The Ecology of Police Patrol
Research has demonstrated that police officers have broad understandings of the geographic areas to which they are assigned. These understandings often shape, and are shaped by, interactions between the officer and the community. Numerous researchers have noted the importance of how police conceptualize the space in which they work (Brown 1981; Herbert 1997). Knowledge of dangerous places, situations, or people is shared among officers so that common themes develop among patrol work groups. Klinger (1997) proposes a mediated model that links two factors driving the development of work group norms regarding the vigor used to enforce laws: the workload of the district and the prevalence of other social (noncriminal) problems in a district. The district workload sharply affects the amount of vigor officers are willing to expend on less-serious offenses. Officers in districts with higher workloads will expend less vigor toward less-serious events than officers in districts with lower workloads. Districts that are high in crime are also likely to be high in other noncriminal social problems such as mental illness, homelessness, and alcoholism (Faris 1948).
Although it is not the focus of the present study, it is important to note that scholars have found that certain neighborhoods may be criminogenic despite factors such as turnover in racial/ethnic groups (Stark 1987). As such, police may also have a distinct attitude toward a specific neighborhood on the basis of its reputation. In Klinger’s model, workload and the prevalence of these other social problems drives the development of work group norms. These work group norms develop at the district level of the organizational structure. The variation in workload, community demographics, and environmental factors are the focus of the current study.
Klinger identified several organizational factors that drive the development of stable work groups centered on police patrol. Klinger asserts that these factors, which are consistent across jurisdictions, have to do with how police patrols are organized and how the command structure deals with the activities of the patrol officer. First, police patrol is usually a clearly identifiable group, separate from other branches of the organization. Second, officers generally patrol a district on a semi-permanent basis. Finally, two or more officers usually respond to any incident that may pose a risk to officer safety. This means that officers must work in groups to resolve many situations. The stability of patrol officer work groups and group interaction is important because it builds a district wide shared understanding of the community in which they police.
Turning to work rules, Klinger argues that regardless of the type, structure, or nature of the organizational structure, administrators can provide only limited supervision of patrol officers. Formal rules cannot cope with the complexity of interactions that police are required to handle. Administrators must defer to broad formal mandates regarding the appropriate actions in any particular situation. This leaves patrol officers with a high degree of autonomy regarding the enforcement (or non-enforcement) of laws. Administrators in law enforcement organizations are further hampered by the spatial and temporal distribution of police patrol work. As supervisors get more distant, either organizationally, spatially, or temporally, they have less direct influence over how patrol officers handle any particular situation.
This separation from supervisors does not, however, indicate that individual officers are able to exercise their discretion in isolation from other members of the organization. Although some authors argue that each officer constructs individual styles of policing (Brown 1981; White 1972), Klinger instead argues that a combination of individual and organizational factors determines how patrol work is conducted. Instead, groups of officers conduct negotiations to effectively set rules that allow them to handle situations within the organizational framework.
Klinger’s ecological theory of policing suggests that rule negotiations occur at the district level. These negotiations are based, at least in part, on the understanding of district-level deviance shared among officer work groups. First, districts vary on both the quantity and type of work that an officer may encounter. Officers in high-crime districts tend to be busier than officers in low-crime districts, even after accounting for variations in officer staffing. Second, officers within a district share a common communications system. This shared communication system informs officers how busy their peers are and what types of activities other officers are conducting. Third, how officers perceive district-level deviance is shaped by the public life of residents and visitors in their patrol areas. In high-crime districts, officers are more likely to see criminals in public and are more likely to see crimes committed in public (Klinger 1997). High-crime areas also have a greater proportion of highly visible activities such as prostitution and open-air drug distribution (Rengert et al. 2005; Weisburd et al. 2006).
Klinger’s negotiated order theory is grounded in two theoretical perspectives: stability of punishment and the overload hypothesis. The stability of punishment theory argues that there is a general equilibration in the levels of deviance in a given population over time. In high-crime areas, only highly deviant acts are punished (Durkheim 1938). Acts that would be considered deviant in low-crime areas are seen acceptable in high-crime areas (Moynihan 1993). The overload hypothesis explains the relationship between deviance and quantity of punishment through limitations in the capacity of social control institutions (Geerken and Gove 1975; Geerken and Gove 1977). Increased crime rates strain the capacity of social control institutions, resulting in less energy being devoted to each case, and thereby reducing the certainty of punishment. Both theories predict an inverse relationship between punishment and crime rates: as crime levels increase, the amount of punishment meted out cannot keep pace. Compensation for changing levels of deviance can come from any number of locations throughout the criminal justice system. Klinger (1997) suggests that police patrol officers function as early screeners within this system and that the intensity with which they pursue law enforcement is at least partially contingent upon the prevailing level of crime in an area.
To summarize, Klinger’s ecological theory argues that officer understanding of district deviance is shaped by the district workload, a shared understanding of district deviance, and officers’ observing deviance occurring in public spaces. These understandings are shared among officers within a district because these factors are stable over time and because patrol work tends to be group work. These understandings ultimately form the basis of work group norms.
Negotiated Order in Police Work
The early theoretical framework of negotiated order developed from a study of work groups in two psychiatric hospitals (Strauss et al. 1963). These researchers were concerned with how order could be maintained within the complex organizational framework of the hospital. Traditional rational-bureaucratic theory (Weber 1947) suggested that actors should turn to administratively defined rules and regulations when dealing with complex interactions (Udy 1959). Strauss et al. (1963) identified two limitations with this perspective. First, many actors within the system were not fully aware of all the rules. Second, hospital rules and regulations were neither extensive nor explicit enough to deal with the many situations that personnel encountered. This observation suggested that an organization may have too many rules and, at the same time, these rules may lack the depth necessary to encompass all potential situations an employee can encounter.
The ecological theory of policing uses negotiated order perspective to explain how differences across patrol districts lead to differences in negotiated work group rules. Negotiated rules are determined by environments, mandates, and the work that must be done. The environment is of particular importance because patrol officers become totally immersed in the social and ecological context of their districts (Reiss and Bordura 1967). Klinger (1997) articulates these ideas through four points: normal crime, deservedness of victims, police cynicism, and workload.
First, officers in high-crime districts tend to define deviance downward. These officers bear witness to serious crimes more frequently than officers in lower-crime districts. Officers in high-crime districts, therefore, view disorder-related offenses as normal and not warranting a vigorous police response. As district-level deviance increases, officers will be more likely than their peers in low-crime districts to view more highly serious crime as more normal or acceptable.
Second, officers in both high-crime and low-crime districts believe that many victims bring crime upon themselves and that many victims of crime are themselves criminals. The criminal in one situation can quickly become the victim in another (Lauritsen et al. 1991). Officers believe that when offenders are victimized, they are less worthy of a vigorous police response. As district-level deviance increases, officers will believe that fewer victims of crime are worthy of vigorous police response.
Third, officers in high-crime districts are more cynical than officers in low-crime districts. High-crime areas can be perceived as an indication of a failed criminal justice system. Officers in high-crime districts arrest the same people time and again. These repeated contacts with the same criminals leave officers with the feeling that, regardless of their actions, criminals will be returned to the street and crime will remain high in that district. Officers in high-crime districts deal with this cyclical process to a greater degree than officers in low-crime districts. This increases cynicism and reduces officer vigor.
Finally, districts with a greater workload will be less vigorous in enforcing laws. Officers are aware of the workload in their assigned district; they know that a backlog of calls requiring their attention is likely to occur if they do not deal with events efficiently. The ultimate decision for the officer rests upon how much time, effort, or resources should be devoted to any particular case. These decisions are made even more important by the organizational management structure. Officers have greater autonomy in incident disposition than they do in work quantity assigned. In these situations, officers have incentives to focus on more serious crimes and reduce the amount of time spent on minor crimes (Lipsky 1980).
There are two exceptions to these negotiations. First, homicide always results in vigorous police actions, regardless of other situational or organizational factors. Second, events threatening officer safety will always receive vigorous police actions. These events are never considered normal; they always result in the most vigorous law enforcement efforts.
Evaluations of Negotiated Order in Patrol Work
An extensive literature search reveals only a few studies aimed directly at assessing the key points of Klinger (1997) theory. The first of these studies, Hassell (2005), shed a great deal of light on many of Klinger’s key postulates. The study was conducted (using field work, interviews, and administrative data) in an undisclosed Midwestern city police department with 760 sworn police officers. Hassell found only limited support for a number of Klinger’s key theoretical components. Numerous key predictions were not supported by the findings. Hassell (2005) concluded that the general causal model demonstrated utility in analyzing police activity. Perhaps most importantly, police patrol practices did demonstrate substantial variation at the district level. As such, the district level was a valid aggregate unit for study. The more specific and nuanced predictions made by the model, however, were unsupported by the findings.
More recently, Sobal (2010a) examined if Klinger’s theory of negotiated order could be used to explain whether district crime and deviance levels shape police attitudes toward residents. Sobal’s study used data from the Project on Policing Neighborhoods (POPN), which collected data from two cities, Indianapolis, IN, and St Petersburg, FL. These data included social observations, census data, police crime records, interviews with officers. Controlling for individual and organizational factors, Sobal found that district crime rates did influence levels of police cynicism. Officers assigned to higher-crime districts had higher levels of cynicism. Sobal also found that officers with more experience had lower levels of cynicism. Sobal’s findings provide support for Klinger’s argument that district crime levels influence levels of police cynicism.
In another study, Sobal (2010b) used the POPN to conduct a partial test of Klinger’s theory, specifically focusing on officer cynicism and workload and how they influence the vigor of police response. The results of the study found little influence of cynicism and district workload on the crime/vigor relationship as proposed by Klinger. These results suggest that other factors may be influencing the crime/vigor relationship.
While Sobal’s studies represent an important step in the testing of Klinger’s work, there is a need for continued study of Klinger’s theory. The present study provides an additional test of Klinger’s theory from a different perspective than that of Sobal, exploring whether it is possible to measure the relationship between officer staffing and the quantity of “work” produced. Furthermore, the present study also provides a test of Sobal’s work and may help clarify his findings, and it also adds a temporal component to the analysis that other studies have not included.
The Effects of Neighborhoods on Policing
Broadening the scope of relevant research produces numerous studies that have considered the relationship between community sociostructural factors and the police. With few exceptions, researchers have found that neighborhood characteristics have a substantial impact on police activity.Footnote 2 The effects of neighborhoods and underlying sociodemographic characteristics cannot be overestimated (Bayley and Mendelsohn 1969). This finding has important implications for Klinger’s theory. The true nature of police vigor will be most manifest in situations that have the most situational ambiguity. Therefore, an analysis of patrol officer vigor is most likely to result in variation in regard to acts that are considered less serious. We are most likely to see variations in the application of vigor for events that are of a less serious nature, and this variation will be based on the factors laid out in Klinger’s theory.
Reiss and Bordura (1967) argue that informal practices in police departments allow officers to vary their use of formal authority depending on the position of the social group involved—and specifically that police may accept higher levels of crimes among disadvantaged minority communities. If this premise is true, the relationship may manifest itself in a manner consistent with predictions under the ecological theory of policing.
With rare exceptions, such as Slovak (1986), the literature has consistently shown that community factors affect where and how police services are delivered (Terrill and Reisig 2003). For example, Terrill and Reisig sought to examine the effect of neighborhood on police use of force. Using data from the POPN, social observations, census data, police crime records, and interviews with officers, Terrill and Reisig (2003) found support for the notion that neighborhood influences police use of force, with police being more likely to use higher levels of force in neighborhoods with greater levels of disadvantage. Underlying the discussion of how police services are delivered is the idea that police operate with a great deal of discretion.
