I think that's right. Until now, the reporters' situation has been somewhat ambiguous, which benefited that profession. They had avoided a decisive showdown on a so-called reporters' privilege and reporters had mostly avoided deciding on jail versus revealing confidential sources.
This idiotic investigation, egged on by the New York Times, is changing all that by creating clear precedent that there is no privilege and forcing a New York Times reporter to jail. IMHO, Fitz is trying to avoid going down in history as the prosecutor who busted the reporters' privilege and limited freedom of the press in the U.S., which is why he's raising these silly discovery objections.
But he's gone too far down the road. That is exactly what his legacy is going to be unless the Libby case is thrown out of court. And the curtailing of press freedom and use of confidential sources will happen because the New York Times thought it could launch a "get" on V.P. Cheney.
