Yes. Teenagers must be punishable according to the law. But Adult permission? I don't think so. Because the police must investigate why a teenager attempts these types of things.
It may be due to self-defense, or maybe because of an accident. But perhaps the teenager did it intentionally. Then the Law must look after the teenager and take care of his/her mental health and self development.
But Adult permission? I don't think so. - This is correct but I don't understand what you mean in this context.
keep up the good work, this is excellent.
