Shaping Citizen Perceptions of Police Legitimacy: A Randomized Field Trial of Procedural Justice

Exploring the relationship between procedural justice and citizen perceptions of police is a well‐trodden pathway. Studies show that when citizens perceive the police acting in a procedurally just manner—by treating people with dignity and respect, and by being fair and neutral in their actions—they view the police as legitimate and are more likely to comply with directives and cooperate with police. Our article examines both the direct and the indirect outcomes of procedural justice policing, tested under randomized field trial conditions. We assess whether police can enhance perceptions of legitimacy during a short, police‐initiated and procedurally just traffic encounter and how this single encounter shapes general views of police. Our results show significant differences between the control and experimental conditions: Procedurally just traffic encounters with police (experimental condition) shape citizen views about the actual encounter directly and general orientations toward the police relative to business‐as‐usual traffic stops in the control group. The theorized model is supported by our research, demonstrating that the police have much to gain from acting fairly during even short encounters with citizens.     

DRIVING WHILE BLACK: EFFECTS OF RACE,ETHNICITY, AND GENDER ON CITIZEN SELF‐REPORTS OF TRAFFIC STOPS AND POLICE ACTIONS*

Are African‐American men, compared with white men, more likely to report being stopped by police for traffic law violations? Are African‐American men and Hispanic drivers less likely to report that police had a legitimate reason for the stop and less likely to report that police acted properly? This study answers these questions using citizen self‐reports of their traffic stop encounters with the police. Net of other important explanatory variables, the data indicate that police make traffic stops for Driving While Black and male. In addition, African‐American and Hispanic drivers are less likely to report that police had a legitimate reason for the stop and are less likely to report that police acted properly. The study also discusses the validity of citizen self‐report data and outlines an agenda for future research.     

Assessing the effects of body‐worn cameras on procedural justice in the Los Angeles Police Department*

In this article, we explore variations in procedural justice delivered in face‐to‐face encounters with citizens before and after the implementation of body‐worn cameras (BWCs). We draw on recent advances in the measurement of procedural justice using systematic social observation of police in field settings in the Los Angeles Police Department. Data collected on 555 police–citizen encounters are examined in bivariate and multivariate models exploring the primary hypothesis that BWCs affect procedural justice delivered by police directly and indirectly. Our results indicate that significant increases in procedural justice during police–citizen encounters were directly attributable to the effect of BWCs on police behavior as well as to the indirect effects on citizen disrespect and other variables. The implications for policy include explicit measurement and monitoring of procedural justice or elements such as officer discourtesy in departments adopting BWCs. Further research questions such as more detailed examination of citizens’ behavior changes under BWCs are also considered in the context of the findings.     

Is It the What or the How? The Roles of High‐Policing Tactics and Procedural Justice in Predicting Perceptions of Hostile Treatment: The Case of Security Checks at Ben‐Gurion Airport,Israel

What affects perceptions of hostile treatment by police, characterized by feelings such as humiliation and intimidation? Is it what the police do to the citizen, or is it about how they do it? The important effects of procedural justice are well documented in the policing literature. Yet, it is not clear how high‐policing tactics, coupled with procedural justice, affect one's sense of hostile treatment: is it the case that what the police do does not matter as long as they follow the principles of procedural justice, or do some invasive or unpleasant tactics produce negative emotions regardless of the amount of procedural justice displayed by the officer? In the present study we examine this question in the context of security checks at Ben‐Gurion Airport, Israel. Using a survey of 1,970 passengers, we find that the behavioral elements of procedural justice are an important antidote, mitigating the negative effects of four “extra” screening measures on the perceived hostility of the checks. At the same time, two security measures retain an independent and significant effect. We discuss the implications of our findings and hypothesize about the characteristics of policing practices that are less sensitive to procedural justice.     

Procedural justice and police legitimacy: a systematic review of the research evidence

Objectives

We undertook a systematic review and meta-analysis to synthesize the published and unpublished empirical evidence on the impact of police-led interventions that use procedurally just dialogue focused on improving citizen perceptions of police legitimacy.

Methods

The systematic search included any public police intervention where there was a statement that the intervention involved police dialogue with citizens that either was aimed explicitly at improving police legitimacy, or used at least one core ingredient of procedural justice dialogue: police encouraging citizen participation, remaining neutral in their decision making, conveying trustworthy motives, or demonstrating dignity and respect throughout interactions. The studies included in our meta-analyses also had to include at least one direct outcome that measured legitimacy or procedural justice, or one outcome that is common in the legitimacy extant literature: citizen compliance, cooperation, confidence or satisfaction with police. We conducted separate meta-analyses, using random effects models, for each outcome.

Results

For every single one of our outcome measures, the effect of legitimacy policing was in a positive direction, and, for all but the legitimacy outcome, statistically significant. Notwithstanding the variability in the mode in which legitimacy policing is delivered (i.e., the study intervention) and the complexities around measurement of legitimacy outcomes, our review shows that the dialogue component of front-line police-led interventions is an important vehicle for promoting citizen satisfaction, confidence, compliance and cooperation with the police, and for enhancing perceptions of procedural justice.

Conclusions

In practical terms, our research shows the benefits of police using dialogue that adopts at least one of the principles of procedural justice as a component part of any type of police intervention, whether as part of routine police activity or as part of a defined police crime control program. Our review provides evidence that legitimacy policing is an important precursor for improving the capacity of policing to prevent and control crime.     

Procedural Justice and Order Maintenance Policing: A Study of Inner‐City Young Men’s Perceptions of Police Legitimacy

There is tension between the core tenets of procedural justice and those of order maintenance policing. Research has shown that citizens’ perceptions of procedural justice influence their beliefs about police legitimacy, yet at the same time, some order maintenance policing efforts stress frequent stops of vehicles and persons for suspected disorderly behavior. These types of programs can threaten citizens’ perceptions of police legitimacy because the targeted offenses are minor and are often not well‐defined. Citizens stopped for low‐level offenses may view such stops as a form of harassment, as they may not believe they were doing anything to warrant police scrutiny. This paper examines young men’s self‐described experiences with this style of proactive policing. Study findings highlight that order maintenance policing strategies have negative implications for police legitimacy and crime control efforts via their potential to damage citizens’ views of procedural justice.     

Procedural justice policing and citizen compliance behaviour: the importance of emotion

Research consistently finds that if authorities use procedural justice in encounters with the public then this will promote citizen cooperation and compliance with the law. Recently, the importance of people's emotional reactions in response to procedural justice and injustice, and the subsequent effect this has on behaviour have been examined. This paper utilises a multi-method approach to examine the mediating role that negative affect plays in the effect of procedural justice policing on citizen compliance behaviour. Study 1 utilises both cross-sectional and longitudinal field survey data collected from Australian citizens who have had a recent contact with a police officer. Study 2 utilises an experimental vignette study designed to assess the causal mechanisms involved in the procedural justice–emotion–compliance relationship. Both studies find that procedural justice is linked to people's self-reported propensity to comply with police. Study 1 and 2 also find that negative affect mediates this relationship. These findings have important implications for training police to interact with the public in a manner that reduces negative emotions and ensures the highest level of compliance from the public.     

Police Legitimacy and Citizen Cooperation in China: Testing an Alternative Model

Past research has identified several mechanisms of promoting citizen cooperation with the police, with Tyler’s process-based policing model being one of the most frequently tested frameworks in this line of inquiry. Using data collected from a large sample of residents in a large Chinese city, this study assesses an alternative model of Tyler’s work proposed by Tankebe (2013), positing that police legitimacy, embodied in four aspects of procedural justice, distributive justice, effectiveness, and lawfulness, affects people’s obligation to obey the police, which further influences their cooperation with the police. Results from second-order confirmatory factor analysis and structural equation modeling analysis suggested that Tankebe’s work is supported by the Chinese data. Implications for future research and policy are discussed.     

The influence of strain on law enforcement legitimacy evaluations

Purpose

While law enforcement officers have the state-sanctioned authority to use force as a way to ensure citizen obedience with the law, research has found that when private citizens evaluate the police as legitimate, they are more likely to comply with legal demands and cooperate with the police. Although procedural justice has shown to be a highly significant predictor of perceived police legitimacy, research has found other correlates of this outcome, including ethnic identity, low self-control and structural economic disadvantage. To date, no study has explored whether strain influences perceptions of the legitimacy of law enforcement.

Methods

A series of linear regression equations was estimated using survey data collected from a convenience sample of college students to determine the effect of strain on perceived police legitimacy.

Results

Even after controlling for procedural justice, strain exerted a negative and statistically significant influence on law enforcement legitimacy evaluations.

Conclusions

Police officers are encouraged to interact with citizens in procedurally just manners and to also consider people's strain levels when enforcing the law.     

Is the Effect of Procedural Justice on Police Legitimacy Invariant? Testing the Generality of Procedural Justice and Competing Antecedents of Legitimacy

Objectives

This study tests the generality of Tyler’s process-based model of policing by examining whether the effect of procedural justice and competing variables (i.e., distributive justice and police effectiveness) on police legitimacy evaluations operate in the same manner across individual and situational differences.

Methods

Data from a random sample of mail survey respondents are used to test the “invariance thesis” (N = 1681). Multiplicative interaction effects between the key antecedents of legitimacy (measured separately for obligation to obey and trust in the police) and various demographic categories, prior experiences, and perceived neighborhood conditions are estimated in a series of multivariate regression equations.

Results

The effect of procedural justice on police legitimacy is largely invariant. However, regression and marginal results show that procedural justice has a larger effect on trust in law enforcement among people with prior victimization experience compared to their counterparts. Additionally, the distributive justice effect on trust in the police is more pronounced for people who have greater fear of crime and perceive higher levels of disorder in their neighborhood.

Conclusion

The results suggest that Tyler’s process-based model is a “general” theory of individual police legitimacy evaluations. The police can enhance their legitimacy by ensuring procedural fairness during citizen interactions. The role of procedural justice also appears to be particularly important when the police interact with crime victims.

     

Perceived police legitimacy: investigating its association with college-based informal social controls

Research has found that when private citizens view law enforcement as legitimate authority figures, they are more likely to obey laws and voluntarily comply with police demands. Although procedural justice has shown to be an important predictor of perceived police legitimacy, a recent line of studies has found other significant correlates of this outcome, including media exposure, ethnic identity and strain. To date, however, few studies have explored the role collegiate-based informal social controls play in predicting law enforcement legitimacy evaluations. Using questionnaire data from a convenience sample of college students, linear regression equations were estimated to explore whether Hirschi's four social bond measures predict the obligation to obey and trust in police constructs of police legitimacy. Across both models and even after controlling for procedural justice, respondent beliefs were positively correlated with these measures. Theoretical and policy implications are discussed.     

Informal Social Controls,Procedural Justice and Perceived Police Legitimacy: Do Social Bonds Influence Evaluations of Police Legitimacy?

Although procedural justice has been a key predictor of police legitimacy, recent findings illustrate that other factors influence this outcome (i.e., low self-control and ethnic identity). However, no research to date has evaluated whether individual-level informal social controls impact police legitimacy evaluations. Survey data are used to examine the influence of parental attachment, school commitment and procedural justice on perceived police legitimacy. While procedural justice significantly predicted legitimacy evaluations, no significant relationships were observed between parental attachment, school commitment and police legitimacy. The effects of procedural justice on legitimacy assessments, however, were modestly significantly moderated by parental attachment and school commitment. To maintain legitimacy, police officers should interact with citizens in procedurally fair manners. These results should also be of value concerning how parents and schools legally socialize adolescents.     

Procedural Justice and Police Legitimacy: A Test of Measurement and Structure

The procedural justice theory of police legitimacy has received substantial empirical support, yet too little attention has been paid to the operationalization and measurement of these important theoretical constructs. In particular, it is unclear whether the items used to represent procedural justice and police legitimacy possess convergent and discriminant validity. The current study uses confirmatory factor analysis to test for the measurement properties of these constructs and expands upon prior research by also including a measure of encounter-based procedural justice in addition to a scale tapping into global beliefs. The results provide mixed support for discriminant and convergent validity between legitimacy and global procedural justice. Full structural equation models test an alternative specification of one of the popular measurement methods for legitimacy, and compare the relative impact of each type of procedural justice. The findings indicate that while specific procedural justice predicts legitimacy, global procedural justice has a stronger influence. Implications for measurement and police policy are discussed.     

Challenging the ‘invariance’ thesis: procedural justice policing and the moderating influence of trust on citizens’ obligation to obey police

Objectives

This paper examines the effects of a procedural justice policing intervention on citizens’ feelings of obligation to obey police. It examines whether the efficacy of procedural justice on citizens’ obligation to obey police may be contingent on citizens’ level of trust in police during a police–citizen encounter.

Methods

This research draws on survey data from the Queensland Community Engagement Trial (QCET). QCET was a randomized controlled field trial implemented by the Queensland Police Service. The trial exposed citizens to either a procedural justice experience (experimental condition) or standard police practice (control condition) during a random roadside stop. Survey responses were received from 1107 drivers in the experimental condition and 1655 drivers in the control condition.

Results

Compared to the control condition, the procedural justice condition yielded higher levels of trust in the police officer conducting the roadside stop. No differences in obligation to obey police were observed between the two conditions. Importantly, citizens’ level of trust in the officer moderated the effect of the intervention on obligation to obey police. Specifically, the procedural justice condition had a negative effect on obligation to obey for those reporting low trust in police. For those high in trust, the procedural justice intervention had a slight but insignificant positive effect on obligation to obey.

Conclusions

The findings suggest that procedural justice effects can vary between individuals; specifically, the findings reveal that procedural justice interventions can sometimes be counter-productive, depending on the level of trust a citizen exhibits toward police during an encounter. Police agencies should therefore be aware of potential counter-productive effects when implementing procedural justice in the field.

     

Examining macro-level impacts on procedural justice and police legitimacy

Purpose

Many studies have lent empirical support to the procedural justice model of police legitimacy; however, there has, as yet, not been widespread consideration of the potential impact of neighborhood- and community-level factors on people's perceptions of procedural justice or police legitimacy. The present study integrates the macro-level policing literature with the psychological-based procedural justice framework to uncover what effects, if any, the sociostructural environment has on procedural justice and police legitimacy.

Methods

Hierarchical linear modeling integrates census and survey data within a single, mid-sized city.

Results

Concentrated disadvantage exerted a marginally-significant impact on procedural justice, and on police legitimacy while controlling for procedural justice. Procedural justice remained the strongest predictor of legitimacy, even when accounting for macro-level characteristics.

Conclusions

The effect of procedural justice on police legitimacy appears to be robust against the deleterious impacts of concentrated disadvantage. This has implications for procedural justice research, theory, and policing.     

Revisiting the role of distributive justice in Tyler’s legitimacy theory

Objectives

Tyler’s theory of legitimacy identified procedural justice and distributive justice as antecedents of legitimacy, but placed distributive justice in a relatively minor position compared with procedural justice. This has led to researchers paying less attention to distributive justice in the development of theory, despite consistent findings that distributive justice is important to a number of outcomes for criminal justice authorities. This report uses uncertainty management theory to revisit Tyler’s legitimacy model and gain a more nuanced understanding of distributive justice.

Methods

The proposed model is tested using a series of latent variable analyses conducted on a sample of 2169 adults and a factorial vignette design. The vignette design randomly manipulates outcome favorability and officer behavior during a hypothetical traffic stop. Multiple indicator multiple cause (MIMIC) models are then utilized to test the impact of these manipulations on perceptions of procedural justice and distributive justice. This is followed by a structural equation model that tests the relationships between procedural justice, distributive justice, and legitimacy.

Results

Officer behavior is a primary predictor of both procedural justice and distributive justice. Furthermore, the results demonstrate that distributive justice judgments are shaped by perceptions of procedural justice. Accordingly, distributive justice mediates the relationship between procedural justice and legitimacy.

Conclusions

Distributive justice should not be treated as a competing explanation for legitimacy evaluations, but as a concept that contextualizes why procedural justice is important.

     

Procedural justice during police-citizen encounters: The effects of process-based policing on citizen compliance and demeanor

Purpose

Theories of procedural justice have facilitated the development of a process-based approach to policing which emphasizes the fairness of the manner in which the police exercise their discretion. The study examines whether procedurally fair behavior by the police affects two types of citizen behavior during encounters: citizen disrespect toward the police and citizen noncompliance with police requests.

Methods

This study uses data from systematic social observations of police-citizen encounters to examine procedural justice factors on citizen behavior. Because of the reciprocal nature of police-citizen interactions, an instrumental variable is used in the statistical analysis to help address the causal relationship between police force and citizen disrespect.

Results

The statistical analyses find limited support for procedural justice factors. Two types of procedurally fair behavior by the police, police demeanor and their consideration of citizen voice, are significant in reducing citizen disrespect and noncompliance, respectively.

Conclusion

Procedural justice factors have limited and inconsistent impacts on the two types of citizen behavior, and future research should address the limitations of this study and evaluate process-based policing with more data from social observations of police-citizen encounters.     

“It Depends on the Outcome”: Prisoners,Grievances, and Perceptions of Justice

Social scientists have long investigated the social, cultural, and psychological forces that shape perceptions of fairness. A vast literature on procedural justice advances a central finding: the process by which a dispute is played out is central to people's perceptions of fairness and their satisfaction with dispute outcomes. There is, however, one glaring gap in the literature. In this era of mass incarceration, studies of how the incarcerated weigh procedural justice versus substantive justice are rare. This article addresses this gap by drawing on unique quantitative and qualitative data, including face‐to‐face interviews with a random sample of men incarcerated in three California prisons and official data provided by the California Department of Corrections and Rehabilitation (CDCR). Our mixed‐methods analysis reveals that these prisoners privilege the actual outcomes of disputes as their barometer of justice. We argue that the dominance of substantive outcomes in these men's perceptions of fairness and in their dispute satisfaction is grounded in, among other things, the high stakes of the prison context, an argument that is confirmed by our data. These findings do not refute the importance of procedural justice, but show the power of institutional context to structure perceptions of and responses to fairness, one of the most fundamental principles of social life.     

Understanding non-coercive,procedurally fair behavior by the police during encounters

Theories of procedural justice have emphasized the importance of non-coercive police behavior during encounters in obtaining citizen compliance and promoting police legitimacy. In the empirical research on police behavior, however, non-coercive police behavior has not been examined extensively. With social observations of police–citizen encounters, this study explored the correlates of police initiated non-coercive behavior (such as care, assistance, and advice/requests) in situations involving domestic and non-domestic conflicts. The non-coercive behavior was also examined in comparison with coercive behavior (such as use of verbal force, use of physical force, and arrest). The analyses found that police officers behaved differently in two types of situations, and that citizens’ characteristics such as gender, class, and demeanor had significant impacts on non-coercive police behavior. Implications for understanding police behavior and handling domestic conflict situations are also discussed.
