNA searches of arrestee DNA violates the Fourth Amendment because arrestees have a reasonable expectation of privacy in the information that is extracted from a familial DNA search and it fails both the totality of the circumstances and the special needs tests. Further, these tests go against the intention of the …

Catching Killers With Consumer Genetic Information, Angela Hackstadt

University Libraries Faculty Scholarship

In April 2018, Joseph James D'Angelo was arrested as a suspect in the Golden State Killer case. DNA evidence collected at a 1980 crime scene finally shed light on the murderer's identity in early 2018 when investigators turned to GEDMatch, a service that allows users to upload and share DNA data obtained from consumer genetic tests. Consumer genetic testing, DNA collection, and familial DNA searching all raise ethical and privacy concerns. If investigators are using genetic genealogy to solve cold cases, where does that leave consumers?

The First Amendment Case For Public Access To Secret Algorithms Used In Criminal Trials, Vera Eidelman

Georgia State University Law Review

As this Article sets forth, once a computerized algorithm is used by the government, constitutional rights may attach. And, at the very least, those rights require that algorithms used by the government as evidence in criminal trials be made available—both to litigants and the public. Scholars have discussed how the government’s refusal to disclose such algorithms runs afoul of defendants’ constitutional rights, but few have considered the public’s interest in these algorithms—or the widespread impact that public disclosure and auditing could have on ensuring their quality.

This Article aims to add to that discussion by setting forth a theory of …

Deploying The Secret Police: The Use Of Algorithms In The Criminal Justice System, Jessica Gabel Cino

Georgia State University Law Review

Algorithms saturate our lives today; from curated song lists to recommending “friends” and news feeds, they factor into some of the most human aspects of decision-making, tapping into preferences based on an ever-growing amount of data. Regardless of whether the algorithm pertains to routing you around traffic jams or finding your next dinner, there is little regulation and even less transparency regarding just how these algorithms work. Paralleling this societal adoption, the criminal justice system now employs algorithms in some of the most important aspects of investigation and decision-making.

The lack of oversight is abundantly apparent in the criminal justice …

The Technologies Of Race: Big Data, Privacy And The New Racial Bioethics, Christian Sundquist

Articles

Advancements in genetic technology have resurrected long discarded conceptualizations of “race” as a biological reality. The rise of modern biological race thinking – as evidenced in health disparity research, personal genomics, DNA criminal forensics, and bio-databanking - not only is scientifically unsound but portends the future normalization of racial inequality. This Article articulates a constitutional theory of shared humanity, rooted in the substantive due process doctrine and Ninth Amendment, to counter the socio-legal acceptance of modern genetic racial differentiation. It argues that state actions that rely on biological racial distinctions undermine the essential personhood of individuals subjected to such taxonomies, …

The Unintended Consequences Of California Proposition 47: Reducing Law Enforcement’S Ability To Solve Serious, Violent Crimes, Shelby Kail

Pepperdine Law Review

For many years, DNA databases have helped solve countless serious, violent crimes by connecting low-level offenders to unsolved crimes. Because the passage of Proposition 47 reduced several low-level crimes to misdemeanors, which do not qualify for DNA sample collection, Proposition 47 has severely limited law enforcement’s ability to solve serious, violent crimes through California’s DNA database and reliable DNA evidence. This powerful law enforcement tool must be preserved to prevent additional crimes from being committed, to exonerate the innocent, and to provide victims with closure through conviction of their assailants or offenders. Proposition 47’s unintended consequences have led to devastating …

Adjudicated Juveniles And Collateral Relief, Joshua A. Tepfer, Laura H. Nirider

Maine Law Review

Collateral relief is a vital part of the American criminal justice system. By filing post-conviction petitions after the close of direct appeal, defendants can raise claims based on evidence outside the record that was not known or available at the time of trial. One common use of post-conviction relief is to file a claim related to a previously unknown constitutional violation that occurred at trial, such as ineffective assistance of counsel. If a defendant’s trial attorney performed ineffectively by failing to call, for instance, an alibi witness, then that omission is unlikely to be reflected in the trial record—but in …

Innocent Suffering: The Unavailability Of Post-Conviction Relief In Virginia Courts, Kaitlyn Potter

University of Richmond Law Review

This comment examines actual innocence in Virginia: the progress it has made, the problems it still faces, and the possibilities for reform. Part I addresses past reform to the system, spurred by the shocking tales of Thomas Haynesworth and others. Part II identifies three of the most prevalent systemic challenges marring Virginia's justice system: (1) flawed scientific evidence; (2) the premature destruction of evidence; and (3) false confessions and guilty pleas. Part III suggests ways in which Virginia can, and should, address these challenges to ensure that the justice system is actually serving justice.

'False But Highly Persuasive:' How Wrong Were The Probability Estimates In Mcdaniel V. Brown?, David H. Kaye

David Kaye

In McDaniel v. Brown, the Supreme Court will review the use of DNA evidence in a 1994 trial for sexual assault and attempted murder. The Court granted certiorari to consider two procedural issues - the standard of federal postconviction review of a state jury verdict for sufficiency of the evidence, and the district court's decision to allow the prisoner to supplement the record of trials, appeals, and state postconviction proceedings with a geneticist's letter twelve years after the trial.

This essay clarifies the nature and extent of the errors in the presentation of the DNA evidence in Brown. It questions …

Decision Making And The Law: Truth Barriers, Jonathan J. Koehler, John B. Meixner Jr.

Scholarly Works

Reaching an accurate outcome is a central goal of the American trial. But structural features of the legal system, in combination with the cognitive shortcomings of legal actors, hinder the search for truth. Regarding the legal system, various rules and policies restrict decision makers’ access to evidence, violate the laws of probability, and limit the evidentiary concerns that may be considered on appeal. Regarding legal actors, informational deficits (particularly regarding scientific and statistical evidence) and cognitive biases of police investigators, witnesses (lay and expert), attorneys, judges, and jurors pose serious obstacles. We conclude by suggesting that research in judgment and …

Visualizing Dna Proof, Nicholas L. Georgakopoulos

Nicholas L Georgakopoulos

DNA proof inherently involves the use of probability theory, which is often counterintuitive. Visual depictions of probability theory, however, can clarify the analysis and make it tractable. A DNA hit from a large database is a notoriously difficult probabi­li­ty theory issue, yet the visuals should enable courts and juries to handle it. The Puckett facts are an example of a general approach: A search in a large DNA database produces a hit for a cold crime from 1972 San Francisco. Probability theory allows us to process the probabilities that someone else in the database, someone not in the database, or …

Dna Storage Banks: The Importance Of Preserving Dna Evidence To Allow For Transparency And The Preservation Of Justice, Cristina Martin

Chicago-Kent Law Review

What is the duty to preserve information in today’s society? In order for humanity to evolve, change and flourish in the future, society needs to preserve its information from the past. In the criminal justice field, preservation of evidence has special significance. DNA evidence in particular has become a helpful aid for innocent defendants who have been improperly imprisoned. Over the past twenty years, the number of exonerations of imprisoned criminal defendants has increased dramatically. With the advancement of technology, old, previously untestable or improperly tested DNA evidence will need to be retested. However, most states do not have proper …

Statistics In The Jury Box: How Jurors Respond To Mitochondrial Dna Match Probabilities, David H. Kaye, Valerie P. Hans, B. Michael Dann, Erin J. Farley, Stephanie Albertson

Valerie P. Hans

This article describes parts of an unusually realistic experiment on the comprehension of expert testimony on mitochondrial DNA (mtDNA) sequencing in a criminal trial for robbery. Specifically, we examine how jurors who responded to summonses for jury duty evaluated portions of videotaped testimony involving probabilities and statistics. Although some jurors showed susceptibility to classic fallacies in interpreting conditional probabilities, the jurors as a whole were not overwhelmed by a 99.98% exclusion probability that the prosecution presented. Cognitive errors favoring the defense were more prevalent than ones favoring the prosecution. These findings lend scant support to the legal argument that mtDNA …

Rapid Dna Testing, Robert M. Sanger

Robert M. Sanger

In 2010, the FBI began the process of encouraging the development of Rapid DNA testing. Rapid DNA testing involves a fully automated process of developing a “short tandem repeat” (STR) profile from a reference sample. The process consists of automated extraction, amplification, separation, detection and allele calling without human intervention. In other words, it is a quick, hands free method of obtaining a DNA profile.

In this article we will look at this new and expanding area of scientific technology. We will also look at the efforts to regulate it and maintain appropriate scientific standards as well as the issues …

Dna By The Entirety, Natalie Ram

All Faculty Scholarship

The law fails to accommodate the inconvenient fact that an individual’s identifiable genetic information is involuntarily and immutably shared with her close genetic relatives. Legal institutions have established that individuals have a cognizable interest in controlling genetic information that is identifying to them. The Supreme Court recognized in Maryland v. King that the Fourth Amendment is implicated when arrestees’ DNA is analyzed, and the Genetic Information Nondiscrimination Act protects individuals from genetic discrimination in the employment and health-insurance markets. But genetic information is not like other forms of private or personal information because it is shared — immutably and involuntarily …

Forensic Evidence And The Court Of Appeal For England And Wales, Lissa Griffin

Elisabeth Haub School of Law Faculty Publications

The Criminal Division of the Court of Appeal has extensively analyzed the role of forensic evidence. In doing so, the court has grappled with the admissibility and reliability of a broad range of forensic evidence, from DNA and computer forensics to medical and psychological proof, to more outlying subjects like facial mapping, fiber analysis, or voice identification. The court has analyzed these subjects from two perspectives: the admissibility of such evidence in the lower courts and the admissibility of such evidence as fresh evidence on appeal. In both contexts, the court has taken a practical approach to admitting forensic proof …

Wrongful Convictions And Upstream Reform In The Criminal Justice System, Kate Kruse

Faculty Scholarship

This Article explores the viability of upstream criminal justice reforms within the context of an adversary and procedural system of criminal justice, focusing on reforms in eyewitness identification procedures. Mistaken eyewitness identification evidence is often cited as the leading cause of wrongful convictions in the United States. Eyewitness identification reforms have also been the most developed upstream efforts to grow out of the innocence movement. The success and limitation of upstream reform in eyewitness identification shed light on the efficacy of upstream criminal justice system reform more generally, as well as in areas that are less developed, such as the …

The Banality Of Wrongful Executions, Brandon L. Garrett

Michigan Law Review

What is so haunting about the known wrongful convictions is that those cases are the tip of the iceberg. Untold numbers of unnoticed errors may send the innocent to prison — and to the death chamber. That is why I recommend to readers a trilogy of fascinating new books that peer deeper into this larger but murkier problem. Outside the rarified group of highly publicized exonerations, which have themselves done much to attract attention to the causes of wrongful convictions, errors may be so mundane that no one notices them unless an outsider plucks a case from darkness and holds …

Juror Typologies And Dna Comprehension:Who Benefits From Jury Trial Innovations?, Mari Sakiyama, Joel D. Lieberman

Graduate Research Symposium (GCUA) (2010 - 2017)

When DNA evidence is presented in the courtroom, it is typically accompanied by complex testimony conveying information such as the method of generating population frequencies, match criteria and probabilities, as well as laboratory errors and error rates. Although this evidence may have high probative value, the legal community has expressed growing concern regarding jurors’ ability to comprehend it. However, courts have implemented a variety of jury trial innovations to facilitate jurors’ ability to process complex information. Although these innovations may have a positive effect on comprehension of complex trial evidence, it is unclear whether some jurors are more likely to …

The Piranha Is As Deadly As The Shark: A Case For The Limitation On Deceptive Practices In Dna Collection, Brett A. Bauman

Brett A Bauman

Police deception tactics are utilized throughout the United States as a way to catch unsuspecting criminals. Although criticized in many respects, most deceptive police techniques are not only legal, but are actually encouraged. DNA collection and analysis is no exception—techniques are frequently used by law enforcement officers in an attempt to collect a suspect’s genetic specimen in the interest of solving crimes. While law enforcement officers typically have the best interests of society in mind, the current practices employed by officers to collect suspects’ DNA violate the Fourth Amendment. The Fourth Amendment provides protection against unreasonable searches and seizures, and …

Defying Dna: Rethinking The Role Of The Jury In An Age Of Scientific Proof Of Innocence, Andrea L. Roth

Andrea L Roth

In 1946, public outrage erupted after a jury ordered Charlie Chaplin to support a child who, according to apparently definitive blood tests, was not his. Half a century later, juries have again defied apparently definitive evidence of innocence, finding criminal defendants guilty based on a confession or eyewitness notwithstanding exculpatory DNA test results. One might expect judges in such cases to direct an acquittal, on grounds that the evidence is legally insufficient because no rational juror could find guilt beyond a reasonable doubt. Yet few if any do. Instead, courts defer to juries when they form an actual belief in …

Factually Innocent Without Dna? An Analysis Of Utah's Factual Innocence Statute, Nic Caine

Utah OnLaw: The Utah Law Review Online Supplement

Since 1989, DNA evidence has fueled the innocence movement, helping hundreds prove their innocence and obtain freedom. DNA technology has been an invaluable development for the innocence movement, and DNA technology will continue to advance and improve in the future. DNA evidence is not available in the majority of cases, however, and many believe that DNA exonerations will eventually diminish as DNA analysis becomes more widely available. Furthermore, “for every DNA exoneree there are hundreds if not over a thousand wrongfully convicted defendants whose cases do not contain biological evidence that could prove innocence.”150 It is time for other states …
