If Libby knowingly disclosed information about Plame's status with the CIA, Libby would appear to have violated Title 18, United States Code, Section 793 if the information is considered "information respecting national defense." In order to establish a violation of Title 50, United States Code 421, it would be necessary to establish that Libby knew or believed that Plame was a person whose identity the CIA was making specific efforts to conceal and who has carried out cover work overseas within the last 5 years. To date, we have no direct evidence that Libby knew or believed that Wilson's wife was engaged in covert work. [emphasis added]
Would you summarize this to mean:
The leaking of Plame's status of employment with the CIA, covert or not, classified or not, was ITSELF ALONE, never a consideration of criminal wrongdoing.
But rather, the investigation is into whether or not there was the BELIEF that her status of employment with the CIA was covert or classified and so it was (purposefully) released.
