The Brady Materiality Standard, Brandon L. Garrett, Adam M. Gershowitz

Faculty Scholarship

The Brady doctrine requires prosecutors to disclose all favorable and material evidence to the defense. To effectuate that rule, the U.S. Supreme Court has defined materiality as a “reasonable probability” that the evidence would have affected the outcome at trial. But apart from that definition, the Court has resisted offering any further guidance to lower courts. While far too little is known about how Brady materiality claims are actually adjudicated, there is strong evidence that courts often reject Brady claims involving withheld evidence on the grounds that the evidence was not significant enough to be material.

To examine how Brady …

Social Media Participation And Scholarly Success In Law, Julian Nyarko, David E. Pozen

Faculty Scholarship

Using a novel dataset on Twitter activity as well as a novel corpus of law journal publications, this paper examines the impact of social media activity on the scholarly success of U.S. law professors. We find that joining Twitter increases citation counts by an average of 22% per year and improves article placements by up to 10 ranks for law professors, relative to a synthetic control group. These positive returns apply across nearly all classes of scholars and are magnified for those who post frequently about their own work. The identified citation boost would be even larger than 22% if …

Oriented Data-Generating Processes: A Categorization Of Roc Curves, Claude Fluet, Murat C. Mungan

Faculty Scholarship

Decision makers attempting to classify a binary state of the world may commit two types of errors. Even when the two alternative states have equal prior probabilities and when the two types of errors are equally costly, a classification criterion may be chosen which leads to one type of error being committed more frequently than the other, because of asymmetries in the data that informs their decisions. We formalize this possibility through a categorization of data-generating processes (DGPs), which may be ‘oriented’ towards evidence favoring one of the two alternatives, or which may be ‘unoriented’. We identify the shape properties …

Law And Historical Materialism, Jeremy K. Kessler

Faculty Scholarship

Since the financial crisis of 2008, left-leaning legal thought has experienced a renaissance within the American academy. From law and political economy to critical race theory to feminist legal studies to Marxist legal theory, new perspectives have flourished, and marginalized traditions have been revived and revised. These new perspectives and revisionist projects all share an intellectual debt to the critical legal studies (“CLS”) movement of the late 1970s and 1980s. That movement’s critique was focused on functional accounts of law: accounts that understood legal change as primarily responsive to the demands of extralegal social and economic forces. Some of those …

Understanding Processes That Produce Racial Disparities In California Death Sentences: A Review Of The Literature, Catherine M. Grosso, Michael Laurence, Jeffrey A. Fagan

Faculty Scholarship

A robust and extensive body of empirical research, and a rich historical record, documents a recurring and pervasive influence of race in the application of California’s death penalty. This article reviews the legal and social science research to document multiple paths through which institutions and processes produce these racial disparities over many decisions in many cases across four decades. The article reviews relevant literature by decision, institution, or actor and presents key findings. This includes documenting the history of the broad statutory design of the California capital punishment statue. The review also considers research on policing, including the influence of …

Racial Disparities In Crime-Based Removal Proceedings, Emily Ryo, Ian Peacock, Weston Ley, Christopher Levesque

Faculty Scholarship

Whether and to what extent racial minorities experience harsher treatment or face worse outcomes in court are questions of fundamental importance for any justice system. Questions of racial inequality are especially salient in the context of removal proceedings that are triggered by immigrants’ criminal history. Many individuals in crime-based removal proceedings are immigrants of color who face a host of legal disadvantages that are tantamount to double penalties for the same crime for which they have already been punished through the criminal justice system. This Article offers, for the first time, systematic empirical analyses of crime-based removal proceedings decided between …

New Insights On Expert Opinion About Eyewitness Memory Research, Travis M. Seale-Carlisle, Adele Quigley-Mcbride, Jennifer E. F. Teitcher, William E. Crozier, Chad S. Dodson, Brandon L. Garrett

Faculty Scholarship

Experimental psychologists investigating eyewitness memory have periodically gathered their thoughts on a variety of eyewitness memory phenomena. Courts and other stakeholders of eyewitness research rely on the expert opinions reflected in these surveys to make informed decisions. However, the last survey of this sort was published more than 20 years ago, and the science of eyewitness memory has developed since that time. Stakeholders need a current database of expert opinions to make informed decisions. In this article, we provide that update. We surveyed 76 scientists for their opinions on eyewitness memory phenomena. We compared these current expert opinions to expert …

On Critical Geneaology, Bernard E. Harcourt

Faculty Scholarship

Today most critical theorists who deploy history use a genealogical method forged by Nietzsche and Foucault. This genealogical approach now dominates historically inflected critique. But not all genealogical writings today, nor all philosophical debates surrounding genealogy, advance the goals of critical philosophy. It is crucial now that we assess the value of genealogical critiques. The proper metric against which to evaluate such work is whether it contributes to transforming ourselves, others, and society in a valuable way. In this article, I propose that we use the term “critical genealogy” to identify those genealogical practices that positively nourish our activity and, …

The Will To Chaos And Disorder: The Behemoth As A Model Of Political Economy, Bernard E. Harcourt

Faculty Scholarship

The history of political economy is tormented by beasts. The most famous is the Leviathan, the giant serpentine monster that figures in Hobbes’s masterpiece of modern political theory. Robert Fredona and Sophus Reinert spotlight another sea monster, the Kraken, that giant octopus or squid with a particular morphology (i.e., its tentacles) that so fittingly describes the grip of multinational corporations, stateless financial capital, social media, and tech giants today. But there are still other monsters in the bestiary of political economy. In this essay, I highlight the Behemoth, a land monster that captures another critical dimension of political economy: the …

False Accuracy In Criminal Trials: The Limits And Costs Of Cross Examination, Lisa Kern Griffin

Faculty Scholarship

According to the popular culture of criminal trials, skillful cross-examination can reveal the whole “truth” of what happened. In a climactic scene, defense counsel will expose a lying accuser, clear up the statements of a confused eyewitness, or surface the incentives and biases in testimony. Constitutional precedents, evidence theory, and trial procedures all reflect a similar aspiration—that cross-examination performs lie detection and thereby helps to produce accurate outcomes. Although conceptualized as a protection for defendants, cross-examination imposes some unexplored costs on them. Because it focuses on the physical presence of a witness, the current law of confrontation suggests that an …

Liberty, Safety, And Misdemeanor Bail, Brandon L. Garrett, Sandra Guerra Thompson, Dottie Carmichael, David Shi, Songman Kang

Faculty Scholarship

The highest volume of cases in the U.S. criminal system are misdemeanors, and every day, hundreds of thousands of people are detained pretrial in such low-level cases. In policy and in politics, pretrial rules have swung between a focus on protecting constitutional rights and the public safety dangers posed by releasing arrestees. The Supreme Court’s ruling in United States v. Salerno sought to promote a balance between protecting individual due process rights and public safety interests. A central constitutional and pressing policy question is what trade-off exists between pretrial liberty and reoffending. The highest profile jurisdiction to examine that question …

Judging Firearms Evidence, Brandon L. Garrett, Eric Tucker, Nicholas Scurich

Faculty Scholarship

Firearms violence results in hundreds of thousands of criminal investigations each year. To try to identify a culprit, firearms examiners seek to link fired shell casings or bullets from crime scene evidence to a particular firearm. The underlying assumption is that firearms impart unique marks on bullets and cartridge cases, and that trained examiners can identify these marks to determine which were fired by the same gun. For over a hundred years, firearms examiners have testified that they can conclusively identify the source of a bullet or cartridge case. In recent years, however, research scientists have called into question the …

Evaluating Pre-Trial Programs Using Interpretable Machine Learning Matching Algorithms For Causal Inference, Travis Seale-Carlisle, Saksham Jain, Courtney Lee, Caroline Levenson, Swathi Ramprasad, Brandon Garrett, Sudeepa Roy, Cynthia Rudin, Alexander Volfovsky

Faculty Scholarship

After a person is arrested and charged with a crime, they may be released on bail and required to participate in a community supervision program while awaiting trial. These ‘pretrial programs’ are common throughout the United States, but very little research has demonstrated their effectiveness. Researchers have emphasized the need for more rigorous program evaluation methods, which we introduce in this article. We describe a program evaluation pipeline that uses recent interpretable machine learning techniques for observational causal inference, and demonstrate these techniques in a study of a pre-trial program in Durham, North Carolina. Our findings show no evidence that …

The Right To A Glass Box: Rethinking The Use Of Artificial Intelligence In Criminal Justice, Brandon L. Garrett, Cynthia Rudin

Faculty Scholarship

Artificial intelligence (“AI”) increasingly is used to make important decisions that affect individuals and society. As governments and corporations use AI more pervasively, one of the most troubling trends is that developers so often design it to be a “black box.” Designers create AI models too complex for people to understand or they conceal how AI functions. Policymakers and the public increasingly sound alarms about black box AI. A particularly pressing area of concern has been criminal cases, in which a person’s life, liberty, and public safety can be at stake. In the United States and globally, despite concerns that …

The Brady Database, Brandon L. Garrett, Adam M. Gershowitz, Jennifer Teitcher

Faculty Scholarship

The Supreme Court’s landmark ruling in Brady v. Maryland turns sixty this year. The Brady doctrine, which requires the government to disclose favorable and material evidence to the defendant, is one of the most frequently litigated criminal procedure issues. Yet, despite decades of Brady cases in federal and state courts, we still know relatively little about how Brady claims are litigated, adjudicated, and what such claims can tell us about the criminal justice system writ large. Scholars are in the dark about how often Brady violations occur, whether it is primarily the fault of prosecutors or the police, whether violations …

Hydra: Lessons From The World's Largest Darknet Market, Priyanka Goonetilleke, Alex Knorre, Artem Kuriksha

Faculty Scholarship

Research Summary

We present a comprehensive description of Hydra, the largest darknet marketplace in the world until its shutdown in April 2022. We document the main features of Hydra such as dead-drop delivery, feedback and reputation system, escrow, and dispute resolution. Using data scraped from the platform, we quantitatively examine the scale and the structure of the marketplace. We find that it has been highly competitive, geographically covering at least 69% of the Russian population and trading a wide variety of drugs, while also allowing the wholesale trade of drugs and precursors. The dead-drop delivery system used on Hydra was …

Bail And Mental Illness, Samuel Wiseman

Faculty Scholarship

In many parts of the United States, the bail system is strikingly unfair, imposing burdensome, and often unmeetable, financial conditions on pretrial liberty even for low-risk defendants. Reforms that reduce or eliminate cash bail and lower pretrial detention rates have made progress in recent years, but now face growing opposition even in generally progressive jurisdictions such as San Francisco and New York City. One source of this opposition is rising concern about crime—particularly crime associated with the unhoused, who disproportionately suffer from mental illness, including substance abuse disorder. This is not a coincidence, as one effect of a cash-bail system, …

Error Aversions And Due Process, Brandon L. Garrett, Gregory Mitchell

Faculty Scholarship

William Blackstone famously expressed the view that convicting the innocent constitutes a much more serious error than acquitting the guilty. This view is the cornerstone of due process protections for those accused of crimes, giving rise to the presumption of innocence and the high burden of proof required for criminal convictions. While most legal elites share Blackstone’s view, the citizen-jurors tasked with making due process protections a reality do not share the law’s preference for false acquittals over false convictions.

Across multiple national surveys, sampling more than 10,000 people, we find that a majority of Americans views false acquittals and …

Creating Tomorrow’S Change-Makers: Using Alternative Media In The 1l Skills Classroom To Connect Students With Real Practice And Enhance Established Methods For Teaching Appellate Advocacy, Marni Goldstein Caputo, Kathleen Luz

Faculty Scholarship

Fostering that idea of lawyers as change-makers can be difficult in the typical 1L curriculum. The traditional, doctrinal law school classroom typically has a formula comprised of extensive textbook reading, the Socratic classroom, in which that reading is processed in a large group, and, finally, a cumulative, high-stakes exam at the end of the semester.⁶ That formula has largely not changed for decades.⁷ The lawyering skills classroom is often the only outlier from that formula for first-year law students.⁸ Even so, the skills classroom can be formulaic in its own right—introduction of an assignment, classroom instruction regarding …

Andragogy: The Common Thread In The Teaching Of Adults In Colleges Of Education, Criminal Justice, And Health Management, Grant J. Shostak, Larry Acker, Vanessa Vandergraaf

Faculty Scholarship

The Covid-19 pandemic has brought dramatic changes to higher education. Students and educators face challenges never anticipated, including switching classes from on-ground to online and back again, mental fatigue, stress, and burnout. Faculty across disciplines may turn to Andragogy to best teach college students to inform their teaching practices. This paper demonstrates how professors from education, criminal justice, and healthcare management have used andragogical techniques in their classrooms.

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 …

Models Of Bail Reform, Brandon L. Garrett

Faculty Scholarship

Bail reform is an urgent topic in the United States and internationally, but what constitutes reform and how to accomplish reform goals is contested. Jails are a modern epicenter of incarceration, with a stunning growth in American jail populations over the past four decades despite declines in both arrests and crime. As many as sixty percent of the half million people currently in jails have not been convicted but are instead detained pretrial. Prior waves of bail reform produced a system largely reliant on secured bonds, which require up-front cash payments to avoid jail time before trial. More recent reform …

Results Of The Legal Incubator Lawyers' Survey, Aba Standing Committee On The Delivery Of Legal Services, Center For Computer-Assisted Legal Instruction, Luz E. Herrera, Rebecca Sandefur, Briana Morris

Faculty Scholarship

Legal incubators, also known as law firm incubators, in the United States are designed to help lawyers develop and launch law practices while expanding access to underserved populations. Based on business incubator models, legal incubator programs support the creation of new law firms by providing space, mentoring, and training to licensed lawyers. Most of the law firms produced by these legal incubators are solo or small firms that exist as both for profit businesses and nonprofit entities. Since the first legal incubator appeared in 2007, over 70 self-identified legal incubator programs have emerged around the globe.

In 2016, the ABA …

Life Without Parole Sentencing In North Carolina, Brandon L. Garrett, Travis M. Seale-Carlisle, Karima Modjadidi, Kristen M. Renberg

Faculty Scholarship

What explains the puzzle of life without parole (LWOP) sentencing in the United States? In the past two decades, LWOP sentences have reached record highs, with over 50,000 prisoners serving LWOP. Yet during this same period, homicide rates have steadily declined. The U.S. Supreme Court has limited the use of juvenile LWOP in Eighth Amendment rulings. Further, death sentences have steeply declined, reaching record lows. Although research has examined drivers of incarceration patterns for certain sentences, there has been little research on LWOP imposition. To shed light on what might explain the sudden rise of LWOP, we examine characteristics of …

Of Protest And Property: An Essay In Pursuit Of Justice For Breonna Taylor, H. Timothy Lovelace Jr.

Faculty Scholarship

In March 2020, Louisville police officers fatally shot Breanna Taylor in her apartment while executing a no-knock warrant. There was great outrage over the killing of the innocent woman, and Kentucky Attorney General Daniel Cameron led an investigation of the officer-involved shooting.

Activists protested in Louisville after Taylor's killing, and when Cameron's investigation appeared stalled, these activists even conducted a sit-in on Cameron's front lawn. They demanded immediate justice for Taylor. Cameron sharply responded, lecturing the activists on how to achieve justice. He contended that neither trespassing on private property nor escalation in tactics could advance the cause of justice. …

Law Enforcement Organization Relationships With Prosecutors, Daniel C. Richman

Faculty Scholarship

Although police departments and prosecutor’s o􀁽ces must closely collaborate, their organizational roles and networks, and the distinctive perspectives of their personnel, will inevitably and regularly lead to forceful dialogue and disruptive friction. Such friction can occasionally undermine thoughtful deliberation about public safety, the rule of law, and community values. Viewed more broadly, however, these interactions promote just such deliberation, which will become even healthier when the dialogue breaks out of the closed world of criminal justice bureaucracies and includes the public to which these bureaucracies are ultimately responsible. This chapter explores such organizational interactions and their value.
