Protoss: She was the one who gave her child away, that's true. But the kindergarten stuff is obliged to watch after them. So they have taken the responsibility.
True, maybe I read the article too hastily so I'm not quite sure if it was true negligence on their part.
I did some bad things when I was in kindergarten (not to be said out loud, google remembers...), but I don't feel the caretakers were really at fault. I was just too sneaky for them in avoiding their eyes, and they can't have a personal caretaker for each kid. My parents were contacted, I felt very ashamed, I later a became a prime quality citizen contributing to the state, I've even finished military service excellently and do not smoke (esp. weed).
Sueing the nursery for a raving kid punching another kid... I see it a bit like a school being sued for school shootings.
