Police accountability
Seven analyses, two baselines:
the people, and the crime they report
Every figure is computed live from MPD records when the page loads, with the methodology and every caveat beside it. Some analyses point to disparity and some favor MPD; all are published at the same prominence, because the method reports whatever the data says.
Stops by district. How the racial makeup of MPD stops compares with
each district's own population, for all seven districts.
The trend. The same measure, year by year, from 2019 through 2025,
citywide and per district.
Searches: the outcome test. Search and frisk rates by race, and how
often those searches actually find something.
Arrests. Thirteen years of adult arrest records, measured against
district populations.
Enforcement vs reported crime. Stop, frisk, and arrest volume measured
against the victim-initiated crime residents report, under two denominators.
Camera vs officer enforcement. Where officer-written traffic tickets
land, compared with where automated cameras record violations.
The veil-of-darkness test. A causal test of whether daylight, when
race is visible before a stop, changes who gets stopped.

Our mission
Police data for the public
Justice Lens measures how policing actually lands across DC: who gets stopped, searched, ticketed, and arrested, weighed against who lives in each neighborhood.
Every analysis carries its method and its caveats, and publishes whatever the data says, so communities, journalists, and researchers can ask harder questions with numbers that hold up.
