This is a video that debunks the Loose Change video. It's excellent and rather than waste your time watching the Loose Change video you should just watch this one because it follows the video along and pauses to debunk each point the video makes. It's a little long, but excellent viewing.

I just watched the whole thing. I'd seen parts of it before on youtube.com called "9/11 Deniers Speak" by MarkyX (Mark Iridian) Her does a great job of using their own words to prove what a bunch of liars or idiots they are (or both).
They say they respect the victims and their families, but when they're doing interviews w friendly Moonbat hosts, they MOCK the victims and their families.
These guys are sick.
