Campos: Loose Change Certifiably Insane
Paul Campos, a law professor at the University of Colorado and a longtime columnist reviews the "Truth Movement":
First, the 9/11 Truth movement features a wide variety of claims, ranging from the quite plausible (the government's negligence prior to the attacks was not wholly displeasing to certain members of the Bush administration), to the wildly improbable (the WTC towers were brought down by controlled demolitions), to the certifiably insane.
The latter category includes claims such as that 9/11 was a plot to steal $160 billion in gold buried under the WTC (this theory is put forth in the film "Loose Change," which has purportedly sold 100,000 DVD copies); that no airplanes hit the towers (the theory here involves sophisticated holographic imaging equipment); and that the passengers supposedly killed on the four flights hijacked that day were all herded onto United Airlines Flight 93, which landed safely in Cleveland before the passengers were transferred to a top-secret NASA facility.
If you're curious, you can also find plenty of stuff about how it was all really the work of Satanists, or an elite secret society that was set up several thousand years ago by space aliens. (A morbidly amusing sidelight to the 9/11 Truth movement is that many of its members have become convinced that other members are either unwitting dupes or conscious agents of the government, who are propagating obviously outlandish theories for the purpose of discrediting the movement as a whole.)
