Probally been "lured" (if we can call it that) to speak. Of course it's good of her to speak, it's her father afterall, but it loses all it's respect because media is abusing the whole stuff and it gets unpersonal and just another thing media can use on their front page. But by all means, as I said, it's good that she wants to talk some last words, but again I think that media has encuraged her to do so, and therfor I am not sure if I like it or not.
Just look on Norwegian newspaper today for example, half of the page is covered with a picture of her, and headline "heartbreaking speech" and a lot of articles around her.
