Roughly 2 years ago I started building a database of fatal officer-involved shootings (OIS) at the agency-year level, going back in time as far as possible. If you’re not familiar with the OIS data landscape, here’s the gist:
Official data compiled by the FBI and NVSS have long been recognized as woefully incomplete and thus inadequate.
Unofficial data compiled by current/former journalists, activists, and researchers have become available over the last decade or so.
