For a while I thought maybe she was assaulted in some way and was completely confused about when it happened and who was involved, but after the polygraph comments were refuted by her ex-boyfriend that sealed the deal for me -- it's almost axiomatic that because of her field of study she would be well informed on the subject, her denials to Ms. Mitchell seemed odd, but it appears clear now that she in fact did lie about it. That's not a minor detail, it's a very big deal.
