Police Frisks, David S. Abrams, Hanming Fang, Priyanka Goonetilleke May 2022

Police Frisks, David S. Abrams, Hanming Fang, Priyanka Goonetilleke

All Faculty Scholarship

The standard economic model of police stops implies that the contraband hit rate should rise when the number of stops falls, ceteris paribus. We provide empirical corroboration of such optimizing models of police behavior by examining changes in stops and frisks around two extraordinary events of 2020 - the pandemic onset and the nationwide protests following the killing of George Floyd. We find that hit rates from pedestrian and vehicle stops generally rose as stops and frisks fell dramatically. Using detailed data, we are able to rule out a number of alternative explanations, including changes in street population, crime, police …


Police Quotas, Shaun Ossei-Owusu Jan 2021

Police Quotas, Shaun Ossei-Owusu

All Faculty Scholarship

The American public is slowly recognizing the criminal justice system’s deep defects. Mounting visual evidence of police brutality and social protests are generating an appetite for something different. How to change this system is still an open question. People across the political spectrum vary in their conceptions of the pressing problems and how to solve them. Interestingly, there is one consequential and overlooked area of the criminal justice system where there is broad consensus: police quotas.

Police quotas are formal and informal measures that require police officers to issue a particular number of citations or make a certain number of …


Prosecuting Civil Asset Forfeiture On Contingency Fees: Looking For Profit In All The Wrong Places, Louis S. Rulli Jan 2021

Prosecuting Civil Asset Forfeiture On Contingency Fees: Looking For Profit In All The Wrong Places, Louis S. Rulli

All Faculty Scholarship

Civil asset forfeiture has strayed far from its intended purpose. Designed to give law enforcement powerful tools to combat maritime offenses and criminal enterprises, forfeiture laws are now used to prey upon innocent motorists and lawful homeowners who are never charged with crimes. Their only sins are that they are carrying legal tender while driving on busy highways or providing shelter in their homes to adult children and grandchildren who allegedly sold small amounts of low-level drugs. Civil forfeiture abuses are commonplace throughout the country with some police even armed with legal waivers for property owners to sign on the …


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, …


Spillover Effects In Police Use Of Force, Justin E. Holz, Roman G. Rivera, Bocar A. Ba Dec 2019

Spillover Effects In Police Use Of Force, Justin E. Holz, Roman G. Rivera, Bocar A. Ba

All Faculty Scholarship

We study the link between officer injuries-on-duty and the force-use of their peers using a network of officers who, through a random lottery, began the police academy together. We find that peer injuries-on-duty increase the probability of using force by 7%. The effect is concentrated in a narrow time window near the event and is not associated with significantly lower injury risk to the officer. Complaints of improper searches and failure to provide service also increase after peer injuries, suggesting that the increase in force might be driven by heightened risk aversion.


Applying Sentinel Event Reviews To Policing, John Hollway, Ben Grunwald Jan 2019

Applying Sentinel Event Reviews To Policing, John Hollway, Ben Grunwald

All Faculty Scholarship

A sentinel event review (SER) is a system-based, multistakeholder review of an organizational error. The goal of an SER is to prevent similar errors from recurring in the future rather than identifying and punishing the responsible parties. In this article, we provide a detailed description of one of the first SERs conducted in an American police department—the review of the Lex Street Massacre investigation and prosecution, which resulted in the wrongful incarceration of four innocent men for 18 months. The results of the review suggest that SERs may help identify new systemic reforms for participating police departments and other criminal …


Mental Disorder And Criminal Justice, Stephen J. Morse Jan 2018

Mental Disorder And Criminal Justice, Stephen J. Morse

All Faculty Scholarship

This paper is a chapter that will appear in REFORMING CRIMINAL JUSTICE: A REPORT OF THE ACADEMY FOR JUSTICE BRIDGING THE GAP BETWEEN SCHOLARSHIP AND REFORM (Erik Luna ed., Academy for Justice 2018). The criminal law treats some people with severe mental disorders doctrinally and practically differently at virtually every stage of the criminal justice process, beginning with potential incompetence to stand trial and ending with the question of competence to be executed, and such people have special needs when they are in the system. This chapter begins by exploring the fundamental mental health information necessary to make informed judgements …


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 …


Strict Liability's Criminogenic Effect, Paul H. Robinson Jan 2017

Strict Liability's Criminogenic Effect, Paul H. Robinson

All Faculty Scholarship

It is easy to understand the apparent appeal of strict liability to policymakers and legal reformers seeking to reduce crime: if the criminal law can do away with its traditional culpability requirement, it can increase the likelihood of conviction and punishment of those who engage in prohibited conduct or bring about prohibited harm or evil. And such an increase in punishment rate can enhance the crime-control effectiveness of a system built upon general deterrence or incapacitation of the dangerous. Similar arguments support the use of criminal liability for regulatory offenses. Greater punishment rates suggest greater compliance.

But this analysis fails …


Root Cause Analysis: A Tool To Promote Officer Safety And Reduce Officer Involved Shootings Over Time, John Hollway, Calvin Lee, Sean Smoot Jan 2017

Root Cause Analysis: A Tool To Promote Officer Safety And Reduce Officer Involved Shootings Over Time, John Hollway, Calvin Lee, Sean Smoot

All Faculty Scholarship

This Article proposes the use of Root Cause Analysis (RCA) as a tool for reducing or preventing officer-involved shootings (OIS). RCA is a method of problem solving designed to identify core underlying factors that contributed to generate an undesirable outcome, organizational accident, or adverse event. Once these core underlying causative factors have been identified, participants in the system can fashion remedies that will prevent future occurrences of similar undesirable outcomes. RCA is part of a prospective, non-blaming “systems approach” to preventing error in complex human systems that has been successfully used to reduce errors in aviation, healthcare, manufacturing, nuclear power, …


Tasers Help Police Avoid Fatal Mistakes, Paul H. Robinson Jan 2016

Tasers Help Police Avoid Fatal Mistakes, Paul H. Robinson

All Faculty Scholarship

This op-ed piece argues that police will inevitably be placed in impossible situations in which they reasonably believe they must shoot to defend themselves but where the shooting in fact turns out to be unnecessary. What can save the police, and the community, from these regular tragedies is a more concerted shift to police use of nonlethal weapons. Taser technology, for example, continues to become increasingly more effective and reliable. While we will always have reasonable mistakes by police in the use of force, it need not be the case that each ends in death or permanent injury. Such a …


Criminal Justice And (A) Catholic Conscience, Leo E. Strine Jr. Jan 2016

Criminal Justice And (A) Catholic Conscience, Leo E. Strine Jr.

All Faculty Scholarship

This article is one person's reflections on how an important influence on his own sense of moral values -- Jesus Christ -- affects his thinking about his own approach to his role as a public official in a secular society, using the vital topic of criminal justice as a focal point. This article draws several important lessons from Christ's teachings about the concept of the other that are relevant to issues of criminal justice. Using Catholicism as a framework, this article addresses, among other things, capital punishment and denying the opportunity for redemption; the problem of racial disparities in the …


Tightening The Ooda Loop: Police Militarization, Race, And Algorithmic Surveillance, Jeffrey L. Vagle Jan 2016

Tightening The Ooda Loop: Police Militarization, Race, And Algorithmic Surveillance, Jeffrey L. Vagle

All Faculty Scholarship

This Article examines the role military automated surveillance and intelligence systems and techniques have supported a self-reinforcing racial bias when used by civilian police departments to enhance predictive policing programs. I will focus on two facets of this problem. First, my research will take an inside-out perspective, studying the role played by advanced military technologies and methods within civilian police departments, and how they have enabled a new focus on deterrence and crime prevention by creating a system of structural surveillance where decision support relies increasingly upon algorithms and automated data analysis tools, and which automates de facto penalization and …
