As no crime was committed Libby had no motive to lie.
This leads to only two conclusions:
1. Libby was mistaken in his testimony.
or
2. Tim Russert is a lying Son of a Bit— and perjured himself to get Libby convicted.
It should be noted that Tim Russert took no notes during his conversation with Libby. Tim Russert made no notes after his conversation with Libby. I find it very difficult to believe that after talking to the lawyer to the second most powerfull individual in the United States that Tim Russert did not take notes of this conversation so he could write an article or present it on television.
I think Russert is a lying Son of a Bit—!!!!
Wanna see something sad...read Bob Woodwards account of his conversation with Libby, vs. Libby's account. The stuff Libby says he said to Russert, Woodward says he said to him.
