The Drug Enforcement Administration and the Bureau of Alcohol, Tobacco, Firearms and Explosives collaborated on plans to monitor gun show attendees using automatic license plate readers, according to a newly disclosed DEA email obtained by the ACLU through the Freedom of Information Act.

The April 2009 email states that “DEA Phoenix Division Office is working closely with ATF on attacking the guns going to [redacted] and the gun shows, to include programs/operation with LPRs at the gun shows.” The government redacted the rest of the email, but when we received this document we concluded that these agencies used license plate readers to collect information about law-abiding citizens attending gun shows. An automatic license plate reader cannot distinguish between people transporting illegal guns and those transporting legal guns, or no guns at all; it only documents the presence of any car driving to the event. Mere attendance at a gun show, it appeared, would have been enough to have one’s presence noted in a DEA database.

FK – Another reason to shut them down, as if we need another one.
