The Citizens Police Data Project is a portrait of impunity backed by the police department's own data. We built CPDP so that data about police activity can be useful to the public.

The codebase for CPDP and all of the underlying datasets plus data processing scripts and FOIA responses are available publicly on GitHub.


Designed to serve as a national model for transparency, the Citizens Police Data Project is the product of a decade-long collaboration with the University of Chicago Law School’s Mandel Legal Aid Clinic.
