Our police system is decentralized. In response, our approach is to build locally first. PDAP is developed in collaboration with the community of people who need police data for their work: activists, researchers, journalists, municipal employees, and individuals interested in understanding their local police system.

Combined, this work represents a national accounting of police transparency, policy, and accessibility.


We're building utilities and infrastructure to empower people who are interested in using police data.

Think Wikipedia meets Open States meets Internet Archive.


The PDAP non-profit builds a collection of open-source apps and services to help the community write scrapers and archive data.

PDAP is the steward for the archives. It ensures the data is verifiable and freely accessible.

PDAP sets a high standard for Scraper quality, and runs trainings to help the community meet it.

The PDAP community writes and maintains a vast library of Scrapers to cover every U.S. police agency.

The community is built on a mutual aid model, where the people using police data have the agency to collect and share it—as well as a community of fellow data nerds to help.


The PDAP non-profit has a traditional structure.

The PDAP board is Eddie Brown, Alec Akin, and Josh Lintag.

Our paid staff are Josh Chamberlain and Jacob Quinn Sanders.

The PDAP community is decentralized, with flat hierarchy and community governance.

Micro-communities of volunteers spring up around geographic regions or types of data, working together on their corner of the criminal justice world.
