Blender Head beat me to it, but this is just an awesome (not to mention awful) statement.
Can you actually follow your own logic (and I use that term in its loosest sense, here) in this exchange?
You do obviously know what they DID; you're offering arguments as to their complicity, e.g. that their actions or inactions aided in this great monolithic unexplained conspiracy to bring down the three buildings.
Ergo, if you know "what they did(or didn't) do", and state that they were just following orders, then by basic extrapolation, YOU KNOW WHAT THEY WERE TOLD TO DO.
Well, that, or you're full of crap.
