There's a movement afoot to prosecute Eric Holder for perjury in connection with his testimony to Congress over when he first heard about the Bureau of Alcohol, Tobacco, Firearms and Explosives' Operation Fast and Furious. Given that the testimony at issue included the words, "I'm not sure," and "probably," this movement strikes me as extremely far-fetched.
I admit I've had a soft spot for Mr. Holder dating back to the mid-1990s, when I was living in Washington, D.C. and Mr. Holder was U.S. attorney for the District of Columbia. I saw him speak to a small Jewish community group and came away favorably impressed. My respect for him only increased when, as a partner at Covington and Burling, Mr. Holder became involved with Philip Howard's tort reform organization Common Good.
The ATF has been shuffled between the Treasury Department and the Justice Department, and it's had problems dating back to at least Ruby Ridge. It's down there with the Department of Housing and Urban Development on the list of government agencies that have a reputation for nearly irredeemable problems. If alcohol, tobacco, firearms, or explosives must be regulated at the federal level (a questionable proposition to begin with) let the Food and Drug Administration or Department of Agriculture deal with alcohol and tobacco, and let the FBI deal with the firearms and explosives. The attorney general has enough to do, and the Department of Justice's organizational chart is complex enough already, that no matter what you think of Fast and Furious, the mere existence of the agency in the current set up is a scandal waiting to happen.
