Meh, even when you have the infrastructure for kids like in Germany. You still need to keep your eye on them. I've heard too many horror stories, including from personal friends of them just being dragged into a bush by a stranger and scarred for life. :/

It's a garbage world containing many garbage people and I think the "good old days" where you could just send your kid out in the morning and only see them at dinner never existed in the first place. It's just that predators can only prey on so many at once...

They're probably a lot safer in big numbers though, like if you had a group of 4 kids, each with cameras ready to film a potential attacker you could maybe give them ways in which they can protect themselves without necessarily needing adult supervision.

It's gonna be a hard problem to solve when I'll be a dad.
