I was home the day OKC happened and saw the photo that was circulated for less than one day regarding John Doe #3. He was definitely Muslim.
A woman who was trapped inside the Murray building was standing at a window and saw a Muslim man leave the Ryder truck and McVeigh seconds before the blast. She was trapped inside for 12 hours while doctors worked to amputate her leg in order to free her from the rubble. She her recollection was not tainted by anyone else or any reporting on television.
As well, several people walking/jogging past the building reported seeing the same person leaving the truck.
There is much, much more to that book than I can ever accurately recount here. I can only tell you that I've recommended the book to a couple of liberal friends here in town, people who thought I was absolutely nuts to believe that an Iraqi Republican Guard helped McVeigh. But after they read the book, every single one of those people is convinced. And it changed their mind regarding the war in Iraq too, given what they learned in that book.
And just to set anyone's mind at ease when reading this post that it's all some sort of nutty conspiracy, Jim Woolsey, former CIA director, has read the book and endorses Jayna Davis's research and has been famously quoted as saying that when the world knows the truth about OKC, they will owe Davis a debt of gratitude.
Yousef and Khalid Sheik Muhammad had gone there to help create an al Qaeda spinoff, a Philippine affiliate chapter, named after a hero of the Afghan war against the Soviets, Abu Sayaff. Could the al Qaeda explosives expert have been introduced to the angry American who proclaimed his hatred for the U.S. government? We do not know, despite some FBI investigation. We do know that Nichols's bombs did not work before his Philippine stay and were deadly when he returned. We also know that Nichols continued to call Cebu long after his wife returned to the United States. The final coincidence is that several al Qaeda operatives had attended a radical Islamic conference a few years earlier in, in all places, Oklahoma City."
