These memos may be fairly good forgeries with no obvious evidence of forgery that the White House could use to justify a call to the FBI. They may have been skillfully written by a forger in an attempt to midly discredit Bush without saying anything that his commanding officers definitely would not have said about him. I find the subject matter and choice of words in these memos to be very odd and not likely to have been written by an officer in the ANG. (See post #47)
How would the White House be in a position to know if these memos are true or not? There are millions of documents relating to Vietnam era soldiers-Bush isn't going to know about these memos because they were not in his file. He has no way of knowing if they are correct or not. It could be this guy didn't like Bush tried to 'get' him-this happens a lot in the service (navy brat). Then, another officer who likes whoever the former guy is out to get...puts in his two sense. The highest ranking/most politically powerful Officer wins...but plenty of memos are written. I have a friend (female helicopter pilot) who was attacked by her new CO...a general went to bat for her and ultimately prevailed...but you can be bet there are some really ugly memos written by her CO out there-35 years from now the context will not be known.
