Most use-of-force policies utilized by U.S. police agencies make fundamental ordinal assumptions about officers’ force responses to subject resistance. These policies consist of varying levels of force and resistance along an ordinally ranked continuum of severity. We empirically tested the ordinal assumptions that are ubiquitous to police use-of-force continua within the United States using 1 year’s use-of-force data from a municipal police department. Applying a quantitative technique known as categorical regression with optimal scaling, we found the assumptions of ordinality within the studied department’s use-of-force continuum (which is similar to many police use-of-force continua within the United States) are not met. Specifying physical force as a “lower” force option than less-lethal tools is associated with increased officer injury and decreased subject injury. Our findings call into question use-of-force continua featuring ordinal rankings for varying categories of less-lethal force.

Wood et al. (2020) studied the rollout of a procedural justice training program in the Chicago Police Department and found large and statistically significant impacts on complaints and sustained complaints against police officers and police use of force. This document describes a subtle statistical problem that led the magnitude of those estimates to be inflated. We then re-analyze the data using a methodology that corrects for this problem. The re-analysis provides less strong conclusions about the effectiveness of the training than the original study: although the point estimates for most outcomes and specifications are negative and of a meaningful magnitude, the confidence intervals typically include zero or very small effects. On the whole, we interpret the data as providing suggestive evidence that procedural justice training reduced the use of force, but no statistically significant evidence for a reduction in complaints or sustained complaints.

Purpose The purpose of this paper is to examine whether the representativeness of police departments, i.e. the extent to which the demographics of sworn police officers mirror their local constituency’s demographic makeup, has an effect on communities. The study seeks to explain whether community complaints about police use of force are related to the representativeness of the police department. Design/methodology/approach The study examines the relationships between use of force complaints lodged against a police department and the representativeness of the police vis-à-vis their community using ordinary least squares regression and city fixed-effects models. The stratified sample of 100 large US cities uses data from the US Census Equal Employment Opportunity Survey and the Bureau of Justice Statistics Law Enforcement Management and Administration Statistics Survey from several points-in-time. Findings The analysis suggests that racial makeup and, to a lesser extent, local residency of police departments might matter in reducing community conflict with police, as represented by use of force complaints. However, the fixed-effects model suggests that unobserved community-level characteristics and context matter more than police departments’ representativeness. Originality/value This study seeks to provide a unique perspective and empirical evidence on community conflict with police by integrating the public administration theory of representative bureaucracy with criminal justice theories of policing legitimacy. The findings have implications for urban policing as well as law enforcement human capital and public management practices, which is essential to understand current crises in police-citizen relations in the US, especially in minority communities.

Police organisations across the world are embracing body-worn video camera technology. The justification for this is to enhance public trust in police, provide transparency in policing activity, increase police accountability, reduce conflict between police and public, and to provide a police perspective of incidents and events. However, while the corpus of research into the efficacy and operational practicalities of police use of body-worn video cameras is developing, questions on some elements of their impact remain. The majority of scholarship has hitherto been evaluations focused on the impact of the cameras on police use of force and on the numbers of complaints against the police. Alternatively, this article explores body-worn video cameras from the perspective of police detainees, and specifically, detainees’ perceptions of the capacities of body-worn video cameras to deliver promised increased levels of accountability in policing. The article draws on a survey and research interviews with 907 police detainees across four Australian jurisdictions. While respondents largely support the use of body-worn video cameras they also identify a number of caveats. We conclude by suggesting that there are still impediments in body-worn video cameras to achieving the level of accountability promised by advocates and expected by the respondents.

ObjectivesTo estimate the effects of race and ethnicity on suspect injuries during use of force encounters with police in Tucson, Arizona.MethodsData on all use of force cases recorded by the Tucson Police Department from January 2018 to March 2020 were analysed. Logistic regression was used to estimate the effects of race and ethnicity on the likelihood of suspect injuries controlling for a variety of other factors.ResultsOverall, 28.5% of people who had force used against them by Tucson police were injured. Multivariate analyses reveal that among those who had force used against them, African-American suspects were significantly less likely than white suspects to be injured. The risk of injury for other racial and ethnic groups is about the same as the risk for white suspects. Resisting arrest and seeking to escape from police custody do not increase the risk of injury among suspects, but assaulting officers or other individuals does increase the risk of injury. Certain types of force, such as canines, firearms and TASERs, are associated with significantly elevated risks of injury among suspects.ConclusionsNumerous interest groups have raised concerns about the police use of force against minorities. Using publicly available data, this analysis examined the effects of race and ethnicity on risk of injury during the use of force encounters with police in Tucson. The findings reveal that minorities are not injured at elevated rates relative to whites. To the contrary, African-American suspects are less likely to be injured than white suspects are.

Purpose The purpose of this paper is to examine whether community-oriented policing (COP) influences rates of police use of force across communities, and whether the impact of COP varies according to the level of violent crime in communities. Design/methodology/approach A range of data sources including police use of force reports, online surveys of Officers-in-Charge and recorded crime data was used to examine the association between formal and informal community consultation and the frequency of police use of force, across 64 socially challenged communities in Australia. Findings Poisson multilevel modelling indicated no overall association between informal or formal community engagement and rates of police use of force. However, significant interaction terms for both informal and formal community consultation with violent crime rates indicated that higher levels of informal and formal community consultation were associated with lower rates of police use of force in communities with higher levels of violent crime. This relationship was not evident in low violent crime areas. Research limitations/implications Communities were purposively sampled to have a high propensity for police use of force, on the basis that they had high rates of violent crime, or high levels of socio-economic disadvantage, or both. This research should be replicated with a representative sample of communities. Practical implications The findings extend the potential benefits of COP to reducing the use of coercive policing tactics in high violent crime communities. Originality/value This study finds that COP can reduce the frequency of violent encounters between police and community members in high violent crime communities.

Purpose Body-worn cameras (BWCs) have been adopted in police agencies across the USA in efforts to increase police transparency and accountability. This widespread implementation has occurred despite some notable resistance to BWCs from police officers in some jurisdictions. This resistance poses a threat to the appropriate implementation of this technology and adherence to BWC policies. The purpose of this paper is to examine factors that could explain variation in officer receptivity to BWCs. Design/methodology/approach The authors assess differences between officers who volunteered to wear a BWC and officers who resisted wearing a BWC as part of a larger randomized controlled trial of BWCs in the Phoenix Police Department. The authors specifically examine whether officer educational attainment, prior use of a BWC, attitudes toward BWCs, perceptions of organizational justice, support for procedural justice, noble cause beliefs, and official measures of officer activity predict receptivity to BWCs among 125 officers using binary logistic regression. Findings The findings indicate limited differences between BWC volunteers and resistors. Volunteers did have higher levels of educational attainment and were more likely to agree that BWCs improve citizen behaviors, relative to their resistant counterparts. Interestingly, there were no differences in perceptions of organizational justice, self-initiated activities, use of force, or citizen complaints between these groups. Originality/value Though a growing body of research has examined the impact of BWCs on officer use of force and citizen complaints, less research has examined officer attitudes toward the adoption of this technology. Extant research in this area largely focusses on general perceptions of BWCs, as opposed to officer characteristics that could predict receptivity to BWCs. This paper addresses this limitation in the research.
