"The Atta and Jarrah Show"

The basis of the official narrative is that 19 devoted muslim warriors, willing to commit suicide in an attack against its enemies, hijacked 4 aeroplanes on 9/11 and slammed them into the WTC towers, sacrificing their own lives in the process. I just want to remind viewers and readers of the videos of (presumably) "the last will" of Mohammad Atta and Ziad Jarrah, which seem to suggest very strongly, that Atta and Jarrah was NOT dedicated, suicidal jihadis, but rather imposters who couldn't keep their pokerface as they posed as dangerous and serious suicide bombers and terrorists.

And what does that mean in the whole, official narrative of 9/11?
