The purpose of this paper is to describe how the Philadelphia Police Department instituted a large‐scale randomized controlled trial of foot patrol as a policing strategy and experienced 23 percent fewer violent crimes during the treatment period. The authors examine whether activities patrol officers were conducting might have produced the crime reduction. The activities of foot and car patrol officers research takes a closer look at what types are examined separately and differences between car patrol activities pre‐intervention and during the intervention are explored. Activities of foot versus car patrol officers during the study period are compared across treatment and control areas.

Official data on police officer activity are used to compare activities conducted by foot patrol officers with those by car patrol officers in 60 treatment (foot beat) and 60 control areas consisting of violent crime hot spots. Activities of car patrol officers are described pre‐intervention and during the intervention. Foot patrol officers’ activities are described within treatment and control areas during the treatment phase of the experiment. Car patrol officers’ activities are reported separately. The statistical significance of changes in car patrol activity pre and during intervention is evaluated using a series of mixed model ANOVAs.

There were noticeable differences in the activities conducted by foot and car patrol. Foot patrol officers spent most of their time initiating pedestrian stops and addressing disorder incidents, while car patrol officers handled the vast majority of reported crime incidents. Car patrol activity declined in both treatment and control areas during the intervention but there was no statistically significant difference between the treatment and the control areas.

The major limitation of this study is the restricted set of data describing officer activity that is captured by official records. Future studies should include a more robust ethnographic component to better understand the broad spectrum of police activity in order to more effectively gauge the ways in which foot patrol and car‐based officers’ activities interact to address community safety. This understanding can help extend the literature on “co‐production” by highlighting the safety partnerships that may develop organically across individual units within a police organization.

The study provides evidence that individual policing strategies undertaken by agencies impact one another. When implementing and evaluating new programs, it would be beneficial for police managers and researchers to consider the impact on activities of the dominant patrol style, as necessary, to understand how a specific intervention might have achieved its goal or why it might have failed to show an effect.

The research contributes to the understanding of the separate and joint effects of foot and car patrol on crime. In addition, it provides police managers with a clearer picture of the ways in which foot patrol police and car‐based officers work to co‐produce community safety in violent inner‐city areas.

The purpose of this paper is to provide information on the activities of police bicycle patrols.

A participant/observation research design was used. A five‐city, 32‐shift study on the output of police bicycle patrols was conducted. Same and similar ride‐alongs were conducted with bicycle and automobile patrols. All contacts (n=1,105) with the public were recorded and coded. These data included: number of people, tenor, seriousness and origination for each contact.

Analysis of these data provides evidence that bicycle patrols result in over twice as much contact with the public compared with automobile patrols. The field observation perspective revealed clear tactical advantages to bicycle patrols.

With a limited prior study of a police bicycle patrol's activities, this study is a significant initial step.

With evidence of tactical and numerical public contact advantages, more attention and resources aimed at deployment of police bicycle patrols appear to be warranted.

With large US cities and other departments using bicycle patrols, preliminary information on effectiveness appears to be both original and of value.

The purpose of this paper is to use an evaluation of a micro-place-based hot-spot policing implementation to highlight the potential issues raised by data quality standards in the recording and measurement of crime data and police officer movements.

The study focusses on an area of London (UK) which used a predictive algorithm to designate micro-place patrol zones for each police shift over a two-month period. Police officer movements are measured using GPS data from officer-worn radios. Descriptive statistics regarding the crime data commonly used to evaluate this type of implementation are presented, and simple analyses are presented to examine the effects of officer patrol duration (dosage) on crime in micro-place hot-spots.

The results suggest that patrols of 10-20 minutes in a given police shift have a significant impact on reducing crime; however, patrols of less than about 10 minutes and more than about 20 minutes are ineffective at deterring crime.

Due to the sparseness of officer GPS data, their paths have to be interpolated which could introduce error to the estimated patrol dosages. Similarly, errors and uncertainty in recorded crime data could have substantial impact on the designation of micro-place interventions and evaluations of their effectiveness.

This study is one of the first to use officer GPS data to estimate patrol dosage and places particular emphasis on the issue of data quality when evaluating micro-place interventions.

The purpose of this study is to examine whether patrol officers believe that police practices vary by precinct assignment and whether the precinct acts as a sub‐organizational level of analysis in police organizations.

The research design is a multi‐method ethnographic case study including observational fieldwork, both structured and unstructured interviews and official departmental documents.

The study finds that patrol officers overwhelmingly agree that police practices vary at the precinct level of analysis. This variation is perceived to be caused by: individual officer temperament/personality and level of experience,; culture, nature and expectations of the clientele/citizens; nature of calls for service, higher call loads and officer safety concerns; and command and precinct rules/norms. The study also finds that the precinct is a viable and important level of analysis within police organizations.

This study highlights the need to examine variation in police behavior within organizations at the precinct level of analysis.

The findings from this study have considerable practical implications because the findings indicate that to understand police patrol practices, police practitioners must investigate variation in the informal structures/cultures of police organizations at the sub‐organizational level of the precinct.

This paper is valuable because police researchers have investigated police behavior at the individual, situational, neighborhood, organizational and legal levels of analyses but have largely overlooked the intersection of these levels of analyses: the precinct.

This article seeks to look at the police officer on patrol. It aims to explore three categories of work undertaken during periods of un‐tasked patrol where officers can self‐direct their work.

Informed by empirical data from an ethnographic study of front line community policing in Britain, the categories of work are illustrated through the profile(s) of officer(s) whose actions best support each style.

The coming together of officers with different skills and the propensity to undertake different types of police work can broaden the community policing philosophy as well as the practice itself. While an expansive policing mandate can be used to justify and explain the pursuit of preferential areas of police work by the patrolling officer, findings also uncover evidence of the persistence of police practices and attitudes that alienate certain community groups.

Given the sustained popularity of localized policing models, further ethnographies are needed to broaden the analysis of patrol work particularly as additional research of this kind conducted with different groups of officers may well reveal evidence of different patrol styles.

If the full potential of community policing is to be recognized then the police service needs to encourage front line officers to devise ways of learning about, making contact with, and working with, the diverse groups that comprise local communities. However, introducing new policies and working practices needs to be accompanied by attitudinal and behavioural change.

The paper presents a new and original set of patrolling styles of the police officer.

Examines the link between level of organizational commitment and patrol officers’ attitudes toward and participation in police occupational deviance in a police patrol bureau. Uses analysis and interpretation of qualitative data gathered during field research in one mid‐sized police department to develop the subject. Field research was conducted over a seven‐month period, during which 580 hours of field observations were made and 48 unstructured interviews with patrol officers were conducted. Analysis disclosed that patrol officers with low levels of organizational commitment tended to engage in patterns of work avoidance and manipulation and employee deviance against the organization ‐ in contrast, patrol officers with high levels of commitment to the organization were likely to engage in employee deviance against the organization. Finally, patrol officers with a medium level of organizational commitment engaged in any of the three forms of deviance, depending on which end of the commitment continuum they tended toward. Claims that all patrol officers accepted informal rewards.

The purpose of this paper is to investigate the impact of a police foot patrol considering micro-geographic units of analysis.

Six years of monthly crime counts for eight violent and property crime types are analyzed. Negative binomial and binary logistic regressions were used to evaluate the impact of the police foot patrol.

The impact of police foot patrol is in a small number of micro-geographic areas. Specifically, only 5 percent of the spatial units of analysis exhibit a statistically significant impact from the foot patrol.

These analyses show the importance of undertaking evaluations at the micro-scale in order to identify the impact of police patrol initiative because a small number of places are driving the overall result. Moreover, care must be taken with how small the units of analysis are because as the units of analysis become smaller and smaller, criminal events become rarer and, potentially, identifying statistically significant change becomes more difficult.

The purpose of this paper is to detail the prevalence and nature of patrol officers' alcohol‐related workload.

A systematic social observation (SSO) methodology was used to collect data pertaining to the alcohol‐related activities and encounters of patrol officers. A fully randomized sampling procedure was used to select the days, times, and geographic areas of observation sessions. Observational data were obtained for 65 separate observations sessions ‐ totaling approximately 650 hours, 480 police‐citizen encounters, with 766 citizens, and 2,009 non‐encounter activities.

Approximately 26 percent of encounters and 10 percent of non‐encounter activities involved citizen alcohol use. Roughly 15 percent of patrol officer time is dedicated to alcohol‐related encounters and their associated activities. Alcohol‐related encounters were of a substantively different type than those in which there was no alcohol involvement. In sum, alcohol‐related encounters were more likely to involve a crime, occur in emotionally volatile situations, elicit a multiple‐officer response, and to take place out of the public sphere.

The paper demonstrates the utility of police‐researcher collaboration. The findings can make a direct contribution to academy and in‐service training.

Unlike previous SSO studies, this research used data obtained from a representative sample of police patrols. The use of a SSO protocol provides a level of detail about the nature of police‐citizen interactions within the context of alcohol‐related encounters not previously seen in the literature.

The purpose of this paper is to examine national survey data of police agencies in the USA to explore the current state of crime analysis integration to patrol crime reduction work.

The data examined in this paper are from a national quantitative survey which sought to understand how crime analysis results are used by officers as well as higher ranking personnel in the patrol division and what types of strategies are implemented using crime analysis.

The findings show that the routine use of crime analysis is not well integrated. Despite the low integration, however, some differences were found. Management uses crime analysis the most overall, but officers and first-line supervisors use tactical crime analysis more routinely than management, where management personnel use evaluation most routinely. Tactical crime analysis is used most often for directed patrol, strategic for both directed patrol and general information, and evaluation for both general information and crime prevention. Analysis of using analysis proactively shows that agencies use tactical crime analysis most proactively, followed by the strategic crime analysis, then evaluation.

The study relies on self-report surveys, so the results may suffer from some of the general limitations of self-reports. Also, the study resulted in a lower response rate than surveys of police agencies typically achieve. Although responding and non-responding agencies were comparable in terms of population size, number of officers, and region of the country, the response rate was about 55 percent. However, it is a possibility based on the analysis results that non-responses may reflect a disinterest in the topic or the lack of integration of crime analysis.

This is the first national survey that focussed specifically on crime analysis integration in patrol work for crime reduction. The value of the results presented here are in the description of the current state of crime analysis integration in the USA which has not been investigated in such depth before and the identifications of gaps in both research in practice.
