In post-Ferguson America, police departments are being challenged to implement evidence-based changes in policies and training to reduce fatal police-citizen encounters. Of the litany of recommendations believed to reduce police shootings, five have garnered widespread support: body-worn cameras, de-escalation training, implicit bias training, early intervention systems, and civilian oversight. These highly endorsed interventions, however, are not supported by a strong body of empirical evidence that demonstrates their effectiveness. guided by the available research on evidence-based policing and informed by the firsthand experience of one of the authors in implementing departmental reforms that followed the fatal shooting of a civilian by an officer, this article highlights promising reform strategies and opportunities to build the evidence base for effective use-of-force reforms. We call upon police executives to engage in evidence-based policing by scientifically testing interventions, and we call on academics to engage in rapid research responses for critical issues in policing.

In many disciplines, there is a wealth of primary evaluation research on what works, and systematic reviews that synthesize that evidence. This is, of course, extremely positive. However, the sheer scale of the information and the way in which it is indexed and presented can mean that it is difficult for practitioners to locate the best available evidence. For this reason, in health, education, and other disciplines, using techniques from information science, researchers have systematically assembled databases such as those hosted on healthevidence.org and educationendowmentfoundation.org which bring together the most reliable evidence. Hitherto, no such database has existed for crime and criminal justice interventions. This article sets out some of the challenges and early findings of one exercise which aims to produce such a database, being completed as part of the What Works Centre for Crime Reduction initiative in collaboration with the College of Policing.

Scholars and practitioners who develop evidence-based crime policy debate on how best to translate criminological knowledge into better criminal justice practices. These debates highlight the counterpoised problems of over-selling the contribution of scientific evidence; or, alternately, overemphasizing the limitations of science. This challenge attends any attempt to translate research findings into practice; however, and problematically, in criminology this challenge is rarely approached in a theoretically coherent fashion. This article therefore seeks to theorize uncertainty in criminology by examining insights on communicating scientific uncertainty in other fields, and applying these insights specifically to the field of Evidence-Based Policing (EBP). Taking the position that all science is inherently uncertain, we examine the following four aspects of the field: the particular uncertainties of criminology, variance in receptivity to research, the lack of evidence regarding effective communication, and the boundaries of evidence. Building on this analysis, we set out the normative challenge of how researchers should characterize and balance the implications and limits of scientific findings in the decision-making process. Looking ahead, we argue for the need to invest in an empirical project for determining meaningful strategies to express research evidence to decision-makers.

Using a multi-method approach in four large law enforcement agencies, both urban and suburban, this study examined many of the social, organizational, and behavioral aspects of implementing police technologies, so as to make recommendations for optimizing the use of technology in policing.

The study consisted of officer surveys, field observations, interviews, focus groups, and experimental and quasi-experimental evaluations. It assessed the uses and impacts of several information, analytical, surveillance, and forensic technologies, including information technology (IT), mobile computing, crime analysis, and license plate readers. The study determined how these technologies affected policing operations, management, agency structure, culture, efficiency, effectiveness, citizen interaction, and job satisfaction. Overall, the study found that technology’s effects on policing are complex and often contradictory.

The recommendations for police agencies include a broad base of participation in the planning and implementation process for a new technology, involving those who will be affected by the technology; providing pilot testing and refinement of early versions of a technology; ensuring appropriate training in the characteristics and uses of the technology; and having a systematic and continuous follow-up, in-service training, ongoing technical support, and adaptation to lessons learned.

FROM THE PREFACE: “The movement for evidence-based policing in the 1990s came on the heels of the concept of evidence-based medicine in the same decade, but with far less clinical research to apply in policing practices. Since then, police research findings have been growing at a rapid rate and have been reviewed by the National Academies of Sciences, Engineering, and Medicine on repeated occasions in the last two decades. However, scant research findings have been reported at the country level, examining differences in police systems and policies across nations. In an era when the U.S. Congress has mandated better evidence to support public expenditure, the application of that mandate to overseas police development requires two responses. One is to do the best translation possible from existing research comparing differences between and within countries. The other is to map out research and action agendas that will promote the growth of new evidence to provide better guidance to policing in the international context.”

This Emerging Evidence Report describes the availability of evidence on modern slavery interventions in Myanmar presented in the programme's interactive Evidence Map. This report on Myanmar uses the same methodology and complements the evidence map on interventions to tackle trafficking, child and forced labour in South Asia for Nepal, India, Pakistan, and Bangladesh. The Evidence Map provides an outline of where evidence is concentrated and where it is missing by mapping out existing and ongoing impact evaluations and observational studies exploring different types of modern slavery interventions and outcomes for specific target populations (survivors, employers, landlords, service providers, criminal justice officials) and at different levels (individual, community, state). It also identifies key ‘gaps’ in evidence. Both the Evidence Map and this report foremost target the UK Foreign, Commonwealth & Development Office (FCDO) and its partners in the CLARISSA research programme to support evidence-informed policymaking on innovations to reduce the worst forms of child labour. We hope that it is also useful to academics and practitioner
