I don’t understand how you reconcile these 2 statements. They can’t watch their kids 100% but also if the kid does something illegal, it’s their responsibility?
The reconsoliation is that as a parent, you are responsible/accountable for the actions of your child at all times, whether you are watching them or not. It's part of being a parent. Raising your children not to be little sociopaths who can eventually be trusted as adults, is a major part of parenting.
Let me ask you: Should parents be responsible for damage done by their child?
I'm not really expecting yes/no to that answer, so feel free to elaborate on it
