Nothing there ! lol ! boy where do you get your info! The amount of government spy agencies and special ops gear there could sustain a war from New York city for years! Not to mention the gold and other assets stored in vaults ,that no one has mentioned! But besides all this, building number seven had the unique position to be able to control the type of operation required to be able to destroy the twin towers! Building number seven "Command Center" held too much evidence to be left standing!
Some times making sense requires a little common sense !
But however unwittingly you named building number seven the brain ,you couldnt have been more correct then if you had actually known something!lol!
