I think Lenore Walker misunderstood what Nancy was asking last night. When Nancy asked about Jodi lying about the abuse, Nancy meant that it never happened and that Travis never abused her. I think Dr. Walker meant that Jodi had been lying when Travis was alive and said that Travis never abused her. We've heard of women who deny the abuse and say they ran into the door, fell down the steps, etc. I don't think Dr. Walker would say that a woman who was never abused could be classified as a battered woman.
Is this the exchange you are referring to?
Lenore Walker on NG:
NG: "If Jodi Arias was lying about Travis Alexander abusing her, could she still be a battered woman?"
LW: "Sure. Battered women lie all the time. That's how they stay alive, that's how they deal with the shame. Lying is not new for battered women. But it isn't just whether or not someone is a battered woman that's important in these cases, as you well know, Nancy. It doesn't give them a free pass just because they are a battered woman. It is really used only to help us understand whether of not they were in fear of what was happening - that they would be seriously harmed or killed at the time they commit a homicide. So that's what we have to look at AND THAT'S NOT WHAT I'M HEARING IN THIS TRIAL!!!"
