The state isn't representing her, they are representing the people of California in presenting her complaint to the court.
Curiously, Seltzers comment about the motion is similar to what she said about Jaycee's bio-dad's efforts to see her. Are they really that uninformed about what is going on around them?
It is interesting that they want to talk to her about the defence though, do they want to use her testimony for their arguments in court? Do they think that there is a chance that could happen? That would make the trial pretty weird.
to me they are attempting to get her on there side either by persuasion or force. if they depose her, is one thing.. wanting to force out her location smacks of intimidation tactics.
