Any intelligent operation will have multiple levels. You have the people you want to be blamed–such as the mostly Saudi terrorists on 9/11–then you have the actual operational background. These two may well not have known of the Lord and Taylor cameras, perhaps as an operational oversight, perhaps due to the mission being rushed.
On 9/11, it would not have been necessary for the hijackers, or Osama Bin Laden, to have known the second aspect of the operation, which was the planting of bombs. That part could have been, and likely was, compartmentalized.
It may be that this Saudi, who appears to be on the verge of a legally sanctioned–an Obama-sanctioned–escape, was the intended fall guy, but that they got to him much too quickly.
I have no proof or even evidence for any of this. I am speaking off the cuff. I have often found, though, that the larger the number of possible perceptual filters you can create, the better the eventual match when you have sufficient data.
