No, that's not good plausible to you, you think the editors just tried to straight up trick people instead.
Indeed. I'm old enough to have 'starred' in more than one documentary. The TV guys arrived and asked if I could 'spontaneously' do this and that so that they can make the actual clip. The things they asked for were ones (or very similar to ones) that actually did happen... just not at the time the documentary was shot. I had this experience both in business-related and sport-related clips (krav-maga).
BTW, you are right. I don't buy the official 9/11 story either. I have no idea as to what the fu(k really happened, but I can tell the official version stinks.
