The new acting director of the Bureau of Alcohol, Tobacco, Firearms and Explosives said Wednesday he was reassigning 11 of the agency's top officials in a bid to rebuild ATF after Operation Fast and Furious, in which agents let U.S.-purchased guns slip into the hands of Mexican drug cartels. ATF Acting Director B. Todd Jones said the reshuffling will help the agency focus on its "core missions of violent crime and public safety" and bring about "a certain level of accountability" in the wake of the controversy. "We're going to hit the reset button," said Jones,
