Knowing More, but Accomplishing What? Developing Approaches to Measure the Effects of Information-Sharing on Criminal Justice Outcomes

RAND CorporationThis report from the RAND Corporation examines information-sharing tools from the Automated Regional Justice Information System (ARJIS) used by local, state, and federal public safety agencies in San Diego County. The report is aimed at criminal justice practitioners, policymakers, civil society organizations, and members of the public interested in information-sharing for criminal justice and public safety purposes. The study found that sharing information through ARIJS systems was associated with greater multi-agency involvement with specific people who commit crimes, which is consistent with the goal of reducing the effect of jurisdictional boundaries on agency activities and effectiveness. The paper concludes with suggestions for ways that new data systems could be better designed and existing systems could be improved to simplify analysis of shared data.
