Analyzing Fatal Police Shootings: The Roles of Social Vulnerability, Race, and Place in the U.S.

IntroductionSocial vulnerability, race, and place are three important predictors of fatal police shootings. This research offers the first assessment of these factors at the zip code level. MethodsThe 2015-2022 Mapping Police Violence and Washington Post Fatal Force Data (2015-2022) were used and combined with the American Community Survey (2015-2022). The social vulnerability index (SVI) was computed for each zip code by using indicators suggested by CDC, then categorized into low-, medium-, and high-SVI. The analytical file included police officers who fatally shot 6,901 individuals within 32,736 zip codes between 2015-2022. Negative Binomial Regression (NBRG) models were run to estimate the association between number of police shootings and zip code SVI, racial composition, and access to guns using 2015-2022 data. ResultsMoving from low-SVI to high-SVI revealed the number of fatal police shootings increased 8.3 times, with the highest increases in Blacks (20.4 times), and Hispanics (27.1 times). The NBRG showed that moderate-, and high-SVI zip codes experienced higher fatal police shootings by 1.97, and 3.26 times than low-SVI zip codes; zip code racial composition, working age population, number of violent crimes, number of police officers and access to a gun, were other predictors of fatal police shootings. ConclusionsSocial vulnerability and racial composition of a zip code are associated with fatal police shooting, both independently and when considered together. What drives deadly police shootings in the United States is not one single factor, but rather complex interactions between social-vulnerability, race, and place that must be tackled synchronously. Action must be taken to address underlying determinants of disparities in policing.

Are the geographic disparities in U.S. violent crime rising?

Inequality in economic and social outcomes across U.S. regions has grown in recent decades. The economic theory of crime predicts that this increased variability would raise geographic disparities in violent crime. Instead, I find that geographic disparities in homicide rates decreased. Moreover, these same decades saw decreases in the geographic disparities in policing, incarceration, and the share of the population that is African American. Thus, changes in policing, incarcerations, and racial composition could have led to a decrease in inequality in homicide rates. Moreover, the joint provision of law enforcement by local, state, and federal authorities may have reduced the impact of economic distress on violent crime.

DOJ Intervention and the Checkpoint Shift: Profiling Hispanic Motorists under the 287 (g) Program

This research examines whether the Department of Justice's (DOJ's) investigation into the Alamance County Sheriff's Office, a 287(g) program participant, influenced the policing behavior of other 287(g)-participating agencies in North Carolina. The study reveals that these agencies increased stops of Hispanic drivers at checkpoints following the DOJ lawsuit, indicating a strategic shift in response to potential DOJ scrutiny. Our findings suggest a phenomenon where 287(g) agencies, under threat of investigation, modify their discriminatory strategies, perpetuating racial and ethnic disparities in policing. This adds to the understanding of 287(g) and its role in fostering racial profiling.

“When the Cruiser Lights Come On”: Using the Science of Bias & Culture to Combat Racial Disparities in Policing

Abstract In this essay, we highlight the interplay between individuals' psychological processes and sociocultural systems in producing and maintaining racial bias. We use a conceptual tool we call the culture cycle to map these dynamics, and illustrate them with research and in-depth examples from our work reducing racial disparities in routine policing in Oakland, California. We feature the most common police encounter – the vehicle stop – and highlight evidence-based interventions we developed both to reduce the frequency of vehicle stops and mitigate racial disparities in stops. Throughout, we draw on our expertise in the social psychology of bias, culture, and inequality, as well as our experiences building research-driven partnerships with public- and private-sector leaders, to inform organizational and societal change.

Disrupting the Effects of Implicit Bias: The Case of Discretion & Policing

Abstract Police departments tend to address operational challenges with training approaches, and implicit bias in policing is no exception. However, psychological scientists have found that implicit biases are very difficult to reduce in any lasting, meaningful way. Because they are difficult to change, and nearly impossible for the decision-maker to recognize, training to raise awareness or teach corrective strategies is unlikely to succeed. Recent empirical assessments of implicit bias trainings have shown, at best, no effect on racial disparities in officers' actions in the field. In the absence of effective training, a promising near-term approach for reducing racial disparities in policing is to reduce the frequency of actions most vulnerable to the influence of bias. Specifically, actions that allow relatively high discretion are most likely to be subject to bias-driven errors. Several cases across different policing domains reveal that when discretion is constrained in stop-and-search decisions, the impact of racial bias on searches markedly declines.

‘The bar is different as a woman’: A thematic analysis of career advice given by female police officers

Abstract In an effort to reduce gender disparities in policing and move beyond the current legitimacy crisis faced by the profession, there has been a renewed focus on increasing the recruitment and retention of female police officers. Beyond understanding why current female officers have remained in the field, it is important to understand why some have left the profession altogether. The current study employs deductive and inductive coding of a mixed-methods self-report survey from 154 current and former female officers in the Dallas Police Department (DPD). We sought to examine the advice that current and former female police officers would give to other women who might want to enter or promote within policing. Responses highlighted challenges related to the impact on family life, navigating the male-dominated culture, maintaining one’s sense of identity and integrity, and creating strong social support networks. Implications for the DPD and other agencies are discussed.

Institutional interactions and racial inequality in policing: How everyday encounters bridge individuals, organizations, and institutions

AbstractRacial disparities in policing are profound and accompanied by equally persistent gaps in trust. Analyses of these and other racial inequities are often bifurcated between institutional and individual levels of analysis. Here, I describe how everyday contacts between the public and doctors, teachers, or police officers—institutional interactions—can bridge these levels. Organizations direct and coordinate these agents' individual discretion; at the same time, individual agents relate to the public in ways institutions themselves cannot. The dual nature of these encounters links individual and dyadic processes to organizational and institutional ones. Using police stops as a paradigmatic example, I illustrate how institutional interactions contribute to racial gaps in police‐community trust, how they can be used as a platform for changing the relationship between law enforcement and the public, and how they can inform research on racial inequality in a range of institutional contexts, including health and education.

The geography of (un)reasonable suspicion: Rethinking causes of racial disparities in police stops

AbstractIn Illinois vs. Wardlow (2000), the U.S. Supreme Court ruled that presence in a “high‐crime” area is one factor that police can consider when establishing reasonable suspicion to justify a Terry stop. Some legal scholars argue that through this decision the Court propagated inequity in police stops by setting a lower evidentiary standard for establishing reasonable suspicion in neighborhoods with greater numbers Black residents, which are more likely than White neighborhoods to be considered crime hot spots. To assess these claims, I analyze pedestrian stop data from the Chicago Police Department for the years 2016 and 2017. Using spatial regression techniques, I evaluate relationships between neighborhood measures of Black disadvantage, police stop justifications, and “hit rates” of stops. The results suggest that reasonable suspicion is uniquely constructed in disadvantaged Black neighborhoods but that this does not result in significantly different enforcement rates. Based on these results, I argue that policing scholars must reconsider sources of inequity in policing and, in particular, consider the role of the law in shaping these outcomes.

A Behavioural Theory of Discrimination in Policing

Abstract A large economic literature studies whether racial disparities in policing are explained by animus or by beliefs about group crime rates. But what if these beliefs are incorrect? We analyse a model where officers form beliefs using crime statistics, but do not properly account for the fact that they will detect more crime in more heavily policed communities. This creates a feedback loop where officers over-police groups that they (incorrectly) believe exhibit high crime rates. This inferential mistake can exacerbate discrimination even among officers with no animus and who sincerely believe that disparities are driven by real differences in crime rates.

“Most Officers are More or Less Colorblind”: Police Officers' Reflections on the Role of Race and Ethnicity in Policing

Several studies worldwide have demonstrated that ethnic minorities are more likely to be stopped, questioned and searched by the police. In this paper, we explore how police officers themselves discuss and make sense of ethnic disparities in police stops. Based on interviews with 25 police officers in two police precincts in Denmark the paper illustrates how officers actively reflect on the (un)importance of ethnicity for policing. Findings point to how the officers both rejected that ethnicity directly mattered for who they chose to stop, as well as how they offered alternative and indirect explanations for why ethnic minorities were stopped more often.

Racial-Ethnic Disparities in Police and Prosecutorial Drug Charging: Analyzing Organizational Overlap in Charging Patterns at Arrest, Filing, and Conviction

Objective: Explore racial-ethnic disparities in drug charging trajectories from arrest to conviction. Methods: We analyze racial-ethnic disparities in charging severity across arrest, filing, and conviction for felony drug offense cases in Miami-Dade County between 2010-2015 (N=25,559) using a “distance traveled” approach by estimating the severity of charges based on the probability of incarceration at conviction. We use these estimates to predict the severity of charges at arrest and filing, and examine differences in the severity of charges between stages. Results: Compared to White non-Latinx people, police charge Black Latinx people with drug crimes that are 1.8 times more severe and Black non-Latinx people with drug crimes that are 1.6 times more severe at arrest. These inequalities are maintained throughout the charging trajectory. Greater charge reductions occur between arrest and filing than between filing and conviction, highlighting the importance of police in charging trajectories. We find small increases in charging trajectory, where racial-ethnic disparities persist at conviction. Conclusions: Examining charging at arrest is critical to understanding racial-ethnic disparities in charging trajectories, where unequal arrest charges become institutionalized throughout the charging process. Organizational dynamics between police and prosecutors may lead to drug charging practices that systematically disadvantage Black people in Miami-Dade County.

Racial Bias in Police Traffic Stops: White Residents’ County-Level Prejudice and Stereotypes Are Related to Disproportionate Stopping of Black Drivers

Racial disparities in policing are well documented, but the reasons for such disparities are often debated. In the current research, we weighed in on this debate using a regional-level bias framework: We investigated the link between racial disparities in police traffic stops and regional-level racial bias, employing data from more than 130 million police traffic stops in 1,413 U.S. counties and county-level measures of racial bias from more than 2 million online respondents. Compared with their population share in county demographics, Black drivers were stopped at disproportionate rates in the majority of counties. Crucially, disproportionate stopping of Black drivers was higher in counties with higher levels of racial prejudice by White residents (rs = .07−.36). Furthermore, county-level aggregates of White people’s threat-related stereotypes were less consistent in predicting disproportionate stopping (rs = .00−.19). These observed relationships between regional-level bias and racial disparities in policing highlight the importance of the context in which police operate.

"Suck It Up, Buttercup": Understanding and Overcoming Gender Disparities in Policing.

Women police officers report elevated symptoms of mental disorders when compared to men police officers. Researchers have indicated that the occupational experience of policing differs greatly among men and women. Indeed, police culture is characterized by hegemonic masculinity, which appears to negatively impact both men and women. The current study examined the contrast between the experiences of men and women police officers. Police officers (n = 17; 9 women) in Saskatchewan participated in semi-structured interviews. Thematic network analysis identified themes related to the experience of policing for both men and women police officers. There were six organizing themes identified in relation to the global theme of Gendered Experiences: (1) Discrimination; (2) Sexual Harassment; (3) Motherhood and Parental Leave; (4) Identity; (5) Stereotypically Feminine Attributes; and (6) Hegemonic Masculinity. Pervasive gender norms appear detrimental for both men and women police officers, as well as the communities they serve. The current results, coupled with the emerging disposition for progress expressed by police services, offer opportunities to develop tailored and focused interventions and policies to support police officers.

Driving While Black and Brown in Vermont: Can Race Data Analysis Contribute to Reform?

Many states now require law enforcement to collect race data on traffic stops, but there has been little research on the use of that data to inform public policy or reform efforts at the agency level. This article addresses that lacuna by presenting results from the first statewide analysis of Vermont traffic stop data. Racial threat theory, a subset of stratification theory, would predict that policing in a predominantly white state like Vermont would exhibit lower racial disparities than states with a more racially diverse population because the “threat” to white dominance is less. The results contradict that prediction. Vermont, despite its reputation as a liberal state, is not different from other states in exhibiting wide racial disparities in policing. And yet, analysis and dissemination of race data in policing, by providing an evidentiary basis for citizen claims of racial bias, contributed to action on the part of the state legislature and government to address racial discrimination not only in policing but also in the broader criminal justice system. We report on those reform efforts and on the actions taken by three reform-minded law enforcement agencies to reduce and eliminate unjustifiable racial disparities in policing.

Racial Disparities In Stop and Frisk Distributions by the Philadelphia Police Department

The rates of police stops of Black and White pedestrians vary greatly in Philadelphia, Pennsylvania. Using a propensity score design, this study matches the rates of stops using stop data characteristics from the Philadelphia Police Department to further analyze racial disparities in police stops. Re-weighting allows to better analyze stop distributions by assessing the difference of frisk rates between Blacks and Whites. The purpose of comparing the stops in similar situations is that if the location of the stop is controlled for, along with the gender, year, and time of day of the stop occurrence, the explainatory variable left to be a plausible reason in stop rate differences between the groups is race. Black pedestrians in Philadelphia are disproportionally frisked more than White pedestrians, 15% vs. 10%. However, Philadelphia police are more likely to recover contraband from frisked Black pedestrians.

Fines, Fees, Forfeitures, and Disparities: A Link Between Municipal Reliance on Fines and Racial Disparities in Policing

We investigate a possible linkage between municipal reliance on fines, fees, and forfeitures as a revenue source and policing behavior. With a dataset of four million traffic stops made by North Carolina municipalities, we demonstrate that a regular reliance on fines, fees, and forfeitures has powerful, predictable, and racially distinct impacts on black and white drivers, and that fiscal stress exacerbates these differences. A greater regular reliance on fines, fees, and forfeitures is linked to a decrease in the probability of white, but not black, drivers being searched; and increased odds of finding contraband among those white drivers who are searched, but no such change for black drivers. We validate the North Carolina tests with aggregate analyses of municipalities across four states.

Representative bureaucracy and impartial policing

AbstractRepresentative bureaucracy theory expects minority bureaucrats to advance the interests of minority citizens. Yet, little attention has been given to the variation in the acceptability, incentives and risks of representation across bureaucratic domains. Analysis of over two million police vehicle stops from four different US departments reveals that African American police officers do not treat African Americans preferentially, yet they mitigate existing racial disparities in policing. Compared with White officers, African Americans seem less disposed to use their discretion. They are disinclined to search drivers, yet inclined to cite them, displaying comparatively low disparities across social groups. These findings extend to pure traffic violations, and are robust to entropy balancing reweighting. We provisionally attribute African American police officers' impartial policing style to their compelling need to display their performance, and avoid blame, amidst intra‐organizational pressures and risks ensuing from the political salience of the police's clash with minority communities.

A large-scale analysis of racial disparities in police stops across the United States.

We assessed racial disparities in policing in the United States by compiling and analysing a dataset detailing nearly 100 million traffic stops conducted across the country. We found that black drivers were less likely to be stopped after sunset, when a 'veil of darkness' masks one's race, suggesting bias in stop decisions. Furthermore, by examining the rate at which stopped drivers were searched and the likelihood that searches turned up contraband, we found evidence that the bar for searching black and Hispanic drivers was lower than that for searching white drivers. Finally, we found that legalization of recreational marijuana reduced the number of searches of white, black and Hispanic drivers-but the bar for searching black and Hispanic drivers was still lower than that for white drivers post-legalization. Our results indicate that police stops and search decisions suffer from persistent racial bias and point to the value of policy interventions to mitigate these disparities.
