And what have we learned this week?

That when a highly regarded and high-ranking security expert counsels paying more attention to a strong likelihood of serious threats from a known terrorist organization, the Bush administration ignores it - but when David Letterman plays a videotape of 13-year-old Tyler Crotty becoming fidgety at a Bush fundraiser, the administration will go out of its way to tell CNN, twice, to lie about the provenance of the videotape.

Clearly, this administration knows no peer when it comes to threat assessment.
