The very thought of a Gonzales Perjury investigation makes my stomach churn

I should have been ecstatic over the prospect of a perjury investigation into Alberto Gonzales like the one proposed in this article:

Instead I am lukewarm at best, and deep down I am dreading it because I already know nothing will ever come of it. The problem is that we've let these obvious liars and villains reach such strongholds of power, they can't be investigated or stopped by any traditional means.

For example, Congress has issued Contempt of Court citations for Josh Bolten and Harriet Miers, two of Bush's top political aides, for their refusal to even APPEAR to testify with regard to the politically motivated firings at the Justice Department. That doesn't matter, though, because that same justice department has already said they will refuse to enforce the citations. So the ones we are trying to investigate are the same ones whose help we need to execute an investigation. How well is this going to work?

In a similar way, how are we going to try Alberto Gonzales for perjury? The guy is the top of the heap as far as prosecutions are concerned. He is supposed to be the most gung-ho prosecutor in the entire country, yet now he is blatantly violating the laws in a ridiculous effort to defend the leader of the free world. What are we supposed to do?
