It's also interesting to note that the theory some people had that the student took webcam shots of himself and that's what the school was using is impossible. The webcam could be not be activated, used or deactivated by the students. Trying to Jailbreak the laptop to allow you to do things like disable the webcam was an offense punishable by expulsion. Oh, and just for good measure, students weren't allowed to use their own computers at school.
They may not have been able to deactivate the webcam electronically, but I'll be a piece of dark-coloured paper and some tape would have worked wonders. Not that the student should have known this, but maybe something to think about if you ever have a borrowed laptop with a webcam.
The Tao is like a stack: the data changes but not the structure. the more you use it, the deeper it becomes; the more you talk of it, the less you understand.
