Able Danger explained simply.

John Podhoretz from the Corner explains:

"It behaved disgracefully and in a nakedly partisan fashion, with former officials of the Clinton administration attempting to use the platform to damage the president's reelection chances. Then, after months of ludicrous conduct, out of nowhere came the brilliantly conceived and written report that set a new standard of eloquence and coherence for government documents, became a major bestseller and redeemed the commission's reputation.

Well, that didn't last long.

In a story filed at 7:10 PM, the Associated Press is now confirming all the particulars of what will now forever be called the Able Danger disaster. The 9/11 Commission staff did hear about intelligence-gathering efforts that hit pay dirt on the whereabouts of Mohammed Atta -- in 1999 -- and deliberately chose to omit word of those efforts.

And why? Because to do so might upset the timeline the Commission had established on Atta.

And why is that significant? Because the Mohammed Atta timeline established by the Commission pointedly insisted Atta did not meet with an Iraqi intelligence agent in Prague.

And why is that significant? Because debunking the Atta-Iraq connection was of vital importance to Democrats, who had become focused almost obsessively on the preposterous notion that there was no relation whatever between Al Qaeda and Iraq -- that Al Qaeda and Iraq might even have been enemies."
