If these guys were really so smart they would have issued a press release as follows:
While we were hopeful of getting a large amount of intelligence, it looks like Osama was prepared for us. He was a smarter adversary than what we had anticipated. Apparently at the first sign of our invasion, they threw all the hard drives into battery backed up microwave ovens and burned entire cabinets worth of files and faxes. It looks like most of the intelligence we had hoped to have gained was wiped out.
Instead, we've given notice to every Member of Al Quaida, "Change your plans, move, retrench, regroup, because we have your number."
