Council of State Governments (CSG) Justice Center - Justice Reinvestment
The Council of State Governments (CSG) Justice Center is working with a handful of states to implement justice reinvestment strategies. These states are designing policies to manage the growth of the corrections system, improve the accountability and integration of resources concentrated in particular communities, and reinvest a portion of the savings generated from these efforts to make communities receiving the majority of people released from prison safer, stronger, and healthier.

District of Columbia Crime Policy Institute

George Mason University (GMU), Department of Criminology, Law and Society - Center for Evidence-Based Crime Policy (CEBCP): The Evidence-Based Policing Matrix
The Evidence-Based Policing Matrix© is a research-to-practice translation tool that categories and visualizes all experimental and quasi-experimental research on police and crime reduction according to three common dimensions of crime prevention – the nature of the target, the extent to which the strategy is proactive or reactive, and the specificity or generality of the strategy. This categorization and visualization of policing evaluation studies reveals three-dimensional clusters of effective studies, which we refer to as "realms of effectiveness." These realms of effectiveness provide insights into the nature and commonalities of effective police strategies and can be used by police agencies to guide various aspects of their operations.
