There is a newspaper account on this forum right at this time that Israel and Saudi Arabia, among others, are about to jointly attack Iraq. Do you believe that this newspaper report is the truth? An eyewitness claimed that George W. Bush took cocaine. Do you thing he was telling the truth? There was a radio report that the Earth had been invaded by Mars. Do you think that is true? For the record I think that all of these reports were untrue, and the same might be true of the reports you refer to. I will give some credence to a tape recording, but the only real proof that I would accept would be if you could show me where Dr. Keyes said this openly, in a press release, or on his website, or in an official transcript of his remarks.
The examples you give are from extreme papers and partisans. That is not a good example.
Two separate newspaper articles from Oklahoma papers, written independently and emphasizing different parts of the same speech have a reasonable degree of reliability. People who reported on these statements BEFORE the newspaper articles were published must also be assumed to be fairly truthful.
Your standard of reliability would allow no criticism of President Bush unless you yourself actually heard him say something or he published it on the White House web site. That is an unrealistic standard.
