How do we work?

We're a rotating cast of volunteers with a flat organizational structure. The core PDAP staff keep the lights on and allow our community to move the mission forward, step by step.

Get involved

We're a learning organization, and we want to hear from you. If you have questions, concerns, suggestions, or expertise, reach out in Discord or to [email protected].

Non-code volunteering

  • Anyone with basic computer skills can help build our database of Data Sources.
  • People with any level of criminal justice related experience can give feedback and serve as a sounding board in Discord.
  • Anyone with a network of trusted friends and collaborators can text, email, or DM our website to a friend who might be able to contribute.

Code volunteering

  • We welcome help from coders of any experience level to write data scrapers. Python is our preferred language; ultimately, use what makes you happy.

Use our Data

If you have a question you'd like to answer about the police, reach out to [email protected] or in Discord. Our community of experts of volunteers may be able to help you. We're in the early days, and don't have much published yet—your project could be one of our first case studies.
