Statement on 9/11: “I have been researching the physical evidence associated with the building collapses of 9/11 for several years, primarily through analysis of the videos of the destruction of the buildings. There are numerous ‘smoking guns’ for the use of pre-planted explosives, implying that the hijackings were merely a cover story for a false flag operation.”
