Gathering Storm?

Scott Horton has an article at Harper's: The Gathering Storm at Justice.
It's based, in part, on a longer piece in a law review by an ex-US attorney, John McKay: Train Wreck at the Justice Department.
As described by Horton, in 'Train Wreck;, McKay describes a 'torrent of lies under oath' by:

Participants in the conspiracy to misdirect Congress included Attorney General Alberto Gonzales, Deputy Attorney General Paul J. McNulty, Associate Attorney General Will Moschella—the top three figures at the Justice Department—and a stream of staffers led by Michael Elston, Kyle Sampson and Monica Goodling.

There is an investigation by the Inspector General of the DoJ that is supposed to be released this spring. Scott then appears to get all optimistic as he envisions Mukasey appointing a special prosecutor. Why would Mukasey appoint a special prosecutor? And at the end he veers off into science fiction:

But we should also keep in mind that the jurisdictional basis for the Inspector General’s review is formally limited to the Justice Department and its employees. Therefore the Judiciary Committee in the House of Representatives should convene its own hearings to follow up on the trail to the extent it goes into the White House. In particular the involvement of Karl Rove and Harriet Miers must be fully tested, using the subpoena power, and invoking the power of impeachment if necessary. No claims of Executive Privilege may be lawfully raised to obstruct these hearings, and they should proceed as a matter of urgency and priority.

Congress already has plenty of material to justify an impeachment inquiry. They don't use it because of fear, I believe, fear that the administration will ignore an impeachment inquiry, and we'll just have to face the fact that we live in a de facto dictatorship. So no matter how damning the IG report is, not much will come of it.
