Believe me when I say that this video is very reassuring in two aspects. 1) It goes to show that "leaders" of the movement are in the dark to what the "official story" of the collapse of the World Trade Center Towers woudl be and 2) It goes to show that a Truther is not helplessly lost when it comes to evidence and reason. Though I do not believe that we have an official conversion here, but Mark does a great job in challenging the lies that this young man has been told about the official story.
