"There are no neurotics or geniuses or failures or fools. There are only neurotic moments, flashes of brilliance, failed opportunities, and stupid mistakes." -David K. Reynolds
A much better idea is to teach children to read other people's emotional state in the moment; to develop their intuition and teach them to trust it. It's that intuitive ability that will allow the child to escape arbitrary danger and to thrive in general.
There aren't good and bad people that wear different jerseys.
There will be some hardcore thug who looks like the scariest dude that will protect your child in an emergency.
There will be some teacher/innocent looking person that wrongs your child in some way.
When you need help, approach someone in a crowd and ask. Don't wait for someone to approach you. The odds that the person you choose to approach is dangerous are pretty low. Whereas the odds are higher that a person who chooses you -- notices a confused person in a crowd, walks right up to them, and offers to help -- is potentially dangerous. That's the stalker strategy.
Corollary: Expect people to be very nervous when you walk up to them in public and ask if they need help. They are going to assume, with justification, that you are more likely to be stalking them than the average passerby.
Everybody has to learn it eventually because the world doesn't get less dangerous as you grow older.
In short: If a kid has good boundaries and is empowered to act on their judgment without having to articulate why (which is often difficult even for adults and can be impossible for a kid), the odds are relatively small they will be victimized in some significant way. Even a toddler can decide if they want a goodnight kiss and can signal that by enthusiastically turning towards you and throwing their arms wide open or by turning their face away if the answer is 'no'. Respecting that instinct and cultivating it is tantamount to an invisible shield which will keep out most predators. And it's not just protection against potential sexual predation. It generalizes.
