I guess it depends on their age. If you're talking young teens, then the parents. I think as they get older, the whole idea of parenting is to encourage independence and responsibility. So I guess - say at 16 my child would be (supposed to be) taking responsibility for themselves. And if they didn't, then the consequence would be that the parents would regain that control over them for a time.

This is all in theory of course. I agree that sometimes even with the best parenting kids will have their 'moments' and phases, and in the end each individual (even my 2 and 3 year olds at some casual level) have to deal with consequences and learn about responsibility the hard way.

So how can it be stopped? Well if they're your kids I guess you have to find something that compels/convinces them that staying home or inside is the better option. If they're other kids...unless you have a curfew law there's not much you can do.
