This brief takes the reader through a 10-year journey of seeking to embed Evidence Based Policing within one of the largest police forces in the world - the Metropolitan Police Service in London, England - from the inside. As a topic, Evidence Based Policing has generated considerable recent interest and academic discussion - although largely remains without a consistent guiding voice for police practitioners. The aim of the brief is to expand upon the current discussions and address this gap within the day-to-day reality of policing where translation of research is a routine part of the day job. The book is organised into three sections: the first explores receptivity to evidence, asking practitioners to locate where they are on a continuum of evidence based craftwork; the second presents the importance of programme integrity and effective implementation in police craft; and the final section explores the challenges in professionalising policing and offers a more nuanced discussion around what it really means to be evidenced based. Throughout the brief the authors promote an insider whole-force strategic approach in landing evidence into policing 'business as normal' as opposed to an external academic or educated individual officer translation approach. Over the course of the monograph the authors draw upon their decade of experience providing case studies, toolkits, exercises, anecdotes and research experience as an inspiration for police practitioners both to practically support and inspire better evidence based working as part of the day job.
