I've seen that picture at least 100 times and never noticed that.
You're right. The kids aren't even looking at her. Strange.
It must have been one of those 'staged' fotos, under the direction of some fotographer, don't you think ?
I have seen other fotos of Rachel Corrie, and she doesn't look like a maniac in those.
The final fotos of her, after she had been crushed by a bulldozer are very sad, and I won't post those here as it doesn't seem respectful to the parents.
I don't think we can judge her personality by that one staged fotograph, or declare her a maniac from one fotograph, and to be fair, Corrie's parents grief at her death can be no less traumatic and painful than the grief of the Boim's whose son was killed in Jerusalem by a bullet on his way to school.
