Double agents angle is interesting. Perhaps Ms. Plame leaked sensitive information to her husband and that also could be part of the investigation.
Yeah. Rove is innocent, so there's no reason to investigate him for 2 (that we know of) years. By leaking info about "Rove", they keep the democrats and Co. from fleeing the country.
"... they keep the democrats and Co. from fleeing the country."
Which way is best - in jail or fleeing the country...now there's a conundrum! :)
