Firearms And Toolmark Error Rates, Susan Vanderplas, Kori Khan, Heike Hofmann, Alicia L. Carriquiry Jan 2022

Firearms And Toolmark Error Rates, Susan Vanderplas, Kori Khan, Heike Hofmann, Alicia L. Carriquiry

Department of Statistics: Faculty Publications

We have outlined several problems with the state of error rate studies on firearm and toolmark examination. Fundamentally, we do not know what the error rate is for these types of comparisons. This is a failure of the scientific study of toolmarks, rather than the examiners themselves, but until this is corrected with multiple studies that meet the criteria described in Section 3, we cannot support the use of this evidence in criminal proceedings.


Forensic Science In Legal Education, Brandon L. Garrett, Glinda S. Cooper, Quinn Beckham Jan 2022

Forensic Science In Legal Education, Brandon L. Garrett, Glinda S. Cooper, Quinn Beckham

Faculty Scholarship

In criminal cases, forensic science reports and expert testimony play an increasingly important role in adjudication. More states now follow a federal reliability standard, following Daubert v. Merrell Dow Pharmaceuticals and Rule 702, which calls upon judges to assess the reliability and validity of such scientific evidence. Little is known about what education law schools provide regarding forensic and scientific evidence or what types of specialized training they receive on scientific methods or evidence. Whether law schools have added forensic science courses to their curricula in recent years was not known. To better understand the answers to those questions, in …


I Am Not Your Felon: Decoding The Trauma, Resilience, And Recovering Mothering Of Formerly Incarcerated Black Women, Jason M. Williams, Zoe Spencer, Sean K. Wilson Nov 2020

I Am Not Your Felon: Decoding The Trauma, Resilience, And Recovering Mothering Of Formerly Incarcerated Black Women, Jason M. Williams, Zoe Spencer, Sean K. Wilson

Department of Justice Studies Faculty Scholarship and Creative Works

Black women are increasingly targets of mass incarceration and reentry. Black feminist writers call attention to scholars’ need to intersectionalize analyses around how Black women interface with state systems and social institutions. This study foregrounds narratives from Black women to understand their plight while navigating reentry through a phenomenological approach. Through semi-structured interviews, narratives are analyzed using critical frameworks that authentically unearths the lived realities of participants. Themes reveal that for Black mothers, reentry can be just as criminalizing as engaging crime itself. These women face dire consequences around their mothering that induce them into tremendous bouts of trauma. Existing …

The Costs And Benefits Of Forensics, Brandon L. Garrett Jan 2020

The Costs And Benefits Of Forensics, Brandon L. Garrett

Faculty Scholarship

Supreme Court Justice Louis Brandeis famously wrote that states can be laboratories for experimentation in law and policy. Disappointingly, however, the actual laboratories that states and local governments run are not a home for experimentation. We do not have adequate information about either the costs or the benefits of forensic testing or allocation of resources. Increased spending and expansion of crime laboratories has perversely accompanied growing backlogs. Poor quality control has resulted in a series of audits and even closures of crime laboratories. In response to these problems, however, some laboratories and some entire states have developed new approaches toward …

Catching Killers With Consumer Genetic Information, Angela Hackstadt Nov 2019

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?


Introduction, Shari S. Diamond, Richard O. Lempert Oct 2018

Introduction, Shari S. Diamond, Richard O. Lempert

Articles

Experts bedeviled the legal system long before seventeenth-century Salem, when the town's good citizens relied on youthful accusers and witchcraft experts to identify the devil's servants in their midst. As in Salem, claims of expertise have often been questioned and objections raised about the bases of expert knowledge. Expertise, then and now, did not have to be based on science; but the importance of science and the testimony of scientific experts has since medieval times been woven into the fabric of the English jurisprudence that Americans inherited. In cases as long ago as 1299 we find examples of courts seeking …


Smoke But No Fire: When Innocent People Are Wrongly Convicted Of Crimes That Never Happened, Jessica S. Henry Apr 2018

Smoke But No Fire: When Innocent People Are Wrongly Convicted Of Crimes That Never Happened, Jessica S. Henry

Department of Justice Studies Faculty Scholarship and Creative Works

Nearly one-third of exonerations involve the wrongful conviction of an innocent person for a crime that never actually happened, such as when the police plant drugs on an innocent person, a scorned lover invents a false accusation, or an expert mislabels a suicide as a murder. Despite the frequency with which no-crime convictions take place, little scholarship has been devoted to the subject. This Article seeks to fill that gap in the literature by exploring no-crime wrongful convictions as a discrete and unique phenomenon within the wrongful convictions universe. This Article considers three main factors that contribute to no-crime wrongful …

Neuroscience In Forensic Contexts: Ethical Concerns, Stephen J. Morse Feb 2017

Neuroscience In Forensic Contexts: Ethical Concerns, Stephen J. Morse

All Faculty Scholarship

This is a chapter in a volume, Ethics Challenges in Forensic Psychiatry and Psychology Practice, edited by Ezra E. H. Griffith, M.D. and to be published by Columbia University Press. The chapter addresses whether the use of new neuroscience techniques, especially non-invasive functional magnetic resonance imaging (fMRI) and the data from studies employing them raise new ethical issues for forensic psychiatrists and psychologists. The implicit thesis throughout is that if the legal questions, the limits of the new techniques and the relevance of neuroscience to law are properly understood, no new ethical issues are raised. A major ethical lapse …


Adjudicating Death: Professionals Or Politicians?, Stephen J. Choi, Mitu Gulati Jan 2017

Adjudicating Death: Professionals Or Politicians?, Stephen J. Choi, Mitu Gulati

Faculty Scholarship

Variation exists in how death examinations take place in the United States. In some counties and states decisions about autopsies and the issuance of death certificates are made by a local coroner who often needs nothing more than a high school diploma to run for election to the job of coroner. In other counties and states, an appointed medical professional performs the death examination. We provide preliminary tests of the difference in performance between death examination offices run by appointed medical professionals compared with elected coroners. We find that death examiner offices in elected coroner states are less likely to …


Brief For Professor Albert E. Scherr As Amicus Curiae In Support Of Petitioner, Albert E. Scherr Feb 2015

Brief For Professor Albert E. Scherr As Amicus Curiae In Support Of Petitioner, Albert E. Scherr

Law Faculty Scholarship

INTRODUCTION AND SUMMARY OF ARGUMENT Professor Scherr agrees with petitioner that review is warranted because the Maryland Court of Appeals decision is erroneous. The Fourth Amendment does not sanction police harvesting of DNA without probable cause and a warrant and without the subject’s knowledge or consent, to be used however the authorities deem appropriate and without restriction. The Maryland Court of Appeals’ decision is contrary to the Supreme Court’s jurisprudence as articulated in the Riley v. California – Maryland v. King – United States v. Jones trilogy. This case fits squarely in the center of the triangle formed by that …


Women As Expert Witnesses: A Review Of The Literature, Tess M. S. Neal Mar 2014

Women As Expert Witnesses: A Review Of The Literature, Tess M. S. Neal

University of Nebraska Public Policy Center: Publications

This review of women’s participation in the legal system as expert witnesses examines the empirical literature on the perceived credibility and persuasiveness of women compared with men experts. The effects of expert gender are complex and sometimes depend on the circumstances of the case. Some studies find no differences, some find favorable effects for women and others for men, and still others find that expert gender interacts with other circumstances of the case. The findings are interpreted through social role theory and the role incongruity theory of prejudice. Future directions for research are identified and implications are considered for attorneys …

Potential Responses To The Melendez-Diaz Line Of Cases, Richard D. Friedman Jan 2011

Potential Responses To The Melendez-Diaz Line Of Cases, Richard D. Friedman

Articles

Criminal prosecution is increasingly dependent on proof of the results of forensic laboratory tests. They are used, for example, to prove that a given substance contains cocaine; the prove what a driver’s blood alcohol content was; and to demonstrate that the DNA profile of some substance found at the crime scene matches that of the accused.

In Melendez-Diaz v. Massachusetts, 129 S.Ct. 2527 (2009), the United States Supreme Court resolved a question that had divided the lower courts in the wake of Crawford v. Washington, 541 U.S. 36 (2004). The Melendez-Diaz Court held by a 5-4 vote that forensic laboratory …


The Science Of Dna Identification: From The Laboratory To The Courtroom (And Beyond), David H. Kaye Jan 2007

The Science Of Dna Identification: From The Laboratory To The Courtroom (And Beyond), David H. Kaye

Journal Articles

This article focuses on sequences of DNA base-pairs, which are becoming increasingly important in the field of law. These DNA sequences are used by forensic scientists to discover evidence such as blood stains, semen, saliva, and hair, and has become highly useful in the courtroom with regard to exonerating the innocent and convicting the guilty. Part I of the article examines how courts may (or may not) admit DNA evidence in court through four phases: uncritical acceptance; serious challenges to analytical methods and statistical interpretation of the results; renewed acceptance of DNA evidence; and acceptance of advance systems of DNA …


Behavioral Genetics Research And Criminal Dna Databanks, David H. Kaye Jan 2006

Behavioral Genetics Research And Criminal Dna Databanks, David H. Kaye

Journal Articles

This article examines the current concerns about whether DNA databases may be used for actions other than to apprehend criminals, such as genetic research, in particular, searching for a "crime gene". Part II considers the perspective that these databases may be useful for research. The information within a DNA sample consists of a limited number of DNA base-pair variations, which are important to identification, but not necessarily to genetic research. However, while it may be difficult to conduct genetic research, it is not impossible. Part III examines state and federal database legislation. There are examples of three states' statutes and …


An Integrated Framework For Modeling And Simulation Of The U.S. Southern Border: A Border Patrol Perspective, Shannon R. Bowling, Ghaith Rabadi, Charles Keating Jan 2006

An Integrated Framework For Modeling And Simulation Of The U.S. Southern Border: A Border Patrol Perspective, Shannon R. Bowling, Ghaith Rabadi, Charles Keating

Engineering Management & Systems Engineering Faculty Publications

Border Security is a complex system consisting of many interrelated components that must function as a whole in order to be effective. The efficacy of border security is dependent on several independent agencies; these include U.S. Customs and Border Patrol (CBP), Immigration and Customs Enforcement (ICE), the Department of Justice (DOJ), state and local law enforcement, and many others. Border security is not only a function of how well each of the agencies perform individually but also how well they interact to accomplish a goal. This paper attempts to model border security from a Border Patrol (BP) perspective using discrete …

After The Dna Wars: Skirmishing With Nrc Ii, Richard O. Lempert Jul 1997

After The Dna Wars: Skirmishing With Nrc Ii, Richard O. Lempert

Articles

This article traces some of the controversies surrounding DNA evidence and argues that although many have been laid to rest by scientific developments confirmed in the National Research Council's second DNA report, there remain several problems which are likely to lead to continued questioning of standard ways prosecutors present DNA evidence. Although much about the report is to be commended, it falls short in several ways, the most important of which is in its support for presenting random match probabilities independent of plausible error rates. The article argues that although one can sympathize with the NRC committee's decision as an …


The Honest Scientist's Guide To Dna Evidence, Richard O. Lempert Jan 1995

The Honest Scientist's Guide To Dna Evidence, Richard O. Lempert

Book Chapters

Thank you for your invitation to participate in the DNA symposium. As you know DNA has never been a prime research focus of mine, and I have been so preoccupied with my own work on ITPT (intertemporal personal transportation) that I thought I must decline. Happily, however, the two projects came together, for I recently had an amazing breakthrough during which by coincidence I stumbled across a book entitled A Century of DNA Testing and holocopied (a fancy form of Xeroxing) the following few pages for you.


The Honest Scientist's Guide To Dna Evidence, Richard O. Lempert Jan 1995

The Honest Scientist's Guide To Dna Evidence, Richard O. Lempert

Articles

The honest scientist recognizes that she herself is a test instrument, and a fallible one at that. Subjectivity inescapably enters into any human endeavor, and should not be denied. DNA testing is rife with subjective elements, no place more so than at the crucial stage of deciding whether a match exists. On the one hand, non-matching extraneous bands may sometimes be properly disregarded and patterns that do not quite meet objective matching criteria may be appropriately regarded as incriminatory matches. On the other hand, band patterns that do meet objective matching criteria may be treated as exonerative depending on how …


Comment: Theory And Practice In Dna Fingerprinting, Richard O. Lempert May 1994

Comment: Theory And Practice In Dna Fingerprinting, Richard O. Lempert

Articles

Throughout her useful paper on DNA identification, Professor Roeder properly attends to both theory and practice. Thus she acknowledges the theoretical soundness of certain criticisms that have been made of the standard paradigm used to evaluate DNA random match probabilities but argues that in practice these criticisms matter little. I am thinking here of the arguments that those cautioning against overweighing DNA evidence have made regarding the undeniable existence of population substructure and its potential implications for independence assumptions supporting the application of the product rule and for the use of convenience samples, such as data garnered from no more …


The Suspect Population And Dna Identification, Richard O. Lempert Sep 1993

The Suspect Population And Dna Identification, Richard O. Lempert

Articles

Forensic DNA analysis typically proceeds by first determining whether alleles (one of two or more alternative forms of a gene) found in DNA apparently left by the perpetrator of a crime at a crime scene (the "evidence sample") match alleles extracted from a sample of the suspected criminal's blood (the "suspect sample"). If alleles drawn from the two sources match, the next step is to provide information about the probative value of the match by estimating the probability that alleles extracted from the blood of some random individual would have matched the alleles in the evidence sample. Thinking in terms …


Dna, Science And The Law: Two Cheers For The Ceiling Principle, Richard O. Lempert Sep 1993

Dna, Science And The Law: Two Cheers For The Ceiling Principle, Richard O. Lempert

Articles

The ceiling principle is an intentionally conservative way of estimating the frequency with which individuals who share particular alleles appear in the general population. It establishes frequencies for each allele by taking random samples of 100 individuals from each of 15 to 20 populations and using the largest frequency with which the allele is found in any of these populations or 5 percent, whichever is larger, as an estimate of the allele's frequency in the population of interest. These frequencies are then multiplied to yield an estimate of the likelihood that a randomly selected person would exhibit the same allelic …


Telling Tales In Court: Trial Procedure And The Story Model, Richard O. Lempert Nov 1991

Telling Tales In Court: Trial Procedure And The Story Model, Richard O. Lempert

Articles

There are three ways in which stories may figure prominently at trials. First, litigants may tell stories to jurors. Not only is there some social science evidence that this happens, but trial lawyers have an instinctive sense that this is what they do. Ask a litigator to describe a current case and she is likely to reply, "Our story is ... " Second, jurors may try to make sense of the evidence they receive by fitting it to some story pattern. If so, the process is likely to feed back on itself. That is, jurors are likely to build a …


Some Caveats Concerning Dna As Criminal Identification Evidence: With Thanks To The Reverend Bayes, Richard O. Lempert Nov 1991

Some Caveats Concerning Dna As Criminal Identification Evidence: With Thanks To The Reverend Bayes, Richard O. Lempert

Articles

The conference panel at which this paper was originally presented was structured along the lines of a debate. The three speakers who were supposed to advocate the use of DNA evidence were labeled, as is customary, Proponents. But those who were supposed to take the negative side were not called Opponents. Rather they were labeled Caveators. I do not know who is responsible for this label, but I think it gets things exactly right. To my mind anyone considering DNA as criminal identification evidence should be a Caveator. The promise and utility of DNA analysis in identifying the perpetrators of …
