You people need to stop beliving everything you hear. Just because it was posted on the internet DOES NOT make it true. How can you belive a FLASH VIDEO on the INTERNET so easily?? That is just retarted. Now, the main peice of evedence that all conspericy theorys lack is a motive. Why would the governmnet want to blow up its own buildings? Now you can speculate all you want but anyone can do that about any given chain of events. And, just so you know, that video was bullshit; most of the "facts" presented were complete fabrications. There was nothing "funky" going on about 9/11 because conspericy theorys simply never all up. People, by nature, like to make connections and find something bigger than themselves to take their frustrations out on. And to add some meaning to my words here:

As you can see there is a plethora of information efficantly debunking this theory, as with all conspericy theorys.
TLDR: Go to the links or just trust me that the 9/11 conspiracy is bullshit.
