Personally, i think she'll get off. Techies have testified with her saying it could happen to anyone would cause enough probable doubt to make it illegal for a jury to convict her.
I can see the school being sued for not protecting itself better, especailly in this hi-tech, hi-pornofied society.
I honestly belive its not her fault. she just happened to have it happen at a very very bad time. I've seen this happen myself at school. But then, our server got attacked and oh boy were us guys in heaven. Could we blame any one person? no. It can happen to any active connection due to trojans, and our school is "always on". Needless to say they've beefed up their security more. Its too bad some of us students know how to use it better than the admin.
