The integration of evidence-based policy into criminal justice reform – and into police reform specifically – is a daunting but necessary endeavor. In this essay, we examine police reform, including a review of the literature, which is summarized and guided by our experiences and thoughts into a broad conceptual framework for what we believe is needed to realize true change in the policing profession. This essay provides a brief review of the history of police reform and explores three primary reasons why it has failed so far: (1) the tendency to implement reactionary (i.e., knee-jerk) reforms; (2) the reliance on non-aspirational reforms; and (3) a lack of necessary evidence to guide reforms. We then provide what we believe to be the path forward – the co-ownership of evidence-based police reform by police executives and researchers. We encourage and advise police executives to be proactive, strategic, and courageous in owning reform, see greater value in being users and builders of evidence, and educate the public and their own officers. We also call on researchers to do better by creating the knowledge needed for the field and packaging it in a way that can be more easily consumed by practitioners, policymakers, and the community. We believe it is through this co-ownership that police reform efforts have the greatest potential for success.

将循证政策纳入刑事司法改革——尤其是警察改革——是一项艰巨但必要的努力。在这篇文章中，我们审视了警察改革，包括对文献的回顾，根据我们的经验和思想将其总结并引导到我们认为实现警务行业真正变革所需的广泛概念框架中。本文简要回顾了警察改革的历史，并探讨了迄今为止它失败的三个主要原因：（1）实施反动（即下意识）改革的倾向；(2) 依赖非预期的改革；(3) 缺乏指导改革的必要证据。然后，我们提供了我们认为是前进的道路——警察行政人员和研究人员共同拥有以证据为基础的警察改革。我们鼓励并建议警察行政人员积极主动、有战略眼光地进行改革，看到作为证据的使用者和建设者的更大价值，并教育公众和他们自己的官员。我们还呼吁研究人员通过创造该领域所需的知识并将其包装成一种更容易被从业者、政策制定者和社区使用的方式来做得更好。我们相信，正是通过这种共同所有制，警察改革努力才有最大的成功潜力。我们还呼吁研究人员通过创造该领域所需的知识并将其包装成一种更容易被从业者、政策制定者和社区使用的方式来做得更好。我们相信，正是通过这种共同所有制，警察改革努力才有最大的成功潜力。我们还呼吁研究人员通过创造该领域所需的知识并将其包装成一种更容易被从业者、政策制定者和社区使用的方式来做得更好。我们相信，正是通过这种共同所有制，警察改革努力才有最大的成功潜力。
