No offense, but I think you got it backwards - - the memos are now a hoax until somebody comes up with evidence that they are NOT.
Hear, hear!Worst problem we have is people's acceptance of journalism's fatuous claim of objectivit. Accept that, and you are conned into accepting a burden of proof which rightly belongs to them.
CBS's "independent investigation" concluding that the "TANG memos" could not be proved or disproved is really a "meaning of 'is'" defense. The story line should be that CBS published as true "memos" whose provenance it could not prove. And which are presumptively fraudulent.
