That's a good point, some parents can barely be said to be raising their children at all. Should they be? In other words, is saying you had nothing to do with little Bob's education be enough to absolve yourself of responsibility for his actions?
I think in general it's accepted that the person who is looking after the child while shit happens is responsible for looking after them at least. But I wonder if we should hold parents responsible for actions which take place when the child is not under anyone's supervision. Who is ultimately responsible for the child's actions?
Do parents have de-facto supervision obligations?
