A few years ago I saw a documentary on The Discovery Channel (or some other similar network) showing all the evidence that the moon landings were a hoax. It was a very convincing piece, though I doubt it's actually true.
In that same vein, I today watched Loose Change, a documentary alleging that 9/11 was a US government plot. Again I find myself with a movie that asks a lot of interesting questions and presents quite a bit of alleged evidence, but I can't help but be skeptical. In truth, the most reassuring thought is that I don't honestly believe that our government is capable of a cover-up of this scale.
So I link with a caveat: This is going to be controversial and may very well be absolute crap. But a small part of me can't help but wonder...
