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

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 …

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

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 …

Privacy, Poverty, And Big Data: A Matrix Of Vulnerabilities For Poor Americans, Mary Madden, Michele E. Gilman, Karen Levy, Alice Marwick

All Faculty Scholarship

This Article examines the matrix of vulnerabilities that low-income people face as a result of the collection and aggregation of big data and the application of predictive analytics. On one hand, big data systems could reverse growing economic inequality by expanding access to opportunities for low-income people. On the other hand, big data could widen economic gaps by making it possible to prey on low-income people or to exclude them from opportunities due to biases entrenched in algorithmic decision-making tools. New kinds of “networked privacy” harms, in which users are simultaneously held liable for their own behavior and the actions …

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. …
