If I remember correctly (ha!), at least one of Martha Stewart's convictions for "false statements" was for telling a federal agent she did not remember something. (I do not know how they proved that was a lie...is there some technology we do not know about yet?)
The larger question IMO would be that the DOJ would lobby Congress to criminalize Alzheimers and other forms of dementia as forgetfullness would now be on par with murder, rape and robbery!
I think it's sad and telling at the same time that our own Federal Justice Department within it's functional responsibility to uphold American law can't be trusted to properly investigate a matter and bring forth a prosecution if warranted and that an independent counsel has to be seated in order to do such things. In fact, I believe with an independent counsel, the pressure is so great that someone is going down whether or not the facts warrant such action.
One could easily argue that during the Clinton years this process was run amuck and that no matter what, the music would stop and someone on purpose would be left without a chair but it would be someone who could be sacrificed. In the case of Libby, I think it's about the same thing as we now know it was Richard Armitage who really outted Plame and my guess is Libby was sacrified by the powers that be in order to provide the masses with a scapgoat and in the end, like a number of those who went down to keep the Clinton folks safe in power, the Presidential pardon will come into play and this all would be little more than a dust spect on the American Experiment. The American People now feel vindicated and satisfied that the law breaker was dealt with and the matter now goes quietly away.
Ah, what the HeII, more wine and circus I say!!!!
