[link|http://z.iwethey.org/forums/render/content/show?contentid=216848|#216848]. It seems clear that if Plame was undercover, Bill Harlow shouldn't have answered Novak's question about who sent Wilson. Especially when it was easy to figure out who she was based on what he was told.
But the problem started when Libby and/or Rove and whoever else it was in the White House that talked to Rove about Wilson's mission in a way that attempted to discredit it.
I would hope that the Clandestine Service people have learned about the risks and problems that can occur when "innocuous" information is released and easily put together using tools like Google.
Cheers,
Scott.
