The list of people inside the beltway who didn't know that Plame was a spook is infinitesimally shorter than the list of people who knew she was.
I know it's a nit but if the list is "infinitesimally shorter" that means the lists are almost the same length.
For the record, I didn't know she was a covert operative until Wilson told me on national TV. Why isn't he being sent to jail for outing his wife? He obviously knew she was a covert CIA operative.
Actually, how did he know that? Did she tell him? He didn't have a position in government where he should have known that information. But he clearly knew it, and he knew it was against the law to reveal it and he revealed it anyway.
