The Citizens Police Data Project (CPDP.co) is a tool for holding police accountable to the public they serve.

CPDP takes records of police interactions with the public that would otherwise be buried in internal databases and opens them up to make the data useful to the public, creating a permanent record for every police officer and a public record for every civilian complaint. 
 

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.
