Here's a similar video: http://video.google.com/videoplay?do...ge+2nd+Edition.
I've watched it, but these kind of things don't interest me very much. I don't really know what to think after hearing so many conflicting arguments and views, and don't really care enough to investigate it myself. Still worth watching I suppose.
EDIT: And just to clear things up, I don't mean "I don't care" in that I don't care what happened on 9/11. I mean I'm willing to accept it, and think about the facts presented to me. But I'm not about to get into a heated argument about politics and government conspiracies.
