The network's statement said typewriters were available in the early 1970s which were capable of printing superscripts. CBS pointed to other Texas Air National Guard documents released by the White House that include an example of a "th" superscript.
That superscript, however, is in a different typeface than the one used for the suspect memos. Document examiner Sandra Ramsey Lines of Paradise Valley, Ariz., who examined the documents for the AP, said she was "virtually certain" they were generated by computer.
Lines said that meant she could testify in court that, beyond a reasonable doubt, her opinion was that the memos were written on a computer.
This is going to end up doing serious damage to CBS's credibility. Someone's gonna have to take the heat.
