The Police Data Accessibility Project, which started on Reddit, aims to aggregate all public police records into one easily searchable, open source database
The Police Data Accessibility Project aims to request, download, clean, and standardize public records that right now are overly difficult to find.
Context & Ripple Effects
Access to US police data is fragmenting in two directions at once. On one side, activists are dumping it wholesale — DDoSecrets published nearly 270 GB of raw departmental data two weeks before this story. On the other, official channels are closing: Chicago PD pulled the arrest API that journalists relied on after it was used to check the department's looting claims (the arrest API shutdown). The Police Data Accessibility Project is the third path — slow, lawful, volunteer-driven public records work, born on Reddit, aimed at making the data systematically available instead of leaked or locked up.
The project also answers a problem its own coverage keeps surfacing: even when records exist, they are unusable at scale. Ars Technica's 4.6M-scan license plate request took a single newsroom months of effort for one dataset, and Benchmark Analytics' attempt to flag problem officers is stymied by inconsistent departmental data. State-level precedents like California DOJ's OpenJustice show comparison across agencies is possible — but only where a government builds it. PDAP is betting volunteers can build the national version.
First-order effects
- Journalists and researchers gain a single searchable index of police records, replacing the current model of filing separate requests to each department — the labor that produced one-off stories like Ars Technica's license plate database.
- Police departments face a coordinated, persistent requester rather than episodic individual ones, raising the effective cost of withholding or slow-walking public records.
Second-order effects
- As official feeds close — Chicago PD's API shutdown being the template — demand migrates to independent aggregators like PDAP, making volunteer-built databases de facto infrastructure for accountability reporting.
- Commercial players like Benchmark Analytics, whose analytics are bottlenecked by messy inputs, gain from any standardized corpus while competing with free open alternatives for the same underlying data.
Third-order effects
- If the pattern holds, police transparency splits into a two-tier system: government-built portals like OpenJustice where states cooperate, and grassroots open-source archives everywhere else — with the latter setting the standard journalists actually use.
- Departments that withdraw official access increasingly push scrutiny toward leak-based releases like DDoSecrets', which carry far less quality control and more legal risk — an argument for building the legitimate channel before it's forced.
The trend: US police accountability data is shifting from ad-hoc records requests and activist dumps toward standing, standardized open-source aggregation built outside government.
