Not real bright, are you?
"In sum, based on an exhaustive investigation, the specialcounsel has established the need for Miller’s and Cooper’stestimony. Thus, considering the gravity of the suspected crimeand the low value of the leaked information, no privilege barsthe subpoenas."
Since you seem to have a reading comprehension, let me explain this very complicated passage for you.
The judge is saying that the 1982 IIPA is a law. If it was broken, it's a serious felony. That was why he thought it was important for Mr. Fitzgerald to get testimony from Ms. Miller.
Prosecutors often have to prove that a serious law--such as a felony--is in play to compel reporters to give up their so-called "journalistic priviledge" of protecting their sources.
So, on the basis of a possible felony, the judge agreed to throw Ms. Miller in jail for not testifying.
After 85 days, Ms. Miller decided she should testify and she did. She testified that Libby did NOT give her Plame's name, and thus no felony has occured WRT her.
Got it? LOL
