The authors review research on police effectiveness in reducing crime, disorder, and fear in the context of a typology of innovation in police practices. That typology emphasizes two dimensions: one concerning the diversity of approaches, and the other, the level of focus. The authors find that little evidence supports the standard model of policing—low on both of these dimensions. In contrast, research evidence does support continued investment in police innovations that call for greater focus and tailoring of police efforts, combined with an expansion of the tool box of policing beyond simple law enforcement. The strongest evidence of police effectiveness in reducing crime and disorder is found in the case of geographically focused police practices, such as hot-spots policing. Community policing practices are found to reduce fear of crime, but the authors do not find consistent evidence that community policing (when it is implemented without models of problem-oriented policing) affects either crime or d...

What Can Police Do to Reduce Crime, Disorder, and Fear?

Research Summary
This study examined 40 African-American young men's direct and vicarious experiences with police harassment and violence, and their impact on perceptions of police. Study findings highlight the value of using comprehensive and nuanced measures of police/citizen encounters and underscore the importance of examining the impact of accumulated adverse experiences.

Policy Implications
The findings have implications for police oversight policies. In particular, police organizations should work toward developing complaint review processes that are not merely accessible to citizens but also inspire confidence among them. These efforts are crucial toward improving the image of police in minority communities and positively impacting citizen trust of, and satisfaction with, the police.

“police don't like black people”: african‐american young men's accumulated police experiences*

Police officers were compared with community members in terms of the speed and accuracy with which they made simulated decisions to shoot (or not shoot) Black and White targets. Both samples exhibited robust racial bias in response speed. Officers outperformed community members on a number of measures, including overall speed and accuracy. Moreover, although community respondents set the decision criterion lower for Black targets than for White targets (indicating bias), police officers did not. The authors suggest that training may not affect the speed with which stereotype-incongruent targets are processed but that it does affect the ultimate decision (particularly the placement of the decision criterion). Findings from a study in which a college sample received training support this conclusion.

Across the thin blue line: police officers and racial bias in the decision to shoot.

Explanations of police coercion have been traditionally embedded within sociological, psychological, and organizational theoretical frameworks. Largely absent from the research are examinations exploring the role of neighborhood context on police use-of-force practices. Using data collected as part of a systematic social observation study of police in Indianapolis, Indiana, and St. Petersburg, Florida, this research examines the influence of neighborhood context on the level of force police exercise during police-suspect encounters using hierarchical linear modeling techniques. The authors found police officers are significantly more likely to use higher levels of force when suspects are encountered in disadvantaged neighborhoods and those with higher homicide rates, net of situational factors (e.g., suspect resistance) and officer-based determinants (e.g., age, education, and training). Also found is that the effect of the suspect's race is mediated by neighborhood context. The results reaffirm Smith's 1...

Neighborhood Context and Police Use of Force

Using data collected as part of an observational study of the police in Indianapolis, Indiana, and St. Petersburg, Florida, this article examines police use of force to gain a better understanding of why the police resort to force. Like analyses from previous observational studies, the present inquiry borrows from both sociological and psychological theoretical orientations to explore various determinants of force. Unlike previous examinations, the universe of behaviors considered is substantially expanded to include numerous types or levels of force, ranging from verbal commands and threats to the use of impact methods. An ordered probit analysis of 3,116 police-suspect encounters shows that officers often respond to legal stimuli (e.g., suspects' resistance, safety concerns) when applying force. Countering previous findings, it found that officers were not more coercive toward disrespectful suspects. However, the analysis revealed that officers were also influenced by extra-legal factors. Male, nonwhite...

Situational and officer-based determinants of police coercion

Researchers have long noted the link between police culture and coercion. To date, however, there have been no empirical studies of this relationship. Using data collected as part of a systematic social observation study of the police in Indianapolis, Indiana, and St. Petersburg, Florida, this research examines the relationship between traditional views of police culture—from an attitudinal perspective-and coercion—from a behavioral perspective. After developing a classification scheme of officers' outlooks in the context of police culture, we examine the extent to which officers' alignment with cultural attitudes translates into differences in coercive behavior. The findings indicate that those officers who closely embody the values of the police culture are more coercive compared with those that differentially align with the culture, suggesting that police use of force is a function of officers' varying attitudinal commitments to the traditional view of police culture. The implications of these findings for policy and future research are considered.

Police culture and coercion

Police researchers have devoted a considerable amount of empirical attention to testing the impact college education has on police performance. The counterargument to the education debate is that experience, in learning the police craft, is what contributes to differences in performance. The current study adds to both lines of research by examining the impact of education and experience on one of the core features of the police role: the use of coercion. The findings indicate that varying levels of education and experience are related to differences in the use of coercion in encounters with citizens. Encounters involving officers with any college education result in significantly less verbal force compared to those with a high school education. However, only those encounters involving officers with a 4-year degree result in significantly less physical force. Finally, encounters involving officers with greater experience result in less verbal and physical force.

Police Education, Experience, and the Use of Force

Drawing on Tedeschi and Felson’s (1994) theory of coercive actions for conceptual guidance as well as principles underlying the notion of a force continuum structure (i.e., proportionality and incrementalism), this research examines 3,544 police–suspect encounters from an observational study of the police in an attempt to better understand the transactional process of the police–suspect encounter. Results indicate, within the context of a force continuum structure, that officers escalated the level of force in about one of five encounters involving nonresistant suspects, and de‐escalated the level of force in three of four encounters involving resistant suspects. A series of logistic and multinomial regression models show that a number of factors differentially affect the manner in which officers apply force. The results suggest that before one can begin to judge the appropriateness of police force, one should measure and consider the extent to which force is applied proportionately and incrementally.
