I live very close to this girl and I remember this story because I was a graduating senior in high school when it happened. From what I can tell, based on interviews in the paper and everything I heard about the story, the girls lawyer father pretty much forced this issue, I don't think she really cared too much. As for the plagerism, the paper that reported on it also published her supposedly plagerized work in some sort of teenage opinion column. For the most part the plagarism was trivial and I blame the paper as much as I would blame the girl for having absolutely no fact checking at all. Yet they had the nerve to go back once she was infamous for suing the school and say she was plagarizing too. It seemed very immoral to me. I don't believe that kind of plagarism is illegal, she certainly didn't profit from the pieces she wrote. edit: it is however, immoral, and there is no excusing it. Still, I wouldn't rescind her acceptance, she did work hard to get those grades lawsuit or not. Unless she plagarized her application essay I don't think it should effect admissions.
The girl's house got egged regularly after the lawsuit and her rescinded acceptance probably hurt, college is the most important thing to many graduating seniors. I feel very sorry for her, I believe the school handled things poorly to begin with. Certainly I (and most of us) would have been happy to share valedictorian with someone else, and I have a feeling the girl was too. I bet its hard to convince a parent of a child with a disability to share such an honor after overcoming so much, with someone who technically didn't deserve it. Especially a lawyer with an overinflated ego.
Blame an overbearing parent, not the girl. She did not get what she deserved.
She will probably be better off not going to Harvard anyway, maybe learn something about being a normal person instead of never really working a day in her life.
