Erica Grieder takes it seriously:
The [Bureau of Alcohol, Tobacco, Firearms and Explosives] is a branch of the Justice Department, which is led by Mr Holder. No one is suggesting that he dreamed up this operation, only that he has a responsibility to address it squarely and honestly, which is entirely fair. Instead his response has been to spin it as a political witch hunt. Mr Holder is scheduled to testify again on Thursday. Let's hope he is willing to be more forthcoming. At this point, the pressing threat to the department's reputation—and to that of the Obama administration—isn't coming from congressional Republicans. It's coming from the attorney-general's own stonewalling.
