The FBI steadily, stealthily compiled a massive facial recognition database without oversight and in disregard of federal law, according to a report released today by the Government Accountability Office.

The bombshell report reveals that the FBI dipped into driver’s license photo databases from 16 states, as well as passport and visa photo databases from the State Department, feeding its facial recognition with millions of photos of Americans and foreigners who have never been accused of a crime. The FBI has access to a whopping 411.9 million images for use in facial recognition, roughly 30 million of which are mug shots.
