If things had gone differently for me, I could have been tempted to skip out without a concrete trace, take what money I had accessible to me, and run. I probably would have reassured my parents once I'd gotten to somewhere that I considered safe, true. Unless I'd been driven into a state of complete paranoia. Then I might not have re-surfaced for a good long time.
I don't think that I would choose, in a panicked, tripped-out state of mind, to claim that I'd been kidnapped. But, I don't know. I have no way of knowing, either, what was going through the mind of Jennifer Wilbanks when she skipped out and re-emerged halfway across the country. According to what she says, everything is fine with her fiancé, and the problems were mostly her vs. herself. I hope, for her sake, that it's as she says, and I hope that if getting married to this person now is not for her, that she has the strength to make sure that it does not happen.
Making a false claim of a crime is surely wrong, and it's fairly clear that it would most likely be just to charge her with doing just that. There's been a reasonably strong public outcry that she should also be made to pay back either some or all of the expenses associated with the (ultimately unnecessary) search for her. But I don't think that it would be just to stick her with the bill.

In general, I tend to approve of the idea of community service.
...and I still know, vividly, that if Sis and Darkside hadn't been at college with me to help me experience love and trust and know that my would-be marriage had neither, I, too, could have decided to take a long walk and not look back for a long time.
