I believe Napolitano was lying her behind off. Watch the body language, her inability to keep her eyes forward or
even open during the more particularly unlikely answers.
At times both eyes would close for almost a full second while turning her head to the side. There was also a tendency to deflect, object, and stall whenever a particularly difficult question was posed.
I don't believe her for a minute.
