“Today, Sunlight is launching Hall of Justice, a robust, searchable data inventory of nearly 10,000 datasets and research documents from across all 50 states, the District of Columbia and the federal government. Hall of Justice is the culmination of 18 months of work gathering data and refining technology. The process was no easy task: Building Hall of Justice required manual entry of publicly available data sources from a multitude of locations across the country. Sunlight’s team went from state to state, meeting and calling local officials to inquire about and find data related to criminal justice. Some states like California have created a data portal dedicated to making criminal justice data easily accessible to the public; others had their data buried within hard to find websites. We also found data collected by state departments of justice, police forces, court systems, universities and everything in between. “Data is shaping the future of how we address some of our most pressing problems,” said John Wonderlich, executive director of the Sunlight Foundation. “This new resource is an experiment in how a robust snapshot of data can inform policy and research decisions.”
