To my mind, there's only one genuine question surrounding Gianna Jessen--or "Kaz deMille Jacobson" for that matter--which is:
"Has she or someone else managed to delude her into believing this obvious fabrication, or is she lying through her teeth?"
In the case of Gianna Jessen, I'm inclined to think the former (though her foster mother is another matter), while in Kaz's case, I'm inclined towards the latter.
There's another thing that bugs the snot out of me: This Jessen woman has now appeared before the House Judiciary Committee at least twice, and before at least one, possibly both, British Houses of Parliament. Why is it that nobody has apparently ever asked her "Well, that's a fascinating story, Ms Jessen, but can you actually substantiate any of it? Can you identify the clinic? Do you have medical records showing that you were diagnosed with cerebral palsy? Can you provide any medical records showing that you underwent these four operations to which you refer? Can you actually show us a birth certificate? Can you give us any substantial reason, other than your say-so, why we should believe your story?" Am I to conclude that you can waste the time of the legislatures of at least two nuclear powers provided your story is so outrageously far-fetched as to beggar belief, so far-fetched that people will buy simply because they can't believe anyone would tell that blatant a lie?
