We need a unified archive of police data.

PDAP is consolidating data from every U.S. agency into a critical public resource.

To build one, we're using Python extractors written by activists to scrape public data from police websites.

We can't fix what we can't measure.

Every vision for the future of justice policy starts with the same first step: understanding the current system.

We can use already public data to understand the police systems around us.

Data Collection

There are over 18,000 police organizations, each with a unique way to publish information. There is no single source to access this public data. We can make it usable, measurable, and actionable by putting it in one place.
