I have issued this challenge to truthers many times, go to your local college or university and ask a professor of civil engineering (Preferably tenured since they can have whatever opinion they want) if 9/11 was an inside job or not, and show your evidence for your side.
The two out of two truthers I challenged just won't do it. Ramy (or Romeo) Scutaro and Wais Karimi keep saying that they don't have to do that because the professors will agree with them, at least they say that in some manner. OK, then why aren't you asking? You guys clearly do not want to make the effort and do not want your fantasy to be popped.
Come on guys, get off your computer, take a couple of hours and go to the place of learning and ask a professor. It's not like they're going to laugh at you, they'll just say you're misinformed and will tell you why, most likely anyways. Go ahead, just go to the university and ask.
