The ATF is under fire for botched storefront stings and other undercover operations across the country.

The Milwaukee Journal Sentinel reports that Inspector General Michael Horowitz opened an investigation into storefront stings in Milwaukee, Pensacola, St. Louis and Wichita, Kan.

The agency is already under investigation for its handling of a controversial drug-running probe, Operation Fast and Furious

Horowitz said the investigation will “examine possible systemic deficiencies in ATF’s storefront operations policies, and evaluate the effectiveness of the Monitored Case Program as an oversight tool in these operations.”

One of the problems with Operation Fast and Furious, he said, was the lack of oversight.
