Actually, the reason that many of us may not have been specifically given the talk is because we were taught from an early age onto respect authority and not mouth back.
It wasnt a talk per se, but a lifetime of learning, a lifestyle.
We knew by the time we were teens how to interact with LE because we were raised with it.
I was simply told that if I did something stupid that caused cops to stop me, I was on my own and to not even waste my dime calling home for help.
You can bet THAT made me a really polite, law abiding kid because my dad meant it.
