This is one of those frustrating things. You're just not allowed to not be scared with kids. If you aren't scared of letting your kid walk to a pond, you get punished for it. If you're not scared of the kidnappers, you have to be scared of the police. None of it is rational, it's different how many of us were raised, yet if you try to opt out the law gets involved.
Stranger kidnappings are basically unheard of. It's never been a safer time for kids in terms of crime like that.
That's why they don't go outside. You can teach them to run from the panel vans; teaching them to run from the police (who were called by some Karen) is much more difficult.
