The whole 911 thing is so ridden with strange things I have no doubt there's something really fishy hidden there too. No, I don't believe in stupid conspiracy theories, but I am inclined to think it's possible that the buildings ultimately might have fallen like they did because of a failsafe system built in them after the previous bombing attempt and meant to facilitate controlled demolition instead of letting the towers fall onto Manhattan and cause much more damage. I'm certain there's something wrong or hidden in the big picture nevertheless, whatever it might be. Perhaps something less sinister like a huge structural design flaw that's kept hidden, or something. Whatever it is, we're not told about every aspect of it for some reason.
That Osama's death would be a hoax is also pretty incredible, but I also find incredible that in the death picture Osama looks 1:1 right down to the lip position as he did in a ten year older photo and superimposed they fit pretty much exactly. That IS pretty weird. Most likely it is just coincide, but then again, it's incredible that if you'd catch the most wanted man in history, you'd not take any proper photos or video or make any proper such documentation or even conduct a proper autopsy for the history books, but instead pretty much instantly get rid of the body in a way that nobody can possibly get their hands on any of it or prove it?
Why on earth would anybody do that if it wasn't fishy in some way? Most likely he is dead, though, but again, I don't think we're told everything about it. It could be something like the picture of dead Osama might have been too gruesome to release as is, and they had retouched it using previous picture. Could be.
I don't think there's a way to find out exactly what happened in any government operation or scenario; usually I don't believe reality is nothing like the CIA cloak and dagger games in movies, but everything is usually based on some truth to the matters, and if even half a percent of what movies suggest would be true, well, that would not only be believable and what I'd do if I was running a secret service, but also definitely make things appear somewhat fishy in tight scrutiny.
