Somebody mentioned that it is easier to get her to come back to Idaho than to extradite her from Hawaii. I agree. But if she simply disobeys the order to produce the kids in Idaho and stays in Hawaii, I think it is far less likely that a court would order extradition for contempt of court. They could also potentially challenge the Idaho order on jurisdictional grounds. Just speculating here but Lori was not in Idaho very long. If she is still an Arizona (or Hawaii resident) legally then I think there is a good possibility that Idaho lacks jurisdiction.
I don't know, I think they are both guilty as heck of many things. But innocence could also explain their behavior. If they know the kids are perfectly safe somewhere with trusted friends to protect them from all this drama, I could understand why they might get angry with all the attention from police, press, etc.
We'll know within 5 days I guess. If they produce the kids this might all just go away until there is significant evidence to charge them in a death, which may never happen. If they don't I think they will be arrested in Hawaii and Idaho will have to battle getting them.
