Changing environments demand that police improve their effectiveness in reducing crime, while maintaining community confidence, support and legitimacy. How can police agencies encourage third parties to take responsibility for crime problems while avoiding inequitable outcomes?

The evidence for effective policing for crime reduction is examined, with a focus on third party policing. Potential adverse outcomes are discussed, and a normative framework is proposed.

Third party policing that is both effective and legitimacy enhancing is possible, if four key principles are observed. These are conducting a broad planning approach that includes consideration of the detriments as well as the benefits of strategies especially to vulnerable community members, clearly identified goals and the use of the least coercive means possible, clearly articulated policies and protocols, and institutional and individual accountability for strategy implementation and outcomes.

There is emerging evidence about the effectiveness of regulatory approaches to crime reduction, such as third party policing, but little attention has been paid to its potential for inequitable outcomes and impact on police legitimacy.

This paper aims to present the evaluation results of a practice‐based research partnership to develop and implement a new police organizational model for crime reduction into one police agency which was implemented based on the best practices of problem‐oriented policing, hot spots policing, and Compstat.

A qualitative process evaluation of organizational changes and an impact evaluation examining specific crime types was conducted over seven years to determine increased efficiency, collaboration, and effectiveness of the police department's crime reduction strategies.

The process evaluation found that the agency improved its crime analysis capabilities as well as its coordination and communication, expanded its problem solving activities, and made a significant cultural shift towards incorporating problem solving and accountability throughout the organization. The impact evaluation found that the crimes addressed in the implementation – theft from vehicle – did decrease overall and when compared to other crime types and to neighboring jurisdictions.

The limitations of the research are that these results are from one agency and that the impact evaluation is not conclusive.

The work was carried out over seven years in which the collaboration between the researcher and the agency was seminal. The model developed can be used by other police departments, and a key finding was that strong leadership played the most important role in the implementation of the crime reduction strategies and accountability practices.

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.

This study examines the effect of TimeZup – a lever pulling strategy designed to reduce gun violence in New Haven, Connecticut.

A series of ARIMA and dynamically complete models are estimated to determine if TimeZup was associated with any significant changes in New Haven's murder, firearm robbery and firearm assault rates. A quasi-experimental design is also used to compare New Haven to six, similarly situated cities in the Northeastern United States.

The results indicate that New Haven experienced a significant decrease in its firearm robbery rate in the summer of 1997 – a date that preceded TimeZup but coincided with other lever pulling strategies implemented by the New Haven Police Department.

Although an older program, TimeZup was not rigorously analyzed. After the conclusion of the program, basic pre- and post-comparisons suggested TimeZup was effective. Using a rigorous methodology, this study shows it was not. This study points out that interventions such as TimeZup often coincide with pre-existing crime reduction strategies. Evaluators should account for those pre-existing strategies because it may be those strategies – and not the intervention being examined – that are impacting crime rates.

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.

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.

The purpose of this paper is to explore the role of leadership in problem‐oriented policing (POP).

This paper uses interrupted time series models to isolate the impact on crime trends of a transformational leader's efforts to spearhead the implementation of a program of POP, called the problem solving model (PSM), in a southern state in Australia.

This paper finds that the PSM led directly to an impact on overall crime, with a significant reduction in crimes per 100,000 persons per year after the introduction of the PSM. The majority of the overall crime drop attributable to implementation of POP was driven by reductions in property crime. It was noted that the leadership influence of the PSM was not effective in reducing all types of crime. Crimes against the person where not affected by the introduction of the PSM and public nuisance crimes largely followed the forecasted, upward trajectory.

The driver behind the PSM was Commissioner Hyde and the success of the PSM is largely attributable to his strong commitment to transformational leadership and a top‐down approach to implementation. These qualities encapsulate the original ideas behind POP that Goldstein (1979, 2003), back in 1979, highlighted as critical for the success of future POP programs.

Reducing crime is an important part of creating safe communities and improving quality of life for all citizens. This research shows that successful implementation of the PSM within South Australia under the strong leadership of Commissioner Hyde was a major factor in reducing property crime and overall crime rates.

This paper is valuable because it demonstrates the link between strong leadership in policing, the commissioner's vision for POP and how his vision then translated into widespread adoption of POP. The study empirically shows that the statewide adoption of POP led to significant reductions in crime, particularly property crime.

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.
