In contrast, Libby was indicted for perjury in a criminal case where but for the fact he didn't tell the truth, he would not have broken the law.
But it does wind up looking like Libby lied to protect someone else (Cheney). Loyalty is one of the greatest attributes the WH has, and it mkaes me wonder if they don't think thre's a chance a crime could have been committed or at least that they could be railroaded for one.
