If we watch closely when Alberto goes before the committee to answeer questions about his contradictory statements, we'll see a Monty Python style farce being enacted. Neither side will have any understanding of what the other side is talking about.
The committee members will follow a mainly logical, rational procedure of asking logical, rational questions of Alberto, expecting logical, rational answers. Alberto will answer that he would never fire a US attorney and replace him or her with a loyal "Bushie" for political reasons. And Alberto will be telling the truth, as he knows it. To Alberto, replacing all members of government with loyal Republicans is not politics, it's merely fulfilling Republican ideology. He truly believes that he is an instrument of Republican prophesy and is justified in taking any action necessary to fulfill that prophesy.
Alberto has taken psychopath lessons from George Bush for so long that he actually believes that the Bush team goal of making the US government a subsidiary of the Republican National Committee is his right and duty, because he is a Republican, and the political manipulation of the Department of Justice is not to be questioned. It's downright heresy for anyone to question a Republican who's working diligently to make everything all Republican, all the time.
The farcical nature of the hearing will become clearer as it progresses to total impasse. It's not that the questioners and the questioned are diametrically opposed, it's that they're not even on the same diameter, or even part of the same circle.
The tragedy of the thing is that the committee members will be absolutely, totally unable to understand that they are dealing with a mind that is completely alien to them and their rational, logical thinking, and Alberto will be absolutely, totally unable to understand why these people are asking him totally irrelevant, stupid questions.
It will be an exercise in futility, a perfect demonstration of dealing at cross purposes, with no common ground on which to meet. Alberto and the committee will never be able to understand the basic premise from which the other is operating. They are each alien to the other.
