Type of contact and evaluations of police officers: The effects of procedural justice across three types of police–citizen contacts

The public's perception of the police is important because it is linked to several important outcomes, including compliance and cooperation with police. Long recognized as being important, research has investigated the factors associated with citizens' evaluations of the police. The way police do their jobs, in addition to what they accomplish, has recently emerged as being a significant determinant of citizens' evaluations of police. What remains largely unexamined is whether this relationship varies across distinct types of contacts between the police and citizens. The current study estimated the effects of citizens' perceptions of procedural justice on overall ratings of officer performance across three types of police–citizen encounters. Results showed that procedurally fair treatment is the most important predictor of citizens' evaluations.     

Aggressive Policing and the Deterrence of Crime

Recent analyses of the relationship between crime and an aggressive patrol strategy have led to no single conclusion concerning the deterrent power of aggressive policing. This research adds to that debate by exploring the effects of a variety of aggressive patrol tactics on several different crimes. The empirical analysis, based on cross-sectional data from sixty urban neighborhoods, indicates that there appears to be no stable complex of police actions that constitute an aggressive patrol strategy. However, one form of police action usually included under the rubric of aggressive patrol—suspicion stops—may indeed deter certain types of criminal activity.     

Managing Police Patrol Time: The Role of Supervisor Directives

Contemporary police practice advocates the importance of proactive policing activities. Proactive policing reforms emphasize self‐initiated tasks during unassigned patrol time and directed activities based on supervisor review of crime analysis and problem identification. Our study analyzes data from systematic social observations of police patrol officers to examine how officers spent their discretionary time. We find that, on average, over three quarters of a patrol officers’ shift is unassigned. During this time, officers primarily self‐initiate routine patrol, or back up other officers on calls to which they were not dispatched. Just 6 percent of unassigned time activities are directed by supervising officers, dispatchers, other officers or citizens. Moreover, directives provided by supervisors are vague, general in form, and do not operationalize problem‐oriented policing, community‐oriented policing, or proactive policing strategies. We conclude that first, a very significant proportion of patrol officer time is spent uncommitted that could be better utilized doing proactive, problem‐oriented policing activities, and second, supervisors need to provide patrol officers with much more detailed directives, based on sound crime analysis, to help capitalize on the under‐utilization of patrol officer time.     

Does police patrol in large areas prevent crime? Revisiting the Kansas City Preventive Patrol Experiment

Research Summary

The Kansas City Preventive Patrol Experiment (KCPPE) was seen by its developers to have produced “consistent evidence of the lack of effects of any consequence on crime,” a conclusion that was to have a strong impact on assumptions about police patrol for almost half a century. We identified the original official crime data from the KCPPE, and reanalyzed outcomes focusing on a comparison of the “proactive” versus “control” beats (“reactive beats” were criticized because of violations of treatment integrity); examining broad categories of crime (to increase statistical power); and using count regression models. Our findings are not unequivocal, but point to modest impacts of police patrol on crime in police beats.

Policy Implications

Our findings suggest that lessons drawn for half a century from the KCPPE need to be revisited. The KCPPE does not show that police patrol in large areas has no influence on crime, and this finding is consistent with several more recent studies. At the same time, we note that the effects of patrol in the KCPPE using our analysis strategy, and those found in other studies of preventive patrol in larger areas, are about half that found in hot spots policing studies. This suggests that police agencies ideally should invest in focused hot spots policing initiatives. However, absent an ability to manage such initiatives, or the crime analysis capabilities to identify crime hot spots routinely, simpler preventive patrol schemes to utilize uncommitted patrol time can be seen as potentially effective in preventing crime.     

A multimethod approach to community evaluation of police performance

The aim of the present study is to examine the ability of police peers and supervisors to predict police street performance, as measured by citizen evaluations of the service received on recent police service calls. One question to be answered was whether there was any correlation between what a police supervisor, a police peer patrol officer, and a citizen percieved as “good” police performance. It was hypothesized that peer patrol officers would more accurately predict the quality of police street performance than would police supervisors. Results supported the hypothesis. An additional finding of the present study related to the feasibility of the evaluation of police street performance by citizen consumers.     

INVESTIGATING THE NORMATIVE ASPECTS OF PUBLIC POLICY

This article challenges the idea that political philosophy must be of peripheral concern in the study of public policy through an exploration of the concept of harm and the debate over aggressive police patrol. This exploration begins with a brief discussion of the ways the concept of harm figures in the justification and administration of police work. It proceeds through an exposition of differing ways the concept of harm can be defined, the normative overtones of these varying definitions, and some of their policy ramifications with regard to police work. Finally, the way conceptual variation figures in policy debate is explored in the context of the debate over aggressive police patrol—the policy of maximizing the surveillance and criminal interception aspects of police activity as a patrol strategy.     

The Police Officer Perception Project (POPP): An experimental evaluation of factors that impact perceptions of the police

Objectives

To experimentally evaluate the effects of attire and patrol strategy esthetics on participants’ perceptions of police officers.

Methods

Using a rigorously controlled experimental methodology, I present participants (N = 307) with images of police officers in different attire (i.e., uniform and civilian) and patrol strategies (i.e., on a bicycle, on foot, and in a vehicle) and measure their perceptions of these officers as aggressive, approachable, friendly, respectful, and accountable.

Results

Participants express relatively positive perceptions of the police; however, their perceptions vary as a function of sociodemographics, attire, and patrol strategy. Police officers are generally perceived more favorably when presented in police uniform than when presented in civilian clothing. Police officers are also generally perceived more favorably when presented on a bicycle and/or on foot than when presented in a vehicle.

Conclusions

Merely observing police officers in different attire and patrol capacities produces substantial variation in perceptions of those officers. Given that most ‘police interaction’ occurs in relatively unceremonious settings without any exchange of formal dialogue between the public and the police (e.g., observing a police officer in passing), these findings are particularly fruitful for informing both research and practice. This is the first known study to use an experimental methodology to examine how esthetic factors of different patrol strategies can impact perceptions of the police.

     

Analyzing the nature of police involvements: A research note concerning the effects of forms of police mobilization

Studies of the police have reported that much of the work patrol persons do is service-oriented. However, many of those researches relied upon citizen-initiated involvements as units of analysis. Here the distinction has been made between reactive and proactive forms of police mobilization. When activity data are analyzed in this fashion, it is found that the police initiate a larger proportion of law enforcement activities than was supposed. The implications for research are discussed.     

Officer proactivity: A comparison between police field training officers and non-field training officers

This article examines the behavioral differences between police field training officers (FTOs) and non-FTOs in problem-focused efforts and aggressive preventive patrol. The former refers to officer-initiated security checks and attempts to locate citizens, while the latter includes officer-initiated field interrogations and traffic stops. Data used were collected from Indianapolis, Indiana and St. Petersburg, Florida during the summers of 1996 and 1997. Findings show that FTOs, especially those in St. Petersburg, are more proactive than non-FTOs in attempting to locate suspects and witnesses, but they do not differ in the level of proactivity with respect to security checks, field interrogations, and traffic stops. Implications for future research and policy are discussed.     

A comparison of Chinese and the U.S. police cadets’ occupational attitudes

While police attitudes and behaviors have been the subject of a large number of studies conducted since the 1960s, very few studies had assessed Chinese police officers’ work-related attitudes and compared them with those of the U.S. police cadets. Using survey data collected from 263 Chinese and American police cadets, the research empirically tested whether Chinese and American police cadet attitudes differed across four attitudinal dimensions: aggressive patrol, order maintenance, legal restrictions, and distrust of citizens. Bivariate and multivariate results showed that Chinese cadets displayed occupational outlooks that distinguished them from their American counterparts. Chinese cadets supported aggressive patrol and were more distrustful of citizens than their American counterparts. American cadets were more favorable of order maintenance activities and more accepting of legal restrictions compared with Chinese cadets. Implications for future research and policy are discussed.     

A PROACTIVE RESPONSE TO FAMILY VIOLENCE: THE RESULTS OF A RANDOMIZED EXPERIMENT

Recent British work has focused attention on preventing repeat victimization as part of an overall crime prevention strategy. Because domestic violence victims are among those most likely to suffer multiple victimizations, they are logical candidates for programs targeted at reducing repeat victimization.
This article reports on a joint law enforcement-social services approach to reduce the incidence of repeat domestic violence. The research design randomly assigned households reporting domestic incidents within two public housing police service areas in New York to receive or not receive a follow-up to the initial patrol response. (The follow-up visit was conducted by a police officer and a social worker.) In addition, housing projects in the same area were randomly assigned to receive or not receive public education about domestic violence.
Neither treatment produced a reduction in violence. However, households in projects that had received public education and households that received the follow-up visits were both more likely to report new violence to the police than households that did not receive the treatments. Moreover, the effect of the follow-up visit was most pronounced among households with more serious histories of violence. The results suggest that the interventions increased citizens' confidence in the ability of the police to handle domestic situations.     

The Responsibility of the Police Command for Street-Level Actions

This article examines federal judicial doctrine concerning the responsibility of police officials for patrol misconduct. The current standard requiring a showing by plaintiffs of an "affirmative link" between street-level action and the intention of commanders is challenged in two ways. First, through the application of organizational analysis to the premises of leading cases in the doctrine, and, second, by considering three suits alleging patterns of patrol misconduct, in which the elements of a new standard of command responsibility can be discerned. The authors argue that a standard based on a strengthened doctrine of respondeat superior will help insure the preservation of due process rights in citizen encounters with the police. The article recommends the imposition of departmental record keeping requirements for personnel evaluations and for allegations and investigations of patrol misconduct. A further recommendation would require departmental regulations on the use of force.     

The influence of job assignment on community engagement: bicycle patrol and community-oriented policing

The purpose of this study is to compare a specialized community-oriented policing (COP) unit to a reactive unit on officer perceptions of public contact and officer perceptions of job performance. We also compare bicycle patrol officers to motor vehicle patrol officers within these units. Using a static group comparison design, questionnaires were distributed to officers within the Toronto Police Service (n = 178). Bicycle patrol is associated with more contacts with the public and higher rates of proactive policing when compared to motor vehicle patrol and bicycle officers are more likely to rate higher on several measures of crime control. Officers with a COP mandate engage with the public for a wider variety of reasons compared to those with a reactive mandate, and are more likely to rate higher on perceptions of performing job duties in a procedurally just manner. This study demonstrates the value of a specialized COP unit that includes bicycle patrol in achieving tenets of COP. It contributes to the literature on COP and the use of bicycle patrol in law enforcement by presenting the perspective of the police officer.     

Optimal patrol routes: interdicting and pursuing rhino poachers

Interdiction patrolling (also known as hot spots policing) is a proactive police operation that depends on good planning. And the pursuit of fleeing suspects is a challenging operation that all police forces engage in on a regular basis. We give software tools that improve the effectiveness of both. We demonstrate the effectiveness of our tools by applying them to the case of rhino poaching in wildlife reserves. An interdiction patrol pre-emptively seeks out poaching parties within a reserve. Upon picking up the trail of a poaching party, a pursuit team needs a pursuit strategy that optimizes their chances of an interception. Our interdiction patrol route tool identifies optimal interdiction patrol routes to walk. This tool is based on a Stackelberg game and represents different types of poachers and their utilities. These utilities are updated (learned) each time new information on poaching party routes is added to the database. Our second tool provides a real-time sequence of team member moves that maximizes the team’s chances of apprehending a pursued party. We show that our tools perform well when applied to simulated and real data.     

Police use of excessive force: Does the race of the suspect influence citizens' perceptions?

Instances of excessive force by police officers, most notably the Rodney King incident in Los Angeles and the Malice Green fatality in Detroit, suggest that the race of the suspect may influence the decision to use excessive force. If police practices are simply a reflection of the expectations of larger society, then it follows that citizens' evaluations of police brutality toward minorities might reflect this sentiment. As part of a larger study focusing on the exploration of police misconduct, a telephone survey containing 16 vignettes was developed, each vignette described a separate type of misconduct in which a hypothetical officer was involved. Of these 16 vignettes, 3 described the misconduct of excessive force and are analyzed for the present study. A random sample of 992 Ohio citizens were surveyed. The hypothesis that citizens in general assign significantly lower seriousness scores to excessive force on African Americans and Hispanics than on whites was tested. Our hypothesis was not supported. Instead, we found evidence to suggest that the behavior of the suspect during the arrest and the behavior of the police officer are much more significant correlates of citizens' perceptions of police use of excessive force than is the race of the suspect.     

Just enough police presence: Reducing crime and disorderly behavior by optimizing patrol time in crime hot spots

Using observational data collected as part of a one-year preventive patrol study in Minneapolis, this investigation employs survival models to test hypotheses about the effects of specific instances of police patrol presence at high-crime locations on the time until the next occurrence of criminal or disorderly behavior at these locations. The results show that patrol stops must reach a threshold dosage of about 10 minutes in order to generate significantly longer survival times without disorder — i.e., greater residual deterrence — than that generated by driving through a hot spot. The optimal length for patrol stops appears to be 11 to 15 minutes. After that point, continued police presence brings diminishing returns. The theoretical and policy implications of these results are discussed.     

Explaining suspects' resistance and disrespect toward police

The importance of suspects' resistance toward police officers has almost always been described in terms of its influence on police behavior. Given the centrality of citizens' resistance in the literature on police behavior, it is surprising that so little attention has been focused on explaining suspects' resistance independent of its influence on police behavior. This research examined the factors influencing multiple measures of suspects' resistance using systematic observation data collected in 1977 from twenty-four departments in three metropolitan areas. The findings show that non-White suspects were more likely to be noncompliant toward White officers but were not more likely to show more aggressive forms of resistance (e.g., verbal aggression, physical aggression, or disrespect). In addition, female suspects were more likely to be disrespectful toward officers compared to male suspects. The relevance of these findings for future research is discussed.     

“Soft” policing at hot spots—do police community support officers work? A randomized controlled trial

Objectives

To determine whether crime-reduction effects of increased police patrols in hot spots are dependent on the “hard” threat of immediate physical arrest, or whether “soft” patrols by civilian (but uniformed) police staff with few arrest powers and no weapons can also reduce crime. We also sought to assess whether the number of discrete patrol visits to a hot spot was more or less important than the total minutes of police presence across all visits, and whether effects based on counts of crime would be consistent with effects on a Crime Harm Index outcome.

Methods

We randomly assigned 72 hot spots into 34 treatment units and 38 controls. Treatment consisted of increases in foot patrol by uniformed, unarmed, Police Community Support Officers (PCSOs) who carry no weapons and hold few arrest powers beyond those of ordinary citizens. GPS-trackers on every PCSO and Constable in the city yielded precise measurements of all patrol time in all hot spots. Standardized mean differences (Cohen’s d), OLS regression model, and Weighted Displacement Quotient are used to assess main effects, to model the interaction effect of GPS data with treatment, and to measure the diffusion-of-benefits of the intervention, respectively. Outcomes included counts of incidents as well as the Cambridge Crime Harm Index.

Results

As intended, patrol visits and minutes by Police Constables were equal across the treatment and control groups. The sole difference in policing between the treatments groups was in visits to the hot spots by PCSOs, in both the mean daily frequency of discrete visits (T?=?4.65, C?=?2.66; p?≤?.001) and total minutes across all visits (T?=?37.41, C?=?15.92; p?≤?.001), approximately two more ten-minute visits per day in treatment than in control. Main effect estimates suggest 39 % less crime by difference-in-difference analysis of reported crimes compared to control conditions, and 20 % reductions in emergency calls-for-service compared to controls. Crime in surrounding areas showed a diffusion of benefits rather than displacement for treatment hot spots compared to controls. A “Reiss’s Reward” effect was observed, with more proactive patrols predicting less crime across treatment hot spots, while more reactive PCSO time predicted more crime across control hot spots. Crime Harm Index estimates of the seriousness value of crime prevented ranged from 85 to 360 potential days of imprisonment in each treatment group hot spot (relative to controls) by a mean difference of 21 more minutes of PCSO patrol per day, for a potential return on investment of up to 26 to 1.

Conclusions

A crime reduction effect of extra patrols in hot spots is not conditional on “hard” police power. Even small differences in foot patrols showing the “soft power” of unarmed paraprofessionals, holding constant vehicular patrols by Police Constables, were causally linked to both lower counts of crimes and a substantially lower crime harm index score. Correlational evidence within the treatment group suggests that greater frequency of discrete PCSO visits may yield more crime reduction benefit than greater duration of those visits, but RCTs are needed for better evidence on this crucial issue.

     

REDUCING FIREARMS VIOLENCE THROUGH DIRECTED POLICE PATROL*

Research Summary: This evaluation of a directed police patrol project utilizes a pre-post quasi-experimental design with a non-equivalent control group as well as an interrupted time series analysis. The results suggest that directed patrol had an impact on firearms crime in one of the target areas but not the other. Policy Implications: The results suggest that a specific deterrence strategy whereby the police utilize directed patrol to focus on suspicious activities and locations reduced violent gun crime. In contrast, a general deterrence strategy focused on maximizing vehicle stops did not have an apparent effect.     

Hispanic perception of police performance: An empirical assessment

This exploratory study examines relationships between the police and Hispanics in Texas. Specifically, data were collected on Hispanic evaluations of police performance, expectations of police performance, and overall satisfaction with the police. A sample of 500 Hispanics throughout the state of Texas were surveyed on their experienced and perceived relationships with three levels of police agencies: local (municipal) police, sheriff's officers, and the state's Department of Public Safety. Findings are reported based upon overall ratings of the police, victim-related data, and data from individuals who had any form of contact with the police. Significant findings show that any form of contact with the police appeared to lower the rating of police performance. This appears to be a product of the interaction between high public expectations and qualitatively poor police performance. Further findings indicate that an increase in the fear of crime among Hispanics lowered evaluations of local police. Similarly, victimization lowered the evaluation of local police, the county sheriff, and the Department of Public Safety. Hispanics also perceived that officers have a “bad attitude,” that the police need to patrol and investigate more, that response time should be improved, and that there should be less discrimination against Hispanics. These findings appear to be largely influenced by ineffective communication (both symbolic and linguistic) and cultural conflict.
