The Bureau of Alcohol, Tobacco, Firearms, and Explosives, or ATF, has a long history of excess and overreaching … and they’re at it again.

Using exaggerated reports of gun smuggling from the U.S. into Mexico as their justification, the agency has filed for an emergency regulation requiring gun dealers to keep track of their customers and file special reports to ATF whenever a customer purchases more than one semi-automatic rifle within any 5-day period.

Such special reporting is already required for multiple sales of handguns and has proven to be thoroughly useless as a law enforcement tool.
