Beating around the Bush:

My view of the recent claim that Richard Clarke is lying is that the administration would not know the truth if they saw it.

But this is not another charge that the administration themselves are lying, but that they truly do not know the truth. Exhibit A: Rumsfeld says "facts change". That means that he can rely on what he wants, not on facts. Exhibit B: Intelligence is an opinion. That means that they can pick and choose the facts that they will rely on. To top it off they can even rely on facts not being reliable to safely cover their bets or rather conclusions, actions or the lack there of.

My conclusion, not having seen the previous 2002 testimony, is that they still cannot tell the truth when they see it. Further investigation and testimony may not clear up the truth, but further point to the problem that they cannot work with the cards they are dealt. After the fact, Monday morning quarterbacking is easier than 20/20 foresight. But so is Monday morning scape-goating.

Here we have an administration that wants to be able to act on a threat based on their own picking and choosing of intelligence but could not clearly conclude from the intelligence that is being presented; prior to 9-11, during current testimony, and likely during the 2002 testimony
