There's been a ton of 911 conspiracy videos on google video, youtube, and even an internet online tv station on shoutcast TV, devoted only to conspiracies. Whether you believe in them or not doesn't particularly matter. If you come in calling them conspiracy nuts, that's fine. I don't believe in ghosts but still enjoy a good horror or haunted house episode. Even if you think it's an absolute fiction, there's plenty of religious people that still read/saw the Da Vinche code. Search for 911 Conspiracies Debunked and listen to both sides.
There are 5 videos in the series so I won't embed =P, but I'll Link it. This video was removed from google video. Probably democracy now! sent them a letter or something, so I don't know if youtube will have this up for long. One of the things that stood out is; They said the explosions under the crumbling point couldn't have been possible because the building fell at freefall and the fuel couldn't have reached lower floors. The building was smoking for a good long while before it toppled. Plenty of time for the fuel to seep to lower floors.
I believe it's good to question EVERYTHING and it's rude of the people who get offended by investigation rather than the other way around. Debate is good thing, the problem is there's people on both sides just saying things to make a buck, and not able to really come to anything conclusive due to a bizarro faith they put into their theories. That goes for BOTH SIDES!
