"Nationally, it's been some of the more conservative voices that have been aggressive in calling for criminal justice reform, and part of that driving force is the fiscal cost of tough-on-crime policies that lead to over-incarceration," Raoul said. "Nobody is saying you let predators out, the people who do god-awful things need to go to prison, but we have to be measured about our criminal justice policies in a way that maintains public safety but doesn't waste money because politicians want to characterize themselves as tough on crime."
