Hearsay In High Definition: Body-Worn Cameras And The Future Of Intimate Partner Violence Prosecutions, Kenechukwu Okocha

Working Papers

Technological advances in documenting police encounters with the public have outpaced evidentiary hearsay rules. Specifically, the rapid adoption of body-worn cameras (BWCs), fueled by racial justice and police reform advocates, has produced previously unavailable, vivid, and timely recordings of IPV victims’ accounts of abuse. Unfortunately, state and federal rules governing hearsay often prevent juries from considering these out-of-court statements. Such restrictions carry particular force in IPV cases, where victims frequently recant or decline to testify at trial due to abuser manipulation or distrust of the criminal justice system.

Courts and legislatures have eased some evidentiary restrictions in IPV cases in …

Predicting Less, Understanding More: Shifting The Use Of Machine Learning From Individual Prediction To Structural Insights In Systems That Affect Children And Families, Amanda J. Fairchild, Joshua Gupta-Kagan, Andrew Barclay

Faculty Scholarship

Machine learning algorithms have been deeply embedded across domains, valued for their capacity to analyze large-scale data and to support a range of descriptive and predictive tasks. Despite their versatility, most applications to date have focused on individual-level prediction at the expense of broader structural insights. This paper shifts that focus by using comprehensive demographic, juvenile justice, and other key data from child-serving agencies in one southern state to examine how juvenile and family court intake structures shape case outcomes in delinquency referrals. Specifically, we combine machine learning algorithms with a doubly robust, potential outcomes-based modeling procedure to estimate the …

Stafford V. State [State Of Nevada], 142 Nev. Adv. Op. 59 (Aug. 27, 2026), Giselle Garcia-Contreras

Nevada Supreme Court Summaries

Stafford v. State holds that an in-custody defendant’s failure to appear at a hearing does not relieve the State of its plea agreement obligations, as the State controls the defendant’s ability to appear.

Law Enforcement With Rent Dissipation, Murat C. Mungan, J. Shahar Dillbary

Faculty Scholarship

We consider a framework which brings together losses arising from rent-dissipation and the workhorse model of law enforcement. Governmental actors engage in a contest to share the proceeds from the enforcement of the law through monetary fines, which leads to rent-dissipation. This causes monetary sanctions to be costly, rendering the model used for studying nonmonetary sanctions a better fit for their analysis. The effect of rent-dissipation on optimal sanctions is directly related to the sanction elasticity of offenses measured at the classic optimum (i.e., where the expected sanction equals the direct harm from the offense). When offenses are inelastic, the …

Off-Label Neuroimaging, Jane C. Moriarty

Law Faculty Publications

The growth of neuroimaging evidence in the courtroom is consistent with the increased reliance on technical and machine-based specialties at trial. Litigants routinely seek to introduce neuroimaging evidence in both civil and criminal trials to supplement traditional medical, psychiatric, and psychological opinion testimony. A substantial portion of neuroimaging evidence is still in the developmental stage—what I term “off-label neuroimaging.” Unsurprisingly, evaluating the reliability of developing neuroimaging poses challenging questions for gatekeeping courts. Among the complex evidentiary issues neuroimaging presents for courts and litigants, this Article considers one foundational question: How should courts determine whether neuroimaging evidence is sufficiently reliable for …

Ai Suppression: E-Discovery Software And Brady, Jason Hartline, Liren Shan, Alec Sun, Rebecca Wexler

Faculty Scholarship

Prosecutors regularly rely on AI e-discovery software, known as technology assisted review (TAR) tools, to sort and prioritize digital evidence. These tools implicate constitutional concerns: they can either risk suppressing or help to surface exculpatory and impeachment evidence that prosecutors must disclose under the Brady due process rule. Yet doctrine, agency guidance, and scholarship offer virtually no direction on their use.

This Article examines how TAR affects Brady compliance. Using computer science simulations on synthetic data sets, we show that TAR can either hide or help to expose Brady evidence, depending on how it is configured and the configurations of …

Sex On Trial, Nathalie Greenfield, Sandra L. Babcock

Cornell Law Faculty Publications

On January 21, 2025, the U.S. Supreme Court recognized in Andrew v. White that the State’s introduction of sexualizing evidence in a woman’s capital trial may violate due process. In Brenda Andrew’s case, prosecutors presented evidence about her sexual relationships, clothing, and style of underwear as proof that she was guilty of capital murder. Our research, supported by a grant from the National Science Foundation, reveals for the first time that the prosecution’s tactics in Brenda Andrew’s case were far from unique. Based on a systematic review of the trial transcripts of every woman currently on death row in the …

Maurice Robinson V. The State Of Nevada, 142 Nev. Op. 37 (May 21, 2026), Kaleigh Evanchak

Nevada Supreme Court Summaries

Elder exploitation is charged as one unit per victim, and certain theft offenses may be aggregated when committed as part of a scheme or continuing course of conduct.

Del Toro (Juan) V. State Of Nevada, 142 Nev. Adv. Op. 33 (May 7, 2026), Ashley Arita

Nevada Supreme Court Summaries

Under NRS 176.0931, sex offenders are not required to complete their full registration period before becoming eligible for release from lifetime supervision.

Defining Civil Rico's "Injury To Business Or Property" Requirement: The Supreme Court Takes A Few Steps, Says It Punts, But Actually Fumbles, Randy D. Gordon

Faculty Scholarship

Throughout its history, the RICO statute has presented lawyers with something of an interpretive parlor game. It is indefinite along multiple dimensions and thereby given multiple interpretations, even down to the word level. In Medical Marijuana v. Horn, the Supreme Court set out to define one of RICO's civil-standing provisions: Namely, whether the statute's "injury to business or property" requirement can be satisfied when a plaintiff suffers both economic and personal injuries. In a 5-4 decision, members of the Court engaged in an interpretive battle over the meaning of the phrase and succeeded only in holding that civil RICO does …

Plea Bargain Skepticism When Companies Kill People, Peter R. Reilly

Faculty Scholarship

In 2018 and 2019, two Boeing 737 MAX airplanes fell from the sky, killing 346 people—one of the deadliest corporate crimes in U.S. history. Instead of taking the case to trial, the United States Department of Justice (“DOJ”) addressed the matter by using two different alternative dispute resolution vehicles. First, Boeing was given a three-year deferred prosecution agree-ment. That deal was canceled when DOJ determined the company had breached it. Next, Boeing was given a plea bargain. This Article argues that federal courts, which are empowered to approve or reject plea deals, should be skeptical when the government turns to …

Metrics Not Thresholds: How To Regulate Ai And Other Expert Methods For Use In Criminal Investigations And Proceedings, Rebecca Wexler

Faculty Scholarship

Should regulators set performance thresholds for AI tools used in the criminal legal system? This Article draws on U.S. evidence law for guidance. Its answer is ... don’t. Instead of gatekeeping with ex ante performance thresholds, regulators should require or incentivize metrics of reliability that can be clearly communicated to end-user decisionmakers.

Drug War Repairs Guarantees, Amber Baylor

Faculty Scholarship

Drug legalization, especially cannabis legalization, is a critical step forward in states’ willingness to address systemic disparities, privacy intrusions, violence, and other harms of the drug war. Yet, reforms center on legalization and repair through a narrow lens, focused on changes to the penal code. The public has found that narrow forms of legalization cannot serve their purported reparative purpose. Narrowly drawn legalization is illusory. Drug war harms and punishment for legalized substance use continue. Legalization reforms are vulnerable to political trends, resulting in rollback and retrenchment of drug war operations.

Legalization cannot deliver on its reparative terms without guarantees. …

Revocation Reconsidered: Probation Advocacy Through A Litigation Lens, Shira M. Diner

Faculty Scholarship

Being found in violation of probation has dire consequences. The person found in violation can be imprisoned, upending them from their job, family, and community. Unlike incarceration after a criminal trial, a sentence after a violation of probation is not the result of a legal process characterized by robust due process protections. It is also often not the result of a forceful and thorough defense. It is instead the consequence of a hearing where lawyers with the fixed mindset of an inevitable finding of a violation don’t engage in the same preparation that they would if it was a trial. …

Glossip’S Road Map To Nowhere, Vida Johnson

Georgetown Law Faculty Publications and Other Works

The Supreme Court’s 2025 decision in Glossip v. Oklahoma was heralded as a victory for the defense. This essay argues that the 2025 Glossip decision does little to fix the myriad problems that led to Mr. Glossip’s wrongful conviction. While ultimately the Supreme Court reached the correct outcome this time, the ordinary judicial process and its purported safeguards were not what saved Mr. Glossip’s life. Rather, it was random chance that came to Mr. Glossip’s aid.

Ten years earlier, the Supreme Court, with many of the same Justices on the bench now, paved the way for Mr. Glossip’s execution. The …

The Death Penalty & State Executions In The Mountain West, 1976 - 2024, Mia Tschan, Sydney Mitchell, Yiselle Olivas Ruiz, Dre Boyd-Weatherly, Olivia K. Cheche, Kristian Thymianos, Caitlin J. Saladino, William E. Brown Jr.

Criminal Justice

This fact sheet presents 1976-2024 data on the death penalty and state executions in the five Mountain West states of Arizona, Colorado, New Mexico, Nevada, and Utah. The Death Penalty Information Center (DPIC) report, “State Execution Rates,” includes data on the 36 states that have conducted state executions and the 38 states, federal government, and military institutions that imposed the death penalty between 1976 and 2024. This fact sheet focuses on cumulative executions, executions per capita, and executions per death sentence in each Mountain West state.

Interior Optimal Imprisonment Under Diminishing Marginal Disutility, Tim Friehe, Murat C. Mungan

Faculty Scholarship

This note revisits the important question of how fines and imprisonment should be optimally employed. In D’Antoni et al. (2022), a monotone hazard rate condition implies a corner solution for imprisonment in the observable-wealth benchmark when imprisonment disutility is linear. We show that this result is not robust to offenders facing diminishing marginal disutility of imprisonment. The optimal prison term is interior as long as the marginal disutility associated with large imprisonment terms are low and the harms from the offense are large enough to warrant imprisonment. The sentence length thus becomes a genuine policy margin rather than a boundary …

Uncomfortably Reminiscent: Odonnell V. Harris County In History And Memory, Kellen R. Funk

Faculty Scholarship

In ODonnell v. Harris County, a federal trial court enjoined the misdemeanor bail system of Houston, Texas, freeing approximately 20,000 indigent defendants annually. To do this, the trial court drew upon Reconstruction era precedents establishing intensive federal oversight of state criminal proceedings. The court explicitly invoked the Civil War and Reconstruction transformation of the federal judiciary, comparing the County’s defenses to slavery era arguments. Conversely, when the en banc Fifth Circuit reviewed a similar order in Dallas, Texas, six years later, it rejected this historical framework, condemning such litigation as an impermissible “ongoing federal audit of state criminal proceedings.” …

Body Cameras Use By Federal Agents, Kevin Holst

Center for Cybersecurity

In today’s political climate and increasingly tense view of law enforcement, obtaining a true and accurate account of police–civilian encounters has become more critical than ever. The widespread use of body-worn cameras serves as an essential tool in preventing false, misleading, or selectively edited narratives by providing objective and comprehensive documentation of interactions between law enforcement agents such as ICE and the public. Over the past decade, body cameras have proven beneficial for local police agencies by protecting officers from unfounded accusations, supporting investigations, and increasing overall transparency. As public scrutiny continues to rise, federal agents now face similar challenges, …

(Mis)Judging Suspicion, Sherri Lee Keene

Georgetown Law Faculty Publications and Other Works

Twenty-five years ago, the Supreme Court decided Illinois v. Wardlow, a Fourth Amendment case that allowed the high-crime nature of a location to be considered in determinations of whether there was reasonable suspicion to support a police stop. In making these determinations, courts rarely acknowledge the role that race can play in decisions that factor in the nature of a location as context. Yet even when the race of a defendant is not mentioned, high-crime area designations can act as a proxy for race inviting racial bias into courts’ analyses. Reasonable suspicion analysis involves the interpretation of a suspect’s …

The Psychology Of A Favor: Why Hidden Witness Payments Demand A New Brady Rule, Adam M. Gershowitz

Faculty Publications

Prosecutors and the police regularly pay informants and other witnesses in criminal cases. These payments can be in the form of rewards, relocation expenses, crime victims funds, and even simple cash. Although witness payments are legal, prosecutors are supposed to disclose them under the Brady doctrine because they are favorable evidence that the defense could use to impeach the witness. Yet prosecutors often fail to disclose witness payments because of communication failures with the police, poor training, excessive caseloads, and occasional ethical lapses.

This Article examines dozens of hidden witness payments that prosecutors failed to disclose. In nearly eighty percent …

Structuring The Notional Imprisonment Period When The Accused Is Unfit To Plead – Abdul Ghufran Bin Abdul Wahid V Public Prosecutor, Abhishek Behera, Aaron Yoong

Research Collection Yong Pung How School Of Law

This case comment examines how Abdul Ghufran bin Abdul Wahid v Public Prosecutor [2025] 3 SLR 1572 brings clarity to Singapore’s “fitness to plead” regime by structuring the nominal imprisonment period (“NIP”) as a principled, non-punitive ceiling on confinement for unfit accused persons. It explains the General Division of the High Court’s four-step framework, the elevation of prevention over rehabilitation at the NIP stage, and the constrained role of mental disorders in adjusting the provisional term. It further highlights the decisive influence of psychiatric evidence and explores how the framework mediates between consistency, individualised justice, and public protection.

The Territorial Continuum: American Samoa, Criminal Adjudication, And Territorial Administration, Emmanuel Hiram Arnaud

Faculty Scholarship

The standard account of American territorial expansion posits that territorial acquisition moved along a spectrum of sovereignty. The federal government acquired new inhabited land through conquest or purchase, and the Constitution tasked Congress with organizing and administering the new territories until they were ready to become states. That pattern came to an abrupt halt in 1898 when, at the conclusion of the Spanish-American War, the Supreme Court, fearing the extension of citizenship to, and the permanent integration of, non-White populations into the American polity, suddenly pronounced that the Constitution authorized the holding of colonies. The Court thus sentenced new territories, …

A Prosecutor’S Ethical Duty To Divert, Jordan Stevenson

Legal Writing Competition Winners

In an American courtroom, litigants are divided across an aisle, a gavel grants or divests rights, and a community takes sides. This creates a narrative of duality in the justice system, which many believe is vital to the adversarial legal system. A criminal trial is seen as perpetrator versus victim, but the legal posture is actually government versus individual. In fact, a prosecuting attorney has ethical obligations not just to victims, witnesses, and the broader community, but to defendants as well, in part due to their tremendous discretion to bring or dismiss criminal charges. A prosecutor’s power is far too …

Matadamas-Serrano V. State, 142 Nev. Adv. Op. 20 (Mar. 5, 2026), Mary Shamon

Nevada Supreme Court Summaries

A district court does not commit reversible error by denying a Batson challenge at step one based on strike percentages alone, or by allowing a substitute coroner to give an independent opinion based on autopsy photographs.

Contagious Discrimination: Why Race-Blind Justice In Courtrooms Is Not Enough, Yijia Lu, Murat C. Mungan

Faculty Scholarship

Existing theories of discrimination focus on discrimination at the individual, societal, or organizational level. We highlight the importance of the dynamic relationship between different institutional actors who jointly give rise to discriminatory outcomes. This reveals that discrimination can be contagious: discrimination that would otherwise not occur at one institutional level can arise due to discrimination at another institutional level. Therefore, discrimination by some actors can trickle down and create disparate impacts in processes that would otherwise be free of discrimination. This phenomenon, which we term “contagious discrimination,” can manifest itself in various settings such as employment and commercial trade negotiations. …

Evidence And Assessing Verbatim Transcription Quality Of Black English And Standard American English, L. Alexander Walker Iii

Faculty Scholarship

This chapter explores the accuracy of private transcription services when transcribing Black English and Standard American English. Courts and lawyers in the US regularly rely on transcripts from such services, but third-party verification of their accuracy, especially with respect to their quality when faced with nonstandard language varieties, is lacking. This study draws on experimental methods to contrast the quality of transcription services offered by transcribers and AI route. The quantitative results show that transcription by humans and AI resulted in more mistakes when transcribing Black English than when transcribing Standard American English. Furthermore, a qualitative analysis reveals that these …

Compensation For Victims Of Crimes: Should Victims’ Financial Means And Insurance Coverage Matter? — Criminal Procedure Code 2010, S 359(1); Public Prosecutor V Ong Eng Siew [2025] Sghc 55, Benjamin Joshua Ong

Research Collection Yong Pung How School Of Law

Under s 359(1) of the Criminal Procedure Code 2010, the court can order an offender to compensate the victim with a sum which the victim would have been able to recover in a civil claim in tort against the offender. The courts have used this useful power extensively, though problems remain. One such problem is seen in Ong Eng Siew, where the court declined to make a compensation order. Given the purpose of the compensation system, the court was not correct to hold – in effect – that the purpose of s 359(1) is to benefit only impecunious victims, and …
