Re: Educate kids about danger without scarring them for life?
I have a general rule which is never ever go anywhere without telling me or the grown up in charge first.
In your scenario, OP, I think I'd just be keeping a better eye on the kids for now. I grew up in the 80s in BC and when Clifford Olson (google him) was killing children none of us were allowed to even walk to school alone. After he was caught, life returned to normal and we were kicked out of the house until the street lights came on!
