The article presents research results of an ethnographic survey within the German police. The focus is on practices of spatial production and the functions of spaces.

The article draws on data from the DFG-funded research project KORSIT (Social Construction of security-related Spaces) based on an ethnographic survey in the German police force (https://www.dhpol.de/korsit). Participant observations were conducted in police stations in two large German cities (pseudonymised as “Dillenstadt” and “Rosenberg”). It involved 60 guided interviews with police officers at different levels of the hierarchy, as well as further interviews with local and societal actors for contrasting purposes. The data was analysed on the basis of grounded theory (Strauss and Cobin, 1996).

This paper shed light on institutional spatial knowledge, which is the basis of police practices, is preceded by experience-based narratives. In an expanded perspective, the paper argues that urban spaces themselves can be understood as materialisations of social practices that serve as social demarcation that legitimise unequal styles of action in the different precinct within the German police. In terms of a relational conceptualisation of space, it is shown that the categories of ethnicity and gender interrelate within the institutional production of space.

The article links organisational research with sociological spatial research and provides basic explanatory models on the conditions of emergence and the persistence of discriminatory practices within the police.

Based on the theoretical viewpoints of criminal geography and environmental criminology, this research uses spatial multi-criteria decision-making methods. In the process of spatial decision-making and optimization of police resources, researchers fully consider the dynamic application of Geographic Information System (GIS) and the effects of spatial prevention and control.

Researchers use an integrated method combining Policing Geographic Information System (PGIS) and multi-criteria decision analysis (MCDA). On the one hand, police GIS has an excellent visual data analysis platform and integrated decision support system in data management, spatial analysis, data exploration and regression analysis. On the other hand, through the design of the indicator system, the quantification of indicators, the determination of weights, comprehensive evaluation and sensitivity analysis, MCDA can select the best plan from a large number of alternatives. When joining MCDA, the spatial dimension will bring the research results closer to the real world.

The study finds that the crime of burglary is affected to a certain extent by the distribution of police forces, the location of police units. Another important finding of this research is the correlation between more precise preventive measures and the crime of burglary.

From a practical point of view, this research would help advance the role of police units and law enforcement agencies in preventing burglary crimes and provide experience for the allocation of regional police resources.

The purpose of this paper is to examine the spatial influence of features of the physical environment on the risk of aggression toward law enforcement.

The spatial analytic technique, risk terrain modeling was performed on felonious battery data provided by the Chicago Police Department.

Out of the 991 batteries against law enforcement officers (LEOs) in Chicago, 11 features of the physical environment were identified as presenting a statistically significant spatial risk of battery to LEOs. Calls for service within three blocks of foreclosures and/or within a dense area of problem buildings pose as much as two times greater risk of battery to police officers than what is presented by other significant spatial factors in the model.

An abundance of existing research on aggression toward law enforcement is situated from the perspective of characteristics of the suspect or officer. The research advances the field of violence studies by illustrating the importance of incorporating physical features of the environment into empirical studies of aggression.

A strong body of research has established the concentration of crime in a small number of street segments or “hot spots” throughout urban cities, but the spatial distribution of mental health-related calls for services is less well known. The extent to which these calls are concentrated on a small number of street segments, similar to traditional crime calls for service is understudied. The purpose of this paper is to examine the concentration of mental health calls and the spatial distribution of street segments with mental health calls to provide directions for law enforcement and place-based policing.

Using call for service data from a large city on the East coast, the current study examines whether mental health calls for service are concentrated on street segments, and tests spatial dispersion to whether these “mental health hot spots” are spread throughout the city or clustered in space. Finally, the authors explore the relationship between mental health calls and violent and drug calls by calculating the correlation and using a spatial point pattern test to determine if mental health calls are spatially similar to violent and drug calls.

The authors found that mental health calls are concentrated on street segments; specifically 22.4 percent of calls are located on 0.5 percent of city street segments. Additionally, these street segments are fairly dispersed throughout the city. When comparing the spatial similarity of mental health calls to violent and drug calls, they are highly correlated suggesting a relationship between the calls types, but the location of mental health calls appears to be different from violet and drug calls.

Very few studies have examined the location of mental health calls and whether they are concentrated in small areas similar to crime, but such research can provide police officers new approaches to working with people with mental health problems. The police are the primary emergency response for calls involving someone with a mental illness or experiencing a mental health crisis and the authors provide suggestions for policing that draw from strategies used in hot spot policing and mental health responses, like CIT, to address challenges of modern policing and working with people with mental health problems.

Aside from a few groundbreaking studies, there has been little empirical exploration into the structure of American police organizations. Traditional organizational inquiries have suggested that structural characteristics can be differentiated between those that represent complexity or differentiation within the organization and those that represent control mechanisms to coordinate and manage the complexity. This research investigates whether these various structural elements are indicative of two latent constructs by developing and testing measurement models representing structural complexity and control. Organizational scholars have also argued that structural complexity increases the demand for structural control. Maguire investigated this issue in the context of police organizations and found little support for the hypothesis. The paper reexamines this relationship by extending and replicating Maguire’s analysis to ascertain if a different specification and sample sustain his conclusion. Utilizing data from the 1997 Law Enforcement Management and Administrative Statistics survey and a survey conducted by Edward Maguire, the paper explores these issues using a sample of 401 large, municipal police organizations in the USA. The results indicate that structural control is unidimensional, while structural complexity is not. This study also provides modest evidence supporting an association between structural complexity and control.

According to community policing advocates, police agencies should implement a variety of important organizational changes. These changes are supposed to occur in a number of different substantive domains, including the culture, behavior, and structure of police organizations. This paper examines the evidence for change in just one of these domains: formal organizational structure. Based on concepts derived from organization theory, and using data from six different data sets, the paper explores whether the structures of US police organizations changed during the 1990s. Overall, it finds mixed evidence. Some changes have occurred in the direction encouraged by community policing reformers, some changes have occurred in the opposite direction, and some changes have not occurred at all.

This chapter will report on the issues that surround the coverage of police shootings in the United States. It will also look at the issue of race and policing. In particular, the events at Ferguson, St. Louis in August 2014 and other controversial incidents will be explored. The chapter will utilize theories of policing, employ a media analysis, and develop an issue history to explain the background to problems with policing in African-American neighborhoods over many decades, culminating in the rise of the Black Lives Matter movement.

A threatened sense of safety in public spaces is a problem for liveable communities. For better public policies, this study investigates multi-dimensional and multi-scalar aspects of gendered perceived safety and strategies by women and men in daily public spaces.

A face-to-face survey with 40 men and 50 women in a public space (Izmir, Turkey) is deployed. Descriptive statistics and regression analysis compare participants' perceptions of and strategies for safety across the city, neighbourhood and the study site.

Their experienced-based familiarities in public places increase women's perceived safety. As safety strategies, different place-based and gendered-preconditions appear for women and men going “outside” especially “alone” (i.e. unaccompanied). Reaffirming female vulnerability in public places, gendered preconditions include individuals' attributes. Of place-based preconditions, crowd and police are significant mechanisms for safety but emphasized differently by women and men. Housewives' female companionship in the study site develops a class- and gender-based claim for a safe place away from their underserved neighbourhood.

Gendered- and place preconditions for women's safety can inform design policies about surveillance and permeability of public spaces. Lack of data about class-based differences about perceived safety is a limitation.

Among a few, it takes perceived safety as performative acts with learned strategies across (rather than momentary perceptions in) socio-spatial spaces and provides a research framework that considers such acts with individual and spatial dimensions across multiple socio-spatial scales.

The purpose of this paper is to analyze the design and implementation of the police crackdown strategy employed in Mexico City and to discuss its limitations toward a medium-to-long-term reduction of crime rates for six types of robberies.

The present work employs generalized autoregressive conditional heteroscedasticity (GARCH) models to estimate the effect of police operations on the volatility of the rates of six types of robberies in Mexico City, as well as their persistence over time.

Results suggest that the concentration of policing in certain high-criminality spaces reduces crime rates in the immediate term; however, its permanence is contingent on policing design and behavioral characteristics of the targeted crime. Specifically, the Mexico City police crackdown strategy seems to be better suited for combating crimes of a “non-static” nature than those of a “static” nature.

Due to the nature of the data used for this research, the performed analysis does not enable a precise determination of whether the crime rates respond to temporal or spatial displacement.

Considering the obtained results, a re-design of Mexico City’s police crackdown strategy is suggested for the sustained reduction of the number of reported cases of robberies of a static nature.

Despite their importance, few studies have measured the impact of police crackdowns on city-level crime rates and whether their effect is temporary or permanent. The present study proposes the use of GARCH models in order to integrate the study of this phenomenon into criminal time series models.

This paper aims to present an application of location optimization techniques for deploying police facilities subject to budgetary and feasibility constraints. The objectives considered included minimizing the distances and maximizing the coverage of police stations over potential crime spots.

The optimization consists of two stages. In Stage 1, a minimum distance model is used to determine the locations of police stations. Given the locations of police stations, Stage 2 uses a maximum coverage model to determine the police patrol area. The framework is applied to a case in the Greater London Area. The authors also evaluate the resilience of the optimal solutions with the terrorist attack scenario on 7 July 2005 in Central London.

With the optimization models, it is shown that the average distance between police stations and potential crime spots is reduced by 19 per cent. The coverage percentage of potential crime spots is also increased from the existing 91.99 per cent to a nearly perfect 99.82 per cent. Nevertheless, the results reveal that the optimal police resources deployment is less resilient with respect to the existing one. The findings herein suggest the importance of incorporating measures of resilience into the optimization framework and the authors leave this topic for further investigation.

The study highlights the value of location optimization to police force deployment in terms of finding the optimal locations of police force with respect to the spatial distribution of crimes. In particular, the authors investigate its implication on urban resilience, which is among the first study of this kind.
