If I call you a mealy-mouthed anti-intellectual pompous turd-brained gutter rat with a Terry Schiavo-like IQ and all the sense one would expect from a decayed chunk of dog vomit, you think I should be fined or go to jail?

No, but having those things mean you have the ability to do things the government doesn't want you to do. The easiest way to prevent crime is to take away everyone's freedom.
Actually the intent is to make everyone a criminal to further empower those in charge. They don't want to prevent crime, they want everyone to be a criminal waiting to happen.
They kids aren't given root access, and the schools maintain an image for restoration in case of things getting ruined. AFAIK, there are browse restrictions at school, but no other filtering software is installed that I know of.
