I have a cousin who's a teacher and all I hear is how difficult it is to keep the kids attention or get them to follow through on assignments etc. At a time when America's schools suck so badly on math & science scores, it's great to see kids using abstract thinking to either find the solution, online or figuring it out for themselves.
Instead of contacting the authorities they should consider hiring a couple of the kids who shredded their ipads as security consultants. Punishing them would only foster an environment where kids would be too scared to learn.
Finally, suing apple because the kids blew through poorly configured software, managed by the DoE IT staff is like suing Porsche because someone intentionally drove over glass & nails and flattened their tires.
