Fiscal Pressures And Discriminatory Policing: Evidence From Traffic Stops In Missouri, Allison P. Harris, Elliott Ash, Jeffrey A. Fagan

Faculty Scholarship

This paper provides evidence of racial variation in traffic enforcement responses to local government budget stress using data from policing agencies in the state of Missouri from 2001 through 2012. Like previous studies, we find that local budget stress is associated with higher citation rates; we also find an increase in traffic-stop arrest rates. However, we find that these effects are concentrated among White (rather than Black or Latino) drivers. The results are robust to the inclusion of a range of covariates and a variety of model specifications, including a regression discontinuity examining bare budget shortfalls. Considering potential mechanisms, we …

Race And The New Policing, Jeffrey Fagan

Faculty Scholarship

Several observers credit nearly 25 years of declining crime rates to the “New Policing” and its emphasis on advanced statistical metrics, new forms of organizational accountability, and aggressive tactical enforcement of minor crimes. This model has been adopted in large and small cities, and has been institutionalized in everyday police-citizen interactions, especially among residents of poorer, often minority, and higher crime areas. Citizens exposed to these regimes have frequent contact with police through investigative stops, arrests for minor misdemeanors, and non-custody citations or summons for code violations or vehicle infractions. Two case studies show surprising and troubling similarities in the …

Group Threat, Police Officer Diversity And The Deadly Use Of Police Force, Joscha Legewie, Jeffrey Fagan

Faculty Scholarship

Officer-involved killings and racial bias in policing are controversial political issues. Prior research indicates that (perceived) group threat related to political mobilization, economic competition, and the threat of black crime are is an important explanations for variations in police killings across cities in the United States. We argue that a diverse police force that proportionally represents the population it serves mitigates group threat and thereby reduces the number of officer-involved killings. Count models support our argument. They show that group threat is largely driven by the threat of black crime. Black-on-white homicides increase officer-involved killings of African Americans but black-on-black …

Crime And Enforcement In Immigrant Neighborhoods: Evidence From New York City, Garth Davies, Jeffrey Fagan

Faculty Scholarship

Immigration and crime have received much popular and political attention in the past decade, and have been a focus of episodic social attention for much of the history of the U.S. Recent policy and legal discourse suggests that the stigmatic link between immigrants and crime has endured, even in the face of evidence to the contrary. This study addresses the relationship between immigration and crime in urban settings, focusing on areal units where immigrants tend to cluster spatially as well as socially. We ask whether immigration creates risks or benefits for neighborhoods in terms of lower crime rates. The question …

Pot As Pretext: Marijuana, Race, And The New Disorder In New York City Street Policing, Amanda Geller, Jeffrey Fagan

Faculty Scholarship

Although possession of small quantities of marijuana has been decriminalized in New York State since the late 1970s, arrests for marijuana possession in New York City have increased more than tenfold since the mid-1990s, and remain high more than 10 years later. This rise has been a notable component of the city’s “Order Maintenance Policing” strategy, designed to aggressively target low-level offenses, usually through street interdictions known as “stop, question, and frisk” activity. We analyze data on 2.2 million stops and arrests carried out from 2004 to 2008, and identify significant racial disparities in the implementation of marijuana enforcement. These …

Incarceration And The Economic Fortunes Of Urban Neighborhoods, Jeffrey Fagan, Valerie West

Faculty Scholarship

New research has identified the consequences of high rates of incarceration on neighborhood crime rates, but few studies have looked beyond crime to examine the collateral effects of incarceration on the social and economic well being of the neighborhoods themselves and their residents. We assess two specific indicia of neighborhood economic well-being, household income and human capital, dimensions that are robust predictors of elevated crime, enforcement and incarceration rates. We decompose incarceration effects by neighborhood racial composition and socio-economic conditions to account for structural disadvantages in labor force and access to wealth that flow from persistent patterns of residential segregation. …

Street Stops And Broken Windows Revisited: The Demography And Logic Of Proactive Policing In A Safe And Changing City, Jeffrey Fagan, Amanda Geller, Garth Davies, Valerie West

Faculty Scholarship

The contributions of order-maintenance policing and broken windows theory to New York City’s remarkable crime decline have been the subject of contentious debate. The dominant policing tactic in New York since the 1990s has been aggressive interdiction of citizens through street encounters in the search for weapons or drugs. Research showed that minority citizens in the 1990s were disproportionately stopped, frisked and searched at rates significantly higher than would be predicted by their race-specific crime rates, and that this excess enforcement was explained by the social structure of predominantly minority neighborhoods than by either their disorder or their crime rates. …

Henry Louis Gates And Racial Profiling: What's The Problem?, Bernard E. Harcourt

Faculty Scholarship

A string of recent studies has documented significant racial disparities in police stops, searches, and arrests across the country. The issue of racial profiling, however, did not receive national attention until the arrest of Professor Henry Louis Gates, Jr., at his home in Cambridge. This raises three questions: First, did Sergeant Crowley engage in racial profiling when he arrested Professor Gates? Second, why does it take the wrongful arrest of a respected member of an elite community to focus the attention of the country? Third, why is racial profiling so pervasive in American policing?

The answers to these questions are …

An Analysis Of The Nypd's Stop-And-Frisk Policy In The Context Of Claims Of Racial Bias, Andrew Gelman, Alex Kiss, Jeffrey Fagan

Faculty Scholarship

Recent studies by police departments and researchers confirm that police stop racial and ethnic minority citizens more often than whites, relative to their proportions in the population. However, it has been argued stop rates more accurately reflect rates of crimes committed by each ethnic group, or that stop rates reflect elevated rates in specific social areas such as neighborhoods or precincts. Most of the research on stop rates and police-citizen interactions has focused on traffic stops, and analyses of pedestrian stops are rare. In this paper, we analyze data from 175,000 pedestrian stops by the New York Police Department over …

Against Prediction: Sentencing, Policing, And Punishing In An Actuarial Age, Bernard E. Harcourt

Faculty Scholarship

Actuarial methods – i.e., the use of statistical rather than clinical methods on large datasets of criminal offending rates to determine different levels of offending associated with one or more group traits, in order to (1) predict past, present or future criminal behavior and (2) administer a criminal justice outcome – now permeates the criminal law and its enforcement. With the single exception of racial profiling against African-Americans and Hispanics, most people view the turn to the actuarial as efficient, rational, and wealth-maximizing. The fact is, law enforcement agencies can detect more crime with the same resources if they investigate …
