Truancy is illegal, and homeschooling is not an option in many Western countries. So these parents will not be able to take their kids out of school...
So if you make parents legally liable for kids actions and then take the kids to an environment where the parents have no control or visibility, you are creating a nightmare of oppression.
That's why there is a legal term 'in loco parentis' which is applied to schools.
If "in loco parentis" means schools taking the role of parents, then they've certainly done a bad job of taking care of their "kids", at least in the United States...
