I'm probably the only one who finds it strange that Miller's lawyer has been arguing with Scooter Libby's lawyer whether his release of confidentiality was coerced and therefore doesn't allow her to reveal her source. If it weren't Libby, how could that argument be relevant? I suppose it's one of those legal fictions, where Fitzgerald can't legally conclude that Libby was the source based on the dispute over confidentiality. Or perhaps the topic of interest isn't that Libby was a source, but exactly what he said, that he's willing to release Miller from confidentiality so she can reveal that information, but isn't willing to reveal it himself. Or perhaps he has revealed the conversation and the prosecutor is looking for corroboration, in which case Miller went to jail to protect...who knows?
