“Since I entered politics, I have chiefly had men's views confided to me privately. Some of the biggest men in the United States, in the field of commerce and manufacture, are afraid of something. They know that there is a power somewhere so organized, so subtle, so watchful, so interlocked, so complete, so pervasive, that they better not speak above their breath when they speak in condemnation of it.”
― President Woodrow Wilson, The New Freedom
The University of Alaska has recently completed a 4 year study of the collapse of WTC Building 7. They have posted the data and supporting information here. There is an open reward of $45k for refuting their study.
“...For we are opposed around the world by a monolithic and ruthless conspiracy that relies primarily on covert means for expanding its sphere of influence–on infiltration instead of invasion, on subversion instead of elections, on intimidation instead of free choice, on guerrillas by night instead of armies by day. It is a system which has conscripted vast human and material resources into the building of a tightly knit, highly efficient machine that combines military, diplomatic, intelligence, economic, scientific and political operations. Its preparations are concealed, not published. Its mistakes are buried, not headlined. Its dissenters are silenced, not praised. No expenditure is questioned, no rumor is printed, no secret is revealed.”
― President John F. Kennedy (audio of speech)
I think that the above information is adequate to convince a thinking person that they are being lied to about the events of 9/11. I know a lot of intelligent people who are convinced that 9/11 official story is true. I'm not sure they've really looked into it much. Many intelligent people know they are smart and might shrug off something as being below them. Who has time to waste on flat-earth theory, right? I see their point. But at the same time, the information available without even researching it is enough to spark the interest of an intelligent person.
This quote from David McGowan in his piece titled "Wagging the Moondoggie" gets pretty close to why so many people believe hard to believe things with such a high degree of certainty. Although he is speaking of the moon landings, I think his comment applies to 9/11 for exactly the same reasons.
"But that is not the main reason that people cling so tenaciously, often even angrily, to what is essentially the adult version of Santa Claus, the Easter Bunny and the Tooth Fairy. What primarily motivates them is fear. But it is not the lie itself that scares people; it is what that lie says about the world around us and how it really functions. For if NASA was able to pull off such an outrageous hoax before the entire world, and then keep that lie in place for four decades, what does that say about the control of the information we receive? What does that say about the media, and the scientific community, and the educational community, and all the other institutions we depend on to tell us the truth? What does that say about the very nature of the world we live in?
That is what scares the hell out of people and prevents them from even considering the possibility that they could have been so thoroughly duped. It’s not being lied to about the Moon landings that people have a problem with, it is the realization that comes with that revelation: if they could lie about that, they could lie about anything.
It has been my experience that the vast majority of the people who truly believe in the Moon landings know virtually nothing about the alleged missions. And when confronted with some of the more implausible aspects of those alleged missions, the most frequently offered argument is the one that every ‘conspiracy theorist’ has heard at least a thousand times: “That can’t possibly be true because there is no way that a lie that big could have been covered up all this time … too many people would have known about it … yadda, yadda, yadda.” "
