I came across this article in my Facebook feed and thought it had a good point and is helpful/realistic. It talks about teaching your kids how to identify 'tricky people' instead of just telling them not to talk to strangers. For example, "Tricky adults ask kids for help. If a safe adult needs help, they'll ask another adult." Not sure how wide spread that idea/lesson is...thoughts?
