“Our investigation made clear that the failures within ATF, which included a long term strategy in Operation Fast and Furious that was fully supported by the U.S. Attorney’s Office, were systemic and not due to the acts of only a few individuals,” (.pdf) wrote Inspector General Michael Horowitz. Those conclusions partially vindicate what Holder’s defenders have long maintained, that the botched gun-walking operation was isolated to the ATF Phoenix Field Division and then-U.S. attorney for Arizona Dennis Burke. The report also doesn’t go as far as Holder’s critics would have liked.
