The statements from 1600 Penn and 11 Downing continue to be strong and unequivocal. There is no backtracking or hedging. Perhaps it is a matter of political timing but I honestly believe it is more likely to be a matter of military expediency. By indicating what we have found we will also indicate to those who know exactly what exists and where it was hidden (IRAQIS) what has not yet been found and therefore what remains theoretically available.
A sceneario that is overlooked is that there are missing elements we are actively tracking down. Indicating that we know what is missing and who we think has it is likely to box the 'owners' into a corner where their only choice is to use what they have or lose it.
Also, remind yourselves that the embedded reporters are gone. Stateside we have NO idea what is happening in the day to day search. What we know at this point is what information CentCom chooses to release, and by now we should be familiar with Gen Franks appreciation for information security.
