I don't believe the official story of 9/11 because I know the official story of 9/11!
During the past 15 years I have not met a single individual who, after doing research on the subject, switched from questioning the official narrative of the events of 9/11/2001 to believing the official narrative of those events.. It is always the other way around. Why do you think that is? There are good reasons for this, and I will try to explain this phenomenon right now.
The term "conspiracy theorist", perhaps the most misapplied description in our vernacular, is often used to describe 9/11 truthers. Perhaps that term does apply to a segment of the 9/11 truth movement. But in most cases a more accurate description of 9/11 truthers is probably "expert", or "scholar", or "researcher." You see, much of the doubt cast on the official narrative of the events of 9/11 has not come in the form of speculated accusations, or "theories." In fact, it has come in the form of questions that have been raised after a careful study of the official and undisputed events and details.
