Bill Safire has a very good column on the meaning of the CBS forgery and what should be done first: Because no ethic requires a journalist to protect a source who lied, the guy should be found and prosecuted.
"Appointing independent reviewers should not be a device to duck all others questions; thats Kofi Annans trick to stonewall his oil-for-food scandal. But lacking the power of a grand jurys subpoena or testimony under oath, victimized CBS cannot put real heat on the perpetrator or conspirators. We have hard evidence of crimes by low-level operatives here - from wire fraud to forgery - as well as the potential of high-level political involvement. Is no prosecutor prepared to enforce the law?"
