Dude, were you listening at all? Have you reasearched this at all? No. You only believe what the media intitally proposed to the masses. You are the governments ideal puppeted citizen. You are basing your comment, or your post, solely, on what the governement said or the news. Can you really trust the government? A select few of Americans who are mostly business people? How can you trust them? Do you know them all personally? They're just normal people. They can be anybody. And they can also lie just like any other perosn in The USA.
Also, if you look at the site the professor mentioned, there are TONS of SCIENTIFIC EVIDENCE. That's straight up FACTS. F-A-C-T-S. Not views, not believes. FACTS. Government said rocket fuel from the airplanes melted the steel beams. Well, the FACT is they lied. Jet fuel burns at a max temperature of 1,800°F. Steel doesn't melt until around 2,700°F. Government lied. So sorry, don't deny it. Facts are facts. Don't get angry at the facts.
