Efforts to implement the Justice Reinvestment Initiative (JRI) — a data-driven model for improving public safety by identifying and implementing evidence-based reforms that address drivers of excessive and repeated incarceration and reinvest cost savings in effective strategies — have generally paid off, an evaluation by the Urban Institute finds. The report, Local Justice Reinvestment: Strategies, Outcomes, and Keys to Success (24 pages, PDF), found that the seventeen local jurisdiction that have implemented JRI over the last six years have committed to a number of reforms, including improving their data capacity, finding better ways to address the needs of frequent "front-end users" of the correctional system, reforming pretrial processes by assessing defendant's risk factors, and implementing evidence-based community supervision provision. The report also found, however, that JRI has not uniformly generated savings that can be easily quantified and directly reinvested in other public functions.
