The noted feminist writer Naomi Wolf, in an article warning of imminent tyranny in America, draws a parallel between the Reichstag fire, which was an inside job terrorist act used to justify the Nazi suspension of democracy, and the attacks of 9/11.
Wolf, who served as a campaign adviser to Bill Clinton, sounds as if she is writing for the Sons of Liberty or the Minutemen of the Revolutionary era in her piece, which was first published by Britain's Guardian newspaper and reprinted by the Huffington Post blog.

Though Wolf does not directly promote any particular conspiracy conjecture as to who might have been responsible for 9/11, certainly her piece describes a well-laid plot for the suppression of democracy.
