To me, that shows they already had their minds made up and convicted Libby because they didn't have Rove or Cheney.
Absolutely.
Or convicted him for the same reason that some here say Fitz wanted the conviction -- to make it easier to go after Cheney, Rove, Bush -- or even Reagan posthumously. They are all still sure Reagan was behind Iran-Contra, which was some terrible crime against humanity, the Constitution and Jim Wright.
