Criminal Justice Reform

We’re advancing long overdue reforms to reduce the harms of America’s broken criminal justice system.

In cities across America, communities face high rates of gun violence and significant harm caused by the criminal justice system, which disproportionately impacts people of color. For too long, the public sector has failed to address these overlapping and systemic crises, partly because policymakers view them as a trade-off. But to truly increase public safety, society must find solutions that advance justice and reduce gun violence simultaneously.

That’s why we’re working with public sector agencies to reform our criminal justice system by designing pretrial risk assessment tools, studying the effects of cash bail, and promoting treatment instead of incarceration for individuals arrested on non-violent substance use charges.

Our evaluation of the Narcotics Arrest Diversion Program found participants were 44% less likely to be re-arrested for drug possession and violent crime charges.

We worked with Luminosity and the NYC Criminal Justice Agency to design and implement New York City’s pre-trial risk assessment tool, helping low-risk defendants avoid jail time while they await trial and helping judges avoid releasing high-risk defendants.
