Libby should bring charges of malicious prosecution then.
Why, yes, he should.
The investigation produces not a single violation of the Identities Act. Not one.
Fitzgerald uses his one-hour press conference to conflate the meaning of "covert" and "classified", and to dissemble on whether there was any actionable crime.
Plame was clearly working domestically. No one has asserted that she held covert status in accordance with the Identities Act.
I think this will sink.
