The purpose of the study is to examine gun violence prevention practices among urban police in the USA, assessing their scope, effectiveness, limitations, and impacts.

A national survey was conducted with police agencies serving cities of 100,000 or more people.

Strategies used most frequently and rated as most effective include targeted efforts focussed on high‐risk places and groups, as well as multi‐agency problem‐solving efforts, particularly those involving federal authorities. However, most agencies make limited use of proactive strategies to reduce gun crime, and there are substantial gaps in the enforcement of many gun laws. Results also suggest that gun crime is lower in places where police engage in more intensive gun‐related enforcement and prevention efforts.

The survey focussed only on large US cities. Implementation of the strategies could not be examined in detail, and assessments of the effectiveness of strategies reflect the views of practitioners. There is a need for more in‐depth research on gun‐related enforcement and prevention practices, their effectiveness, and the organizational and environmental factors that facilitate or hinder them.

The study highlights strategies that should be given priority consideration in policy decisions. The findings also suggest that police efforts to address gun crime can be enhanced considerably – and that doing so may produce demonstrable reductions in gun crime. Further examination of policy changes necessary to facilitate these efforts is warranted.

This study represents the first national survey of gun violence reduction efforts by police in the USA.

Because that the crime in a wide way impacts the life of the people in the big metropolis, researchers have treated the question from several angles. The purpose of the paper, under the umbrella of operational research, is to develop a model of the ordering of police strategies, in the fight against crime in general, according to a certain criminal demand.

For the construction of the impact matrix of the strategies under the reduction of crime rates, considering a portfolio of crimes, a questionnaire applied to specialists was used. In a second moment, defined the criteria and strategies to be ordered, the multicriteria ELECTRE IV method was used, which with the help of the J-Electre software emulated the systematized data in the impact matrix and produced the final ordering of the most efficient strategies, in the fight against crime, in the perception of decision-makers.

As a result, the research revealed that policing strategies directed at solving specific crimes are the most effective in the perception of decision-makers after the emulation of data with the ELECTRE IV method.

As research implications, it can be inferred that the use of multicriteria methods in the modeling of problems in the area of public security can contribute to rationalization of the use of the means available in the fight against crime in large cities. The research showed that it is possible to use customized policing strategies to a certain reality.

The method presented in this research is directly related to the major strategies: problem-oriented policing and hot spot policing. This method allows public safety managers to consider the possibility of combining different law enforcement strategies in each context. In this sense, the use of the multiple-criteria decision analysis (MCDA) (ELECTRE IV) method allows the evaluation of a large set of alternatives according to a set of established criteria, speeding up the process and reducing subjectivity, allowing the manager to analyze several scenarios with greater clarity and impartiality and choosing an alternative that best solves the proposed problem. The expected result is the rationalization of the available means applied in the search for the reduction of crime rates.

The customization of policing strategies, according to criminal demands, implies the efficient way to reduce criminal charges. Reducing criminal rates enables the development of the local economy, tourism and the quality of life of people by exercising their freedom to the full.

The originality lies in filling a gap in the literature with the elaboration of the impact matrix of policing strategies in reducing criminal indices, and in their associated use in ordering strategies through a multicriteria method.

The purpose of this case study was to investigate the learning strategies of police officers. Participants were 80 police officers serving in a Midwestern police agency. Of these, 49 were assigned to patrol duties and 31 were assigned to community oriented policing duties. Each participant completed the “Assessing the Learning Strategies of Adults” (ATLAS) instrument. When individual variables were examined in describing learning strategies among police officers, no significant differences were found using both chi‐square and a one‐way ANOVA. A multivariate discriminant analysis produced a recognizable discriminant function, and three variables met the criteria to be included in the interpretation of the meaning of the discriminant function. Predominately, male police officers prescribed to the learning strategy traits that are desired in community oriented policing. Police officers who ascribed to the learning strategies which are more congruent with traditional policing were slightly younger than the officers who ascribed to the learning strategy appropriate for community policing. Furthermore, more females in this study ascribed to learning strategies more related to traditional policing.

The purpose of this paper is to develop a method for the discovery of knowledge in emergency response databases based on police incident reports, generating information that identifies local criminal demands that allow the selection of the appropriate policing strategies portfolio to solve the problem.

The developed model uses a methodology for the discovery of knowledge involving text mining techniques using Latent Dirichlet Allocation (LDA) integrated with the ELECTRE I multicriteria method.

The developed method allowed the identification of the most common criminal demands that occurred from January 1 to December 31, 2016, in the policing areas studied. One of the crimes does not occur homogeneously in a particular locality. In this study, it was initially observed that 40 per cent of the crimes identified in the Integrated Public Safety Area 5, or AISP-5, (historical city center of RJ) had no correlation with AISP-19 (Copacabana - RJ), and 33 per cent of crimes crimes in AISP-19 were not identified in AISP-5. This finding guided the second part of the method that sought to identify which portfolio of policing strategies would be most appropriate for the identified demands. In this sense, using the ELECTRE I method, eight different scenarios were constructed where it can be identified that for each specific criminal demand set there is a set of policing strategies to be applied.

The collected data represent the social dynamics of neighbourhoods in the central and southern zones of the city of Rio de Janeiro during the specific period from January 2013 to December 2016. This limitation implies that the results cannot be generalised to areas with different characteristics.

The developed methodology contributes in a complementary way to the identification of criminal practices and their characteristics based on reports of police occurrences stored in emergency response databases. The knowledge generated through the identification of criminal demands allows law enforcement decision makers to evaluate and choose among the available policing strategies, which best suit the reality they study, and produce the reduction of criminal indices.

It is possible to infer that by choosing appropriate strategies to combat local crime, the proposed model will increase the population’s sense of safety through an effective reduction in crime.

The originality of the study lies in the integration of text mining techniques, LDA and the ELECTRE I method for detecting crime in a given location based on crime reports stored in emergency response databases, enabling identification and choice, from customized policing strategies to particular criminal demands.

Although community policing is still in its formative stages in the USA, much of the research has been directed to programmes being implemented in large cities where high levels of crime and fear are part of the social fabric. Research on community policing in small cities and towns is still in the preliminary stage. To meet this challenge, the present paper reviews data from a survey of 82 police departments in cities and towns having less than 200,000 inhabitants. Emphasis is directed to the kinds of community policing strategies employed by the departments and the opportunities for community residents to participate in the decision‐making processes relating to community policing. Data reveal that the transition of police departments from a traditional reactive philosophy to one of community policing is an evolving process. Structured strategies that provide resident input into community policing are likely to occur as the programmes evolve over time, and generally follow changes in police deployment and the establishment of working relation‐ships with community agencies, both public and private.

The purpose of this study is modelling of a problem of policing strategy order using a multicriteria method.

For the construction of the impact matrix strategies under the reduction of crime rates, considering a portfolio of crimes, a questionnaire applied to specialists was used. In a second moment, defined the criteria and strategies to be ordered, the multicriteria PROMETHEE II method was used, which with the help of the Visual PROMETHEE software, emulated the systematised data in the impact matrix and produced the final ordering of the most efficient strategies, in the fight against crime, in the perception of decision makers.

As a result, this research revealed that radio patrol, when used in a non-randomised manner, is the most effective policing strategy in reducing the 18 criminal demands studied in the perception of decision makers after data emulation with the PROMETHEE II method.

As research implications, it can be inferred that the use of multicriteria methods in the modelling of problems in public security area can contribute to the rationalisation of use of the available means in the fight against crime in large cities. This research showed that it is possible to use customised policing strategies to absolute reality.

The practical impact of this research lies in optimising the resources available to law enforcement agencies in the fight against crime in general.

It can be inferred that by choosing appropriate strategies to combat local crime, there is a direct implication in optimising the resources that the government makes available to police agencies. This optimisation allows pressure reduction under the public budget for more features. The model for choosing more effective strategies contributes to local crimes decrease, increasing the sense of the population security.

The originality lies in filling a gap in the literature with the elaboration of the impact matrix of policing strategies in reducing criminal indices and in their associated use in ordering strategies through a multicriteria method. This study contributed to applied police intelligence.

Purpose – This chapter uses preventive and responsive policing strategies in tandem to develop a multi-level theory that explains the relationship between the police and violence.

Design/methodology/approach – The chapter brings together classical scholarship and more recent sociological research to demonstrate that an effective response to violence is critical in upholding the state’s monopoly on violence and that police officers can reduce violence by preventing it and responding to it.

Findings – Theoretical and practical evidence support the balanced use of responsive and preventive policing strategies to reduce violence. Findings from the literature are used to argue that (1) when law enforcement officers do not effectively respond to violence and/or crime prevention strategies are nonexistent in a community, neighborhood crime is increased and (2) when citizens do not perceive law enforcement officers as legitimate and effective agents of authority, they become more likely to engage in violent offending (Tonry, 1995; Tyler, 2006).

Originality/value – Research has supported the effectiveness of “proactive” (Braga, Papachristos, & Hureau, 2014; Weisburd & Telep, 2014) and “reactive” (Nagin, 2013; Paternoster, 2010) policing strategies in reducing violence, but no research has combined strategies of prevention and response to explain the relationship between the police and violence. The theory proposed in this chapter demonstrates the utility of explaining the instrumental and legitimacy functions of the police across various levels and brings under-protection to the forefront of research on policing and violence.

This paper aims to explore police perspectives on community engagement strategies within the context of crime prevention in South Africa, focusing on Johannesburg metropolitan police stations. The study’s objective is to scrutinise the effectiveness and challenges of community policing strategies.

Through a qualitative research approach, this study conducted unstructured interviews with station commanders and visible policing officers across 10 Johannesburg metropolitan police stations.

The findings reveal that community policing strategies, such as community–policing forums, sector policing, street patrollers and social media utilisation, can effectively engage communities as partners in crime prevention. However, certain challenges such as resource limitations and difficulties in policing-specific regions, were also identified.

This study contributes to the broader understanding of community–policing partnerships and the practical implications of community–policing strategies in South Africa, suggesting areas for improvement and adaptation to the unique South African context. This knowledge can help optimise efforts to foster stronger relationships between police and communities, bolster public trust and ultimately improve crime prevention outcomes.

This paper is designed to critically review and analyze the body of research on a popular gang reduction strategy, implemented widely in the United States and a number of other countries, to: (1) assess whether researchers designed their evaluations to align with the theorized causal mechanisms that bring about reductions in violence; and (2) discuss how evidence on gang programs is generated and consumed. That review and assessment is then used to frame a research agenda for studying gang interventions.

A case study design is used to generate a multi-faceted understanding of the possible avenues for evaluation research on the law enforcement-based strategy known as the Group Violence Intervention. The paper discusses questions that remain to be answered about the strategy, such as “what type of deterrence is operating?” and if the model actually works by the threat of deterrence, and not by removing high-risk offenders and shootings from the street, what activities are needed to maintain the effect?

Across roughly two dozen impact evaluations of GVI, none have examined the likely cause and effect components of this multi-partner strategy in reducing the violence. Furthermore, there are many issues related to the production and generation of criminal justice evaluation research that have adversely pushed the balance of evidence on what works in gang reduction toward law enforcement programming. However, there are many strategies that researchers can use to think broadly about appropriate and holistic research and evaluation on gangs and gang programming.

The recommendations for research, if implemented, can help build a body of knowledge to move toward community-based and restorative models of gang violence reduction.

This original piece is one of the first essays to contextualize and discuss how aspects of the production of social science research on gangs may directly impact what programs and strategies are implemented on the ground.

Scholarship on the effects of various kinds of state repression (e.g., counterterrorism, counterinsurgency, protest policing) on subsequent dissent has produced a body of contradictory findings. In an attempt to better understand the effects of one form of state repression – protest policing – on one form of dissent – public protest – this paper examines the effects of various policing strategies used at protest events on subsequent protest levels in the United States between 1960 and 1990. Theoretically, we argue the effects of repression cannot be broadly theorized but instead need to be hypothesized at the level of particular police strategies and actions. We theorize and empirically examine the impacts of five police strategies, while also improving on prior analyses by producing a comprehensive model that examines lagged and nonlinear effects and examines the effects across the entire social movement sector, as well as across two specific movement industries. Results (1) confirm that not all police strategies have the same effects; (2) show that policing strategies tend to have predominately linear effects; (3) show that police actions have their strongest effects in the very short term, with few effects detectable after a few weeks; and (4) point to interesting differences in the effects of policing strategies on subsequent protest across different social movements.
