I found his actions bizarre at times. My favorite moment was when he picked up the blue cup from under the table and took a swig. The cup covered most of Edward's face with the bottom of the cup pointed at the camera. I also thought the loud rip of paper from his pad was strange. Having worked as an expert witness with lawyers some of his actions were not that unusual.
I caught that paper rip. I was wondering if it was a lawyer trick? It was rude. I think Cheney heard and gave him a sidelong glance.
I don't think Edwards' immaturity was lost on Cheney...Cheney knew exactly what Edwards was doing...
