They even have a rebuttal of Glennon, the typewriter repairman.
"In its broadcast last night, CBS News produced a new expert, Bill Glennon, an information technology consultant. He said that IBM electric typewriters in use in 1972 could produce superscripts and proportional spacing similar to those used in the disputed documents.
Any argument to the contrary is "an out-and-out lie," Glennon said in a telephone interview. But Glennon said he is not a document expert, could not vouch for the memos' authenticity and only examined them online because CBS did not give him copies when asked to visit the network's offices.
Thomas Phinney, program manager for fonts for the Adobe company in Seattle, which helped to develop the modern Times New Roman font, disputed Glennon's statement to CBS. He said "fairly extensive testing" had convinced him that the fonts and formatting used in the CBS documents could not have been produced by the most sophisticated IBM typewriters in use in 1972, including the Selectric and the Executive. He said the two systems used fonts of different widths. "
This is a new angle under 'factual problems':
Factual problems. A CBS document purportedly from Killian ordering Bush to report for his annual physical, dated May 4, 1972, gives Bush's address as "5000 Longmont #8, Houston." This address was used for many years by Bush's father, George H.W. Bush. National Guard documents suggest that the younger Bush stopped using that address in 1970 when he moved into an apartment, and did not use it again until late 1973 or 1974, when he moved to Cambridge, Mass., to attend Harvard Business School.
Any argument to the contrary is "an out-and-out lie," Glenn on said in a telephone interview. "
You did notice that Glennon DID NOT say that all of the features of the docs could be replicated with 1972 technology... I believe it's called lying by omission.
