And the problem with show trials would be?
The fuse was lit when the White House ordered the DOJ to fire the list of US Attorneys for hurting Republicans and not damaging Democrats. A really good cover story might have kept the thing hidden but a blanket refusal to discuss the matter -- in a department the Congress oversees -- was never going to cut it.
There's this old line the wise folks in Washington have that 'it's not the crime, but the cover-up.'
But only fools believe that. It's always about the crime. The whole point of the cover-up is that a full revelation of the underlying crime is not survivable.
This is about finding out what really happened. All the effort that has gone into preventing that tells you the tale.
Kleig lights are the best disinfectant.
NOTE And Josh may take credit for lighting the fuse. I'd ask why, say, Nags still has a job.... But I think it may be dawning on everyone, Nags and his masters included, that Josh doesn't want Nags's job. He's in the process of inventing a better class of gig, and more power to him.
