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 …

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 …

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 …

Evidence-Informed Criminal Justice, Brandon L. Garrett

Faculty Scholarship

The American criminal justice system is at a turning point. For decades, as the rate of incarceration exploded, observers of the American criminal justice system criticized the enormous discretion wielded by key actors, particularly police and prosecutors, and the lack of empirical evidence that has informed that discretion. Since the 1967 President’s Commission on Law Enforcement and Administration of Justice report, The Challenge of Crime in a Free Society, there has been broad awareness that the criminal system lacks empirically informed approaches. That report unsuccessfully called for a national research strategy, with an independent national criminal justice research institute, along …

Project Safe Neighborhoods In Chicago: Looking Back A Decade Later, Ben Grunwald, Andrew V. Papachristos

Faculty Scholarship

Project Safe Neighborhoods (PSN) is a federally funded initiative that brings together federal, state, and local law enforcement to reduce gun violence in urban centers. In Chicago, PSN implemented supply-side gun policing tactics, enhanced federal prosecution of gun crimes, and notification forums warning offenders of PSN’s heightened criminal sanctions. Prior evaluations provide evidence that PSN initiatives have reduced crime in the first few years of their operation. But over a decade after the program was established, we still know little about whether these effects are sustained over an extended period of time. This Article examines PSN Chicago, an anti-violence program …

The American Death Penalty Decline, Brandon L. Garrett, Alexander Jakubow, Ankur Desai

Faculty Scholarship

American death sentences have both declined and become concentrated in a small group of counties. In his dissenting opinion in Glossip v. Gross in 2014, Justice Stephen Breyer highlighted how from 2004 to 2006, "just 29 counties (fewer than 1% of counties in the country) accounted for approximately half of all death sentences imposed nationwide." That decline has become more dramatic. In 2015, fifty-one defendants were sentenced to death in thirty-eight counties. In 2016, thirty-one defendants were sentenced to death in twenty-eight counties. In the mid-1990s, by way of contrast, over 300 people were sentenced to death in as many …

Neuroscience And Behavioral Genetics In Us Criminal Law: An Empirical Analysis, Nita A. Farahany

Faculty Scholarship

The goal of this study was to examine the growing use of neurological and behavioral genetic evidence by criminal defendants in US criminal law. Judicial opinions issued between 2005–12 that discussed the use of neuroscience or behavioral genetics by criminal defendants were identified, coded and analysed. Yet, criminal defendants are increasingly introducing such evidence to challenge defendants’ competency, the effectiveness of defense counsel at trial, and to mitigate punishment.

Dna And Distrust, Kerry Abrams, Brandon L. Garrett

Faculty Scholarship

Over the past three decades, government regulation and funding of DNA testing has reshaped the use of genetic evidence across various fields, including criminal law, family law, and employment law. Courts have struggled with questions of when and whether to treat genetic evidence as implicating individual rights, policy trade-offs, or federalism problems. We identify two modes of genetic testing: identification testing, used to establish a person’s identity, and predictive testing, which seeks to predict outcomes for a person. Judges and lawmakers have often drawn a bright line at predictive testing, while allowing uninhibited identity testing. The U.S. Supreme Court in …

Decriminalizing Delinquency: The Effect Of Raising The Age Of Majority On Juvenile Recidivism, Charles E. Loeffler, Ben Grunwald

Faculty Scholarship

In the last decade, a number of states have expanded the jurisdiction of their juvenile courts by increasing the maximum age to 18. Proponents argue that these expansions reduce crime by increasing access to the beneficial features of the juvenile justice system. Critics counter that the expansions risk increasing crime by reducing deterrence. In 2010, Illinois raised the maximum age for juvenile court for offenders who commit a misdemeanor. By examining the effect of this law on juvenile offenders in Chicago, this paper provides the first empirical estimates of the consequences of recent legislative activity to raise the age of …

Culpability And Modern Crime, Samuel W. Buell

Faculty Scholarship

Criminal law has developed to prohibit new forms of intrusion on the autonomy and mental processes of others. Examples include modern understandings of fraud, extortion, and bribery, which pivot on the concepts of deception, coercion, and improper influence. Sometimes core offenses develop to include similar concepts, such as when reforms in the law of sexual assault make consent almost exclusively material. Many of these projects are laudable. But progressive programs in substantive criminal law can raise difficult problems of culpability. Modern iterations of criminal offenses often draw lines using concepts involving relative mental states among persons whose conduct is embedded …

“White Collar” Crimes, Samuel W. Buell

Faculty Scholarship

In addition to serving as a précis of the subject of ‘white collar’ crime, this chapter does three things. First, it deals with white collar crime’s longstanding definitional problem, rejecting several standard approaches and arguing that the category is most usefully understood according to the conceptual legal problem these offenses generate. White collar crimes, much more than other offenses, are committed in social settings in which undesirable behaviors are embedded within socially welcome conduct. Thus they are difficult to set apart and extract through clearly specified ex ante rules of law. Second, the chapter illustrates this definitional claim, and discusses …

Prosecutorial Discretion In Three Systems: Balancing Conflicting Goals And Providing Mechanisms For Control, Sara Sun Beale

Faculty Scholarship

In regulating the authority and discretion exercised by contemporary prosecutors,national systems balance a variety of goals, many of which are in tension or direct conflict. Forexample, making prosecutors politically or democratically accountable may conflict with theprinciple of prosecutorial neutrality, and the goal of efficiency may conflict with accuracy. National systems generally seek to foster equal treatment of defendants and respect for theirrights while also controlling or reducing crime and protecting the rights of victims. Systems thatrecognize prosecutorial discretion also seek to establish and implement policy decisions aboutthe best ways to address various social problems, priorities, and the allocation of resources. …

The Deterrent Effect Of Death Penalty Eligibility: Evidence From The Adoption Of Child Murder Eligibility Factors, Michael D. Frakes, Matthew Harding

Faculty Scholarship

We draw on within-state variations in the reach of capital punishment statutes between 1977 and 2004 to identify the deterrent effects associated with capital eligibility. Focusing on the most prevalent eligibility expansion, we estimate that the adoption of a child murder factor is associated with an approximately 20% reduction in the homicide rate of youth victims. Eligibility expansions may enhance deterrence by (1) paving the way for more executions and (2) providing prosecutors with greater leverage to secure enhanced non-capital sentences. While executions themselves are rare, this latter channel is likely to be triggered fairly regularly, providing a reasonable basis …

Bad Nature, Bad Nurture, And Testimony Regarding Maoa And Slc6a4 Genotyping In Murder Trials, Nita A. Farahany, William Bernet, Cindy L. Vnencak-Jones, Stephen A. Montgomery

Faculty Scholarship

Recent research—in which subjects were studied longitudinally from childhood until adulthood—has started to clarify how a child’s environment and genetic makeup interact to create a violent adolescent or adult. For example, male subjects who were born with a particular allele of the monoamine oxidase A gene and also were maltreated as children had a much greater likelihood of manifesting violent antisocial behavior as adolescents and adults. Also, individuals who were born with particular alleles of the serotonin transporter gene and also experienced multiple stressful life events were more likely to manifest serious depression and suicidality. This research raises the question …

Behavioural Genetics In Criminal Cases: Past, Present And Future, Nita A. Farahany, William Bernet

Faculty Scholarship

Researchers studying human behavioral genetics have made significant scientific progress in enhancing our understanding of the relative contributions of genetics and the environment in observed variations in human behavior. Quickly outpacing the advances in the science are its applications in the criminal justice system. Already, human behavioral genetics research has been introduced in the U.S. criminal justice system, and its use will only become more prevalent. This essay discusses the recent historical use of behavioral genetics in criminal cases, recent advances in two gene variants of particular interest in the criminal law, MAOA and SLC6A4, the recent expert testimony on …

Trial By Jury Involving Persons Accused Of Terrorism Or Supporting Terrorism, Neil Vidmar

Faculty Scholarship

This chapter explores issues in jury trials involving persons accused of committing acts of international terrorism or financially or otherwise supporting those who do or may commit such acts. The jury is a unique institution that draws upon laypersons to decide whether a person charged with a crime is guilty or innocent. Although the jury is instructed and guided by a trial judge and procedural rules shape what the jury is allowed to hear, ultimately the laypersons deliberate alone and render their verdict. A basic principle of the jury system is that at the start of trial the jurors should …
