If the jury believes I. Lewis “Scooter” Libby’s lawyer, Vice President Dick Cheney’s top aide was being set up by President George Bush’s top aide to take the blame for leaking the identity of a CIA agent, and the government is relying on witnesses with faulty memories.

If the jury believes the prosecution, Libby is lying because he knew the FBI was zeroing in on him, he was aware that he had placed the president in an embarrassing position and he understood that the breach caused serious damage to the United States.
