If the Killian memos in question do turn out to be forgeries
http://www.washingtonpost.com/ac2/wp-dyn/A9967-2004Sep9?language=printerwho might have produced them, and how did they get to CBS? And will CBS ever share that information, or will they honor the confidentiality of their sources?
There are really only two possibilities if they are forgeries. (1) Someone did it in an attempt to harm Bush; (2) Someone even more demonically clever did it to seed CBS with bogus docs, knowing they'd eventually be discredited, hoping that would make the
Democrats look ridiculous (and I note that the DNC is sending out emails trumpeting the memos) and make the media shy away from any more investigation into the TANG accusations.
I don't think #2 is totally tinfoil-hat. All the perpetrator would have had to lose would be credibility with CBS if CBS had decided the docs were not legit, and no one else would ever have known.
The problem (for both Dems and Republicans) is that if the election becomes a fight over the past, the past is much easier to tinker with. On the other hand, the evidence that GWB has been a failure over the past four years is much more overwhelming. Which is why I think Kerry and the rest of us need to pound away at those last four years and not obsess over TANG.
