When the wheels came off the bus

The engine fell out, the brakes failed, and the driver tried to run away:

It's true that the claim that the firings were performance related set off a chain reaction of events. Most importantly it pushed some of the US Attorneys to defend their professional reputations.

But this is the classic case of mistaking the symptom for the disease. As McNulty could see, refusing to give any explanation for an unprecedented firing of multiple US Attorneys with active investigations or prosecutions of prominent Republicans simply wasn't tenable. Vague lies about performance problems was the least worst option available.

Frankly, simply reviewing the multiple instances in which Bush Justice Department officials threatened the firees with attacking their reputations if they didn't go quietly, I have real doubts whether any of the performance related line started with McNulty. But it hardly matters. 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. Let me repeat that, the whole point of the cover-up is a recognition that a full revelation of the underlying bad act is not survivable. Indeed, the cover-ups are usually successful. And that's why they're tried so often. Just look at this administration. They're the ultimate example of this truth.
