Whatever the culture, our borders are shrinking. Which means that if we intend to travel to other countries and meet other cultures, we better learn fast that ignorance is not an excuse. The fastest way to teach those who are not smart enough to get informed is through experience, or example. Grope a CC or shout "BOMB" (ah-ah! Funny!) at the airport at your own risks.
Lemain, once the "brats" are big enough to travel on their own and legally responsible, they better learn fast what "legally responsible" means. I don't think that "my parents didn't teach me well" is considered a valid excuse in any legal system.
