One of the reasons why the nanny state is good is so stupid people are forced to look like they're doing the right thing and our children aren't bullied by the majority of idiots into letting loose with stupidity. (Having witnessed all high school kids in the entire schooling system of a country not wearing motorcycle helmets and half the teachers unapologetically doing the same in government uniform, with occasionally interjection and announcement by the headmaster and police for them to stop breaking the law, please... the second highest road death rate in the world. )
Many people Don't think and need to be taught or forced to not be completely stupid. Death isn't really a good teacher. It kind of doesn't really let u learn from the mistake, because you're dead.
