The Trouble With Time Served, Kimberly Ferzan Jul 2023

The Trouble With Time Served, Kimberly Ferzan

All Faculty Scholarship

Every jurisdiction in the United States gives criminal defendants “credit” against their sentence for the time they spend detained pretrial. In a world of mass incarceration and overcriminalization that disproportionately impacts people of color, this practice appears to be a welcome mechanism for mercy and justice. In fact, however, crediting detainees for time served is perverse. It harms the innocent. A defendant who is found not guilty, or whose case is dismissed, gets nothing. Crediting time served also allows the state to avoid internalizing the full costs of pretrial detention, thereby making overinclusive detention standards less expensive. Finally, crediting time …


Remodelling Criminal Insanity: Exploring Philosophical, Legal, And Medical Premises Of The Medical Model Used In Norwegian Law, Linda Gröning, Unn K. Haukvik, Stephen J. Morse, Susanna Radovic Jan 2022

Remodelling Criminal Insanity: Exploring Philosophical, Legal, And Medical Premises Of The Medical Model Used In Norwegian Law, Linda Gröning, Unn K. Haukvik, Stephen J. Morse, Susanna Radovic

All Faculty Scholarship

This paper clarifies the conceptual space of discussion of legal insanity by considering the virtues of the ‘medical model’ model that has been used in Norway for almost a century. The medical model identifies insanity exclusively with mental disorder, and especially with psychosis, without any requirement that the disorder causally influenced the commission of the crime. We explore the medical model from a transdisciplinary perspective and show how it can be utilised to systematise and reconsider the central philosophical, legal and medical premises involved in the insanity debate. A key concern is how recent transdiagnostic and dimensional approaches to psychosis …


Internal And External Challenges To Culpability, Stephen J. Morse Jan 2022

Internal And External Challenges To Culpability, Stephen J. Morse

All Faculty Scholarship

This article was presented at “Guilty Minds: A Virtual Conference on Mens Rea and Criminal Justice Reform” at Arizona State University’s Sandra Day O’Connor College of Law. It is forthcoming in Arizona State Law Journal Volume 53, Issue 2.

The thesis of this article is simple: As long as we maintain the current folk psychological conception of ourselves as intentional and potentially rational creatures, as people and not simply as machines, mental states will inevitably remain central to ascriptions of culpability and responsibility more generally. It is also desirable. Nonetheless, we are in a condition of unprecedented internal challenges to …

Misdemeanors By The Numbers, Sandra G. Mayson, Megan T. Stevenson Jan 2020

Misdemeanors By The Numbers, Sandra G. Mayson, Megan T. Stevenson

All Faculty Scholarship

Recent scholarship has underlined the importance of criminal misdemeanor law enforcement, including the impact of public-order policing on communities of color, the collateral consequences of misdemeanor arrest or conviction, and the use of misdemeanor prosecution to raise municipal revenue. But despite the fact that misdemeanors represent more than three-quarters of all criminal cases filed annually in the United States, our knowledge of misdemeanor case processing is based mostly on anecdote and extremely localized research. This Article represents the most substantial empirical analysis of misdemeanor case processing to date. Using multiple court-record datasets, covering several million cases across eight diverse jurisdictions, …


Foreword: Abolition Constitutionalism, Dorothy E. Roberts Jan 2019

Foreword: Abolition Constitutionalism, Dorothy E. Roberts

All Faculty Scholarship

In this Foreword, I make the case for an abolition constitutionalism that attends to the theorizing of prison abolitionists. In Part I, I provide a summary of prison abolition theory and highlight its foundational tenets that engage with the institution of slavery and its eradication. I discuss how abolition theorists view the current prison industrial complex as originating in, though distinct from, racialized chattel slavery and the racial capitalist regime that relied on and sustained it, and their movement as completing the “unfinished liberation” sought by slavery abolitionists in the past. Part II considers whether the U.S. Constitution is an …


Neurohype And The Law: A Cautionary Tale, Stephen J. Morse Jan 2019

Neurohype And The Law: A Cautionary Tale, Stephen J. Morse

All Faculty Scholarship

This chapter suggests that for conceptual, empirical, and practical reasons, neuroscience in general and non-invasive brain imaging in particular are not likely to revolutionize the law and our conception of ourselves, but may make modest contributions to legal policy and case adjudication if the legal relevance of the science is properly understood.


A General Mitigation For Disturbance-Driven Crimes?: Psychic State, Personal Choice, And Normative Inquiries, Paul H. Robinson Oct 2018

A General Mitigation For Disturbance-Driven Crimes?: Psychic State, Personal Choice, And Normative Inquiries, Paul H. Robinson

All Faculty Scholarship

It is argued here that the narrow provoked “heat of passion” mitigation available under current law ought to be significantly expanded to include not just murder but all felonies and not just “heat of passion” but potentially all mental or emotional disturbances, whenever the offender’s situation and capacities meaningfully reduce the offender’s blameworthiness for the violation. In determining eligibility for mitigation, the jury should take into account (a) the extent to which the offender was acting under the influence of mental or emotional disturbance (the psychic state inquiry), (b) given the offender’s situation and capacities, the extent to which one …


Statutory Rape, Paul H. Robinson, Tyler Scot Williams Jan 2018

Statutory Rape, Paul H. Robinson, Tyler Scot Williams

All Faculty Scholarship

It is common for criminal law scholars from outside the United States to discuss the “American rule” and compare it to the rule of other countries. As this volume makes clear, however, there is no such thing as an “American rule.” Because each of the states, plus the District of Columbia and the federal system, have their own criminal law, there are fifty-two American criminal codes.

American criminal law scholars know this, of course, but they too commonly speak of the “general rule” as if it reflects some consensus or near consensus position among the states. But the truth is …


A Brief Summary And Critique Of Criminal Liability Rules For Intoxicated Conduct, Paul H. Robinson Jan 2018

A Brief Summary And Critique Of Criminal Liability Rules For Intoxicated Conduct, Paul H. Robinson

All Faculty Scholarship

This essay provides an overview of the legal issues relating to intoxication, including the effect of voluntary intoxication in imputing to an offender a required offense culpable state of mind that he may not actually have had at the time of the offense; the effect of involuntary intoxication in providing a defense by negating a required offense culpability element or by satisfying the conditions of a general excuse; the legal effect of alcoholism or addiction in rendering intoxication involuntary; and the limitation on using alcoholism or addiction in this way if the offender can be judged to be reasonably responsible …


Bias In, Bias Out, Sandra G. Mayson Jan 2018

Bias In, Bias Out, Sandra G. Mayson

All Faculty Scholarship

Police, prosecutors, judges, and other criminal justice actors increasingly use algorithmic risk assessment to estimate the likelihood that a person will commit future crime. As many scholars have noted, these algorithms tend to have disparate racial impacts. In response, critics advocate three strategies of resistance: (1) the exclusion of input factors that correlate closely with race; (2) adjustments to algorithmic design to equalize predictions across racial lines; and (3) rejection of algorithmic methods altogether.

This Article’s central claim is that these strategies are at best superficial and at worst counterproductive because the source of racial inequality in risk assessment lies …


Crimes That Changed Our World: Tragedy, Outrage, And Reform: Chapter One: 1911 Triangle Factory Fire: Building Safety Codes, Paul H. Robinson, Sarah M. Robinson Jan 2018

Crimes That Changed Our World: Tragedy, Outrage, And Reform: Chapter One: 1911 Triangle Factory Fire: Building Safety Codes, Paul H. Robinson, Sarah M. Robinson

All Faculty Scholarship

This first chapter of the recently published book Crimes That Changed Our World: Tragedy, Outrage, and Reform, examines the process by which the tragic 1911 Triangle Factory Fire provoked enormous outrage that in turn created a local then national movement for workplace and building safety that ultimately became the foundation for today’s building safety codes. What is particularly interesting, however, is that the Triangle Fire was not the worst such tragedy in its day. Why should it be the one that ultimately triggers social progress?

The book has 21 chapters, each of which traces the tragedy-outrage-reform dynamic in a …


Distributive Principles Of Criminal Law, Paul H. Robinson, Tyler Scot Williams Jan 2018

Distributive Principles Of Criminal Law, Paul H. Robinson, Tyler Scot Williams

All Faculty Scholarship

This first chapter from the recently published book Mapping American Criminal Law: Variations across the 50 States documents the alternative distributive principles for criminal liability and punishment — desert, deterrence, incapacitation of the dangerous — that are officially recognized by law in each of the American states. The chapter contains two maps visually coded to display important differences: the first map shows which states have adopted desert, deterrence, or incapacitation as a distributive principle, while the second map shows which form of desert is adopted in those jurisdictions that recognize desert. Like all 38 chapters in the book, which covers …


The Subversions And Perversions Of Shadow Vigilantism, Paul H. Robinson, Sarah M. Robinson Jan 2018

The Subversions And Perversions Of Shadow Vigilantism, Paul H. Robinson, Sarah M. Robinson

All Faculty Scholarship

This excerpt from the recently published Shadow Vigilantes book argues that, while vigilantism, even moral vigilantism, can be dangerous to a society, the real danger is not of hordes of citizens, frustrated by the system’s doctrines of disillusionment, rising up to take the law into their own hands. Frustration can spark a vigilante impulse, but such classic aggressive vigilantism is not the typical response. More common is the expression of disillusionment in less brazen ways by a more surreptitious undermining and distortion of the operation of the criminal justice system.

Shadow vigilantes, as they might be called, can affect the …


Sexual Consent And Disability, Jasmine E. Harris Jan 2018

Sexual Consent And Disability, Jasmine E. Harris

All Faculty Scholarship

Our nation is engaged in deep debate over sexual consent. But to date the discussion has overlooked sexual consent’s implications for a key demographic: people with mental disabilities, for whom the reported incidence of sexual violence is three times that of the nondisabled population. Even as popular debate overlooks the question of sexual consent for those with disabilities, contemporary legal scholars critique governmental overregulation of this area, arguing that it diminishes the agency and dignity of people with disabilities. Yet in defending their position, these scholars rely on empirical data from over twenty years ago, when disability and sexual assault …

Brief Of Amici Curiae Of 11 Addiction Experts In Support Of Appellee, Gene M. Heyman, Scott O. Lilienfeld, Stephen J. Morse, Sally L. Satel Sep 2017

Brief Of Amici Curiae Of 11 Addiction Experts In Support Of Appellee, Gene M. Heyman, Scott O. Lilienfeld, Stephen J. Morse, Sally L. Satel

All Faculty Scholarship

This brief is a critique of the brain disease model and many supposed implications of that model. It begins with a brief history of the model and moves to a discussion of the motivations behind the characterization of addiction as a “chronic and relapsing brain disease.” We follow with an enumeration of fallacious inferences based upon the brain disease model, including the very notion that addiction becomes a “brain disease” simply because it has neurobiological correlates. Regardless of whether addiction is labeled a brain disease, the real question, we contend, is whether the behavioral manifestations of addiction are unresponsive to …


Tragedy, Outrage & Reform: Crimes That Changed Our World: 1983 – Thurman Beating - Domestic Violence, Paul H. Robinson, Sarah M. Robinson Aug 2017

Tragedy, Outrage & Reform: Crimes That Changed Our World: 1983 – Thurman Beating - Domestic Violence, Paul H. Robinson, Sarah M. Robinson

All Faculty Scholarship

Can a crime make our world better? Crimes are the worst of humanity’s wrongs but, oddly, they sometimes do more than anything else to improve our lives. As it turns out, it is often the outrageousness itself that does the work. Ordinary crimes are accepted as the background noise of our everyday existence but some crimes make people stop and take notice – because they are so outrageous, or so curious, or so heart-wrenching. These “trigger crimes” are the cases that this book is about.

They offer some incredible stories about how people, good and bad, change the world around …

Can a crime make our world better? Crimes are the worst of humanity’s wrongs but, oddly, they sometimes do more than anything else to improve our lives. It is often the outrageousness itself that does the work. Ordinary crimes are accepted as the background noise of everyday existence but some crimes make people stop and take notice – because they are so outrageous or so heart-wrenching.

This brief essay explores the dynamic of tragedy, outrage, and reform, illustrating how certain kinds of crimes can trigger real social progress. Several dozen such “trigger crimes” are identified but four in particular are …


Democratizing Criminal Law: Feasibility, Utility, And The Challenge Of Social Change, Paul H. Robinson Jan 2017

Democratizing Criminal Law: Feasibility, Utility, And The Challenge Of Social Change, Paul H. Robinson

All Faculty Scholarship

The notion of “democratizing criminal law” has an initial appeal because, after all, we believe in the importance of democracy and because criminal law is so important – it protects us from the most egregious wrongs and is the vehicle by which we allow the most serious governmental intrusions in the lives of individuals. Given criminal law’s special status, isn’t it appropriate that this most important and most intrusive governmental power be subject to the constraints of democratic determination?

But perhaps the initial appeal of this grand principle must give way to practical realities. As much as we are devoted …


Rationing Criminal Justice, Richard A. Bierschbach, Stephanos Bibas Jan 2017

Rationing Criminal Justice, Richard A. Bierschbach, Stephanos Bibas

All Faculty Scholarship

Of the many diagnoses of American criminal justice’s ills, few focus on externalities. Yet American criminal justice systematically overpunishes in large part because few mechanisms exist to force consideration of the full social costs of criminal justice interventions. Actors often lack good information or incentives to minimize the harms they impose. Part of the problem is structural: criminal justice is fragmented vertically among governments, horizontally among agencies, and individually among self-interested actors. Part is a matter of focus: doctrinally and pragmatically, actors overwhelmingly view each case as an isolated, short-term transaction to the exclusion of broader, long-term, and aggregate effects. …

How Being Right Can Risk Wrongs, Paul H. Robinson, Sarah M. Robinson Aug 2016

How Being Right Can Risk Wrongs, Paul H. Robinson, Sarah M. Robinson

All Faculty Scholarship

This is a chapter from the new book The Vigilante Echo. Previous chapters have made clear that some vigilantism can be morally justified where the government has failed in its promise under the social contract to protect and to do justice. But this chapter explains how even moral vigilante action can be problematic for the larger society. Vigilantes may try to do the right thing but are likely to lack the training and professional neutrality of police. They may be successful, but only on pushing the crime problem to an adjacent neighborhood. Because their open lawbreaking may seem admirable …

Actions Speak Louder Than Images: The Use Of Neuroscientific Evidence In Criminal Cases, Stephen J. Morse Jun 2016

Actions Speak Louder Than Images: The Use Of Neuroscientific Evidence In Criminal Cases, Stephen J. Morse

All Faculty Scholarship

This invited commentary for Journal of Law & the Biosciences considers four empirical studies previously published in the journal of the reception of neuroscientific evidence in criminal cases in the United States, Canada, England and Wales, and the Netherlands. There are conceded methodological problems with all, but the data are nonetheless instructive and suggestive. The thesis of the comment is that the courts are committing the same errors that have bedeviled the reception of psychiatric and psychological evidence. There is insufficient caution about the state of the science, and more importantly, there is insufficient understanding of the relevance of the …


Identifying Criminals’ Risk Preferences, Murat C. Mungan, Jonathan Klick Jan 2016

Identifying Criminals’ Risk Preferences, Murat C. Mungan, Jonathan Klick

All Faculty Scholarship

There is a 250 year old presumption in the criminology and law enforcement literature that people are deterred more by increases in the certainty rather than increases in the severity of legal sanctions. We call this presumption the Certainty Aversion Presumption (CAP). Simple criminal decision making models suggest that criminals must be risk-seeking if they behave consistently with CAP. This implication leads to disturbing interpretations, such as criminals being categorically different than law abiding people, who often display risk-averse behavior while making financial decisions. Moreover, policy discussions that incorrectly rely on criminals’ risk attitudes implied by CAP are ill-informed, and …


What's Wrong With Sentencing Equality?, Richard A. Bierschbach, Stephanos Bibas Jan 2016

What's Wrong With Sentencing Equality?, Richard A. Bierschbach, Stephanos Bibas

All Faculty Scholarship

Equality in criminal sentencing often translates into equalizing outcomes and stamping out variations, whether race-based, geographic, or random. This approach conflates the concept of equality with one contestable conception focused on outputs and numbers, not inputs and processes. Racial equality is crucial, but a concern with eliminating racism has hypertrophied well beyond race. Equalizing outcomes seems appealing as a neutral way to dodge contentious substantive policy debates about the purposes of punishment. But it actually privileges deterrence and incapacitation over rehabilitation, subjective elements of retribution, and procedural justice, and it provides little normative guidance for punishment. It also has unintended …


Justice: 1850s San Francisco And The California Gold Rush, Paul H. Robinson, Sarah M. Robinson Jan 2015

Justice: 1850s San Francisco And The California Gold Rush, Paul H. Robinson, Sarah M. Robinson

All Faculty Scholarship

Using stories from the 1848-1851 California gold miners, the 1851 San Francisco vigilante committees, Nazi concentration camps of the 1940s, and wagon trains of American westward migration in the 1840s, the chapter illustrates that it is part of human nature to see doing justice as a value in itself—in people’s minds it is not dependent for justification on the practical benefits it brings. Having justice done is sufficiently important to people that they willingly suffer enormous costs to obtain it, even when they were neither hurt by the wrong nor in a position to benefit from punishing the wrongdoer.

The Rise And Fall And Resurrection Of American Criminal Codes, Paul H. Robinson Jan 2015

The Rise And Fall And Resurrection Of American Criminal Codes, Paul H. Robinson

All Faculty Scholarship

This brief essay summarizes the virtues of the modern American codification movement of the 1960s and 70s, putting it in a larger global context, then describes how these once-enviable codes have been systematically degraded with thoughtless amendments, a process of degradation that is accelerating each year. After exploring the political dynamics that promote such degradation, the essay suggests the principles and procedures for fixing the current codes and, more importantly, structural changes to the process that could avoid the restart of degradation in the future.


The Moral Vigilante And Her Cousins In The Shadows, Paul H. Robinson Jan 2015

The Moral Vigilante And Her Cousins In The Shadows, Paul H. Robinson

All Faculty Scholarship

By definition, vigilantes cannot be legally justified – if they satisfied a justification defense, for example, they would not be law-breakers – but they may well be morally justified, if their aim is to provide the order and justice that the criminal justice system has failed to provide in a breach of the social contract. Yet, even moral vigilantism is detrimental to society and ought to be avoided, ideally not by prosecuting moral vigilantism but by avoiding the creation of situations that would call for it. Unfortunately, the U.S. criminal justice system has adopted a wide range of criminal law …
