The evidence-based policing (EBP) movement has intensified in many countries around the world in recent years, resulting in a proliferation of policies and infrastructure to support such a transformation. This movement has come to be associated with particular methods of evaluation and systematic review, which have been drawn from what is assumed to prevail in medicine.Given the credibility EBP is currently enjoying with both practitioners and government, it is timely to subject its underpinning logic to thoughtful scrutiny. This involves deliberating upon the meaning of evidence and what different models of knowledge accumulation and research methods have to offer in realising the aims of EBP. The communication and presentation of evidence to practitioner audiences is another important aspect of EBP, as are collaborative efforts to 'co-produce' new knowledge on police practice.This is the first book that takes a kaleidoscopic approach to depict what EBP presently is and how it could develop. The chapters individually and collectively challenge the underlying logic to the mainstream EBP position, and the book concludes with an agenda for a more inclusive conceptualisation of evidence and EBP for the future. It is aimed at students and academics who are interested in being part of this movement, as well as policymakers and practitioners interested in integrating EBP principles into their practices.
