The DOJ used Palantir to build an app to help find criminals—and then shut it down

Recently uncovered documents show that the Department of Justice is no longer using a mobile app, built by Palantir, designed to help law enforcement officials search criminal records databases while operating in the field. Thousands of people, including agents at the U.S. Marshals Service, the Drug Enforcement Agency, and the Bureau of Alcohol, Tobacco, Firearms and Explosives, appear to have ended up using the app, which was called “SHIELD”.
