Because she's already admitted guilt.

Forgive me if this has already been posted, but an interesting tidbit from the latest AP article:

Justice Department officials declined to comment publicly on the firing and whether the matter had been referred to federal prosecutors for possible criminal charges. One law enforcement official said there were dozens of leak investigations under way. Another said there had been no referral from the CIA involving the fired employee, normally a precursor to a criminal investigation.

Remember, in the Plame case, the CIA filed a referral. Here they apparently did not--so it may not be the CIA itself that brought the hammer down on her.
