Strategy & Goals

The criminal legal system is decentralized; our approach embraces this, working locally first to make an immediate impact on transparency and access to data.

Our data is crowdsourced in collaboration with the community of people who need police data for their work.

Think Wikipedia meets Open Elections meets Internet Archive.

To see how we're progressing in more detail, check out our roadmap and long-term milestones.

Current focus

We're mapping Data Sources: which records are available? How are they accessed? How were they generated? How usable are they?

This work documents the current state of transparency in each jurisdiction, and lays the foundation for future work using this data.

Next up

We'll focus on helping people take ownership of their local Data Sources using our tools. People doing different kinds of work with the same data can share code, information, and computing power.

To get here, we'll need to build capacity with dedicated staff for community management and technical support.

Long term

PDAP becomes a trusted hub for directly accessing police data.

To get here, we'll need to be able to store large amounts of data responsibly. We'll need robust hosting infrastructure and operations support. In the meantime, we're learning about our users and how we can make the biggest impact.

Non-profit & community roles


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

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

Our paid staff are Josh Chamberlain and Jacob Quinn Sanders.

The PDAP community has pockets of volunteers, working together on their corner of the criminal legal system.

The people using police data have the agency to collect and share it with a community of fellow data nerds.

Funding & Support

The PDAP non-profit is funded by grants and individual contributions.

We are grateful for generous support from The Heinz Endowments.

The PDAP community is supported as a key program of the non-profit.

It uses the distributed computing power of its members to balance the workload and connect people with information using minimal resources.

Frequently Asked Questions

What kind of data do you collect?

Anything published by or about a criminal legal system agency: courts, jails, and law enforcement (police). You can read more about what a Data Source is in our docs.

Who is this data for?

The simple answer: everybody! Public records should be public.

Some real examples based on our hundreds of hours of research:

Why are you different from police watchdog groups?

We aren't a watchdog—our activism is data collection and accessibility, not analysis or reform. We aren't targeting "bad apples," we're documenting the police systems themselves.

Is this legal?

Yes. We're consolidating public information, in accordance with established legal precedents.

Are you affiliated with a political party?

No. Our only motivation is to provide better access to public records in an age of disinformation. Our members have diverse perspectives and goals for police institutions, but we are united by the common goal of transparency.

How do we know you work with good data and that we can trust you?

Every step in our process is accessible and transparent.

Where do you get your funding?

We're a 501c3 non-profit. We are accepting donations. The bulk of our 2022 funding comes from The Heinz Endowments.
