The problem with that theory is the Colonel mentioned. He had retired by the date shown.
Note, they have a new witness to quote on what was said about Bush:
"Another former Texas National Guard officer, Richard Via, also said that the documents were fakes but that their content reflected questions about Bush that were discussed at the time in the hangar at Ellington Air Force Base, where he had a desk next to Killian's.
Via said he and others he worked with "remember the physical, and him going to Alabama was an issue." He said Killian "made notes and put them in his files about things like that."
Killian kept the files because "he was trying to cover his ass," Via said. "He was always worried something would come back on him."
He said Killian's secretary "would type them up, and he'd put it in his desk drawer and lock it.""
