This is from a series of articles done by Slate's Jeremy Stahl on 9/11 Conspiracy Theories.

The man who created the single most influential piece of propaganda about the 9/11 conspiracy is now ambivalent about the movement he helped make popular. "There's a certain thing called tact that you need when you're dealing with the public," says Dylan Avery, director of the film Loose Change, released in 2005 and since viewed tens of millions of times online. "And I think that is a certain approach that a lot of people lack."
Avery should know. He has been accused of being a traitor, a spy, or—slightly more charitably—just plain "sloppy." According to 9/11 conspiracy proponent Michael Ruppert, the movement has been hurt by its acceptance of some of the (relatively speaking) more absurd notions that were featured prominently in the early versions of Loose Change, notions that he says were planted as disinformation by those looking to discredit conspiracists. "That's one of many reasons why I completely cut myself off from the 9/11 Truth movement in 2004," Ruppert says. "They just swallowed too many poison pills."
