If you aren't the target, you have very limited 5th Amendment rights before a Grand Jury and they can force you to answer. That is why it is such a big thing that prosecutors inform people coming before Grand Juries that they are targets.
That's why this whole thing stinks. Libby doesn't get a target letter, can't have a lawyer in the GJ when he testifes and puts himself in legal jeopardy. The WH staff is bound by Bush's directive not to discuss their testimony, whereas Miller, Cooper, and Russert (how can he even claim to report objectively on this story?) leak all their GJ. So there's a stench from Libby that comes with the indictment and his side of the story isn't out there.
Why does Fitzgerald believe Russert's side of the story?
True, but you always say, in that case, "I don't recall," "I think maybe, but I could be wrong." You Clinton-ize.
I believe you can refuse to answer, only if you refuse to answer all questions. If you answer one then you are cooked. I could be wrong though. Although Mark Lavin yesterday on Hannity radio opined as I have. Thanks for the input.
