They are crucifying her, imho, because she failed to produce Rove/Libby's head definitively on a platter. She "can't recall" who told her about Valerie Flame. Well, they want her to say Libby. Plain and simple. Problem is, Miller must not want to lie. I believe it was someone else outside the WH that she is protecting, but she isn't telling anyone (even at the Times) who that source is! LOL So they're crucifying her because she's not taking down the adminstration.
They want her to say Libby but she might accidentally say Rand Beers.
