Secondary case In a separate case, Federal Judge Robert Sweet ruled on February 24, 2005 that Miller was not required to reveal who in the government leaked word of an impending raid to her. Patrick Fitzgerald, the same prosecutor who had Miller jailed in the Plame case, had argued that Miller's calls to groups suspected of funding terrorists had tipped them off to the raid and allowed them time to destroy evidence. Fitzgerald wanted Miller's phone records to confirm the time of the tip and determine who had leaked the information to Miller in the first place. However, Judge Sweet held that because Fitzgerald could not demonstrate in advance that the phone records would provide the information he sought the prosecutor's needs were outweighed by a 'reporter's privilege' to keep sources confidential.
Journalist shield laws have been enacted in most states, but not at the federal level. However, those state laws vary widely but generally do not provide absolute protection and journalists may still be compelled to testify if they have been witness to a crime or if there is no other way for the court to obtain the evidence.

I thought the whole concept of "reporters privilege" was litigated all the way to the SCOTUS - and the reporters lost? Hell, aren't all of us here "reporters" too? Is Matt Drudge a "reporter"? - or does the privilege only cover people who for for the Times and the Washington Post?
