Abstract Criminal justice cannot be highly effective or cost-efficient because of its fragmented design and the lack of research on systems operations and impacts. Substantial improvement to public safety and justice requires a systems approach that involves multiple stakeholder groups. This approach includes creation of an agency responsible for oversight, monitoring, and evaluation of criminal justice. It also includes reliance on systems analysis and evaluation research. The latter constitutes the easier task; the former requires political will and economic investment.

创建可以改善安全性和公正性的系统（以及零碎的更改为何行不通的原因）

摘要刑事司法由于其支离破碎的设计以及缺乏对系统运行和影响的研究，因此不能达到很高的效率或成本效益。要大幅改善公共安全和司法，就需要一种系统方法，涉及多个利益相关者群体。这种方法包括建立一个负责监督，监督和评估刑事司法的机构。它还包括对系统分析和评估研究的依赖。后者构成了较容易的任务。前者需要政治意愿和经济投资。
