A process evaluation of the Effective Mental and Behavioral Health Emergency Diversion (EMBHED) project
Hundreds of innovative co- and alternative-responder approaches have been created and offered around the United States to assist law enforcement to better respond to individuals experiencing a mental or behavioral health crisis, substance abuse, homelessness, and other related and co-occurring issues. Yet, the vast majority of these programs have not been subjected to evaluative research. The current study provides a process evaluation of the Eff…
Racial/Ethnic Diversity in Positions of Power in U.S. Law Enforcement
Increasing minority representation in law enforcement has long been viewed as a means of improving police-citizen relations. Yet, little scholarly attention has examined whether racial/ethnic diversity translates into desired outcomes. These studies largely measure the racial/ethnic composition of the agency in general—not in positions of power where they are most likely to make an impact on department policy/practice (i.e., ‘active representatio…
The Benefits and Supervisory Styles of Women Police Leaders
While research has identified four main police supervisory styles, it is unclear whether the framework accurately represents the supervisory styles of women. We explored the benefits of promoting women in policing and examined their supervisory styles, drawing on interviews with 38 ranking women. Participants attributed three benefits to promoting women – diversity, people-orientation, and conscientiousness. All 34 who described their supervisory…
Considering violence against police by citizen race/ethnicity to contextualize representation in officer-involved shootings
Present but not prevalent
Federal funding streams, the International Association of Chiefs of Police, and policing executives and scholars alike have advocated for more researcher-practitioner partnerships in American law enforcement. While a few studies have explored the growth and prevalence of research partnerships in policing, less attention has been placed on the organizational correlates of such collaborative relationships. Using a nationally representative sample o…
The Prevalence of Female Representation in Supervisory and Management Positions in American Law Enforcement
Increasing gender diversity in American policing has long been a focus of reform efforts since the 1960s. Although the proportion of women in the profession improved initially and research has focused on the gender breakdown of police organizations in general, less scholarly and empirical attention has been directed to female representation in positions of power (i.e., supervisory and management roles). Using data from the 2013 Law Enforcement Ma…
Police worldviews, unconscious bias, and their potential to contribute to racial and ethnic disparities in New York Police Department (Nypd) stops for reason of “furtive movement”
In Floyd et al. v The City of New York (2013), the federal district court judge ruled that the New York Police Department (NYPD) was engaging in unconstitutional stop-and-frisk practices that targeted predominately Black and Latino New Yorkers. Among the major decisions made in Floyd (2013), the judge identified “Furtive Movement” as being a weak indicator for establishing the reasonable suspicion needed to justify a Terry stop. Moreover, the jud…
Examining a Ferguson Effect on College Students’ Motivation to Become Police Officers
The current study examines the impact of the Ferguson Effect and related public scrutiny on college students’ motivation to become police officers. Using data from 654 students located at two US universities with over 20,000 students, the results indicate that students’ who perceived that officer motivation and dangerousness has been affected by negative media scrutiny had significantly higher log-odds of strongly agreeing that such scrutiny has …
Assessing dangerousness in policing
Research Summary A robust body of research findings has established that policing is a dangerous profession. Few scholars, however, have investigated the full picture of the hazards in policing, which includes deaths occurring in both felonious and nonfelonious circumstances. In this study, we examine nearly 50 years of all police officer line‐of‐duty deaths (1970–2016) using data from the Officer Down Memorial Page. We focus on long‐term trends …
The War on Cops
Heather Mac Donald’s The War on Cops: How the New Attack on Law and Order Makes Everyone Less Safe is sure to be controversial for many criminologists. Building on her previous work, Mac Donald del
De-policing and crime in the wake of Ferguson
Was there a Ferguson Effect on crime rates in large U.S. cities
Defensible Space Theory
Defensible space theory was proposed by an architect named Oscar Newman in 1972. The theory suggests that the physical design of a living environment can be used to reduce crime. Newman posited that three key elements − territoriality, surveillance, and image/milieu − act both individually and in concert to assist in the creation of a safe environment. The theoretical framework, modifications and evolution of the theory, criticisms, and practical…
