In response to a 404 Media investigation, Sen. Ron Wyden is demanding more information about how a federal license plate reader camera program works. Last month, we reported on the High Intensity Drug Trafficking Area program’s license plate reader database , which mirrors data from city license plate reader programs onto federal databases. The HIDTA program falls under the White House’s Office of National Drug Control Policy, which infamously ran a secretive cell phone data surveillance project called Hemisphere. We reported that HIDTA has now created a complex system for the federal government to obtain license plate data from companies like Flock, Axon, and Motorola via a series of agreements with cities and towns across the country. In a letter to Sara Carter, director of the Office of National Drug Control Policy, Wyden said that the office needs to publish a report it commissioned into the privacy practices of several of its surveillance programs, including the license plate reader database
