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

# The DOJ Built a Facial Recognition App to Catch Criminals—Then Shut It Down The Department of Justice teamed up with data company Palantir to create a mobile app called SHIELD that helped law enforcement officers search criminal databases and identify suspects using photos of driver's licenses. Thousands of federal agents at agencies like the FBI and DEA used the tool starting around 2019, but the DOJ quietly discontinued it by early 2023. The story highlights how even when the government invests in new surveillance technology, these systems don't always last once they're up and running.
