Reforms Without Results: Why states should stop excluding violent offenses from criminal justice reforms

reforms without results report thumbnail

Too many states are passing criminal justice reforms that ignore the majority of people in prison: people convicted of violent crimes. In Reforms Without Results, we explain why people convicted of violence must be allowed to benefit from laws that expand early release, create alternatives to incarceration, and ease the reentry process. Our report includes a concise, rigorous overview of the existing research on violent crime, as well as an interactive U.S. map showing which states have passed laws that exclude people convicted of violence.
