Prison, Police, and Programs: Evidence-Based Options that Reduce Crime and Save Money

Source: Steve Aos, Elizabeth Drake, Washington State Institute for Public Policy, November 2013

From the abstract:
…This report updates and extends WSIPP’s list of well-researched policies that reduce crime. We display our current tabulation of evidence-based prevention, juvenile justice, and adult corrections programs, and we include our initial reviews of prison sentencing and policing.

As with our previous lists, we find that a number of public policies can reduce crime and are likely to have benefits that exceed costs. We also find credible evidence that some policies do not reduce crime and are likely to have costs that exceed benefits. The legislature has previously used this type of information to craft policy and budget bills. This updated list is designed to help with subsequent budgets and policy legislation.
