Why do people think 9/11 was an "inside job" based on the way the towers collapsed or building 7? What was the motive in "faking" the collapses, instead of just making them REAL by crashing more planes into them(if they were "fake" in the first place)? After a very short time of thinking, the whole "inside job" theory sounds stupid to me. I am open to an intelligent discussion on the subject though.
