The Council of State Governments Justice Center, a Rosenberg grant partner, has released an unprecedented study this week examining the extent that people on parole and probation contribute to overall crime rates.
Among the most notable findings of study, titled "The Impact of Probation and Parole Populations on Arrests in Four California Cities":
- The majority of all adult felony and misdemeanor arrests were of people who were not currently under supervision. People under supervision accounted for only 22 percent of total arrests.
- People under probation and parole supervision accounted for one out of every six arrests for violent crimes, and one out of every three drug arrests.
The Chiefs of the Los Angeles, Redlands, Sacramento, and San Francisco Police Departments commissioned the analysis in 2010. Collecting and analyzing the data required an extraordinary effort spanning 11 independent agencies, including four local police jurisdictions, county law enforcement and probation agencies, two county sheriffs departments and the California Department of Corrections and Rehabilitation (CDCR). Researchers at the CSG Justice Center collected and matched more than 2.5 million arrest, parole, and probation records generated between January 1, 2008 and June 11, 2011.
The study was funded by the Public Safety Performance Project of the Pew Center on the States, the Public Welfare Foundation, the Fund for Nonviolence, and the Rosenberg Foundation. To view the report, click here.
