Transparency into prosecutorial decision-making is critical to ensuring that a prosecutor's office is accountable to the people it serves. For example, prosecutors can use data to assess whether current policies are being applied consistently, ensure that resources are appropriately focused for fair and equitable outcomes, and develop new policies that can address community concerns, such as racial disparities in the criminal legal system. Moreover, by making their data publicly available, prosecutors can empower the public to assess information about how cases are being processed within their communities and to better understand the role of the prosecutor in the criminal legal system.
The Cook County State's Attorney's Office (SAO), one of the nation's largest prosecutor's offices, recently released data on the handling of felony cases from 2011 to present. Using the Cook County felony case data, the Data Collaborative for Justice (DCJ), a non-profit criminal justice research organization, developed a data visualization that enables the public to analyze how cases prosecuted by the SAO move through the criminal legal system.
DCJ's Felony Case Processing Data Visualization Tool (see "Explore the Data" above) allows users to view outcomes at three key stages of the felony cases process:

DCJ is grateful for the assistance of the Cook County SAO in responding to DCJ's questions and inquiries during the development of the Felony Case Processing Data Visualization Tool. DCJ is particularly appreciative of the assistance provided by Matthew Saniie, SAO's Chief Data Officer, and Lisa Li, SAO Data Integration Analyst.
