You know how, since the dawn of "stranger danger," it has been the duty of fathers to warn their children of it? In the UK, doing so might be illegal depending on the specific stranger and how you define the danger. Telling your daughter to avoid soccer hooligans? You're in the clear. Warning them to avoid the migrant hotel full of asylum seekers who are known to get rapey? That gets you a visit and an interrogation from the police.
