On the one hand, the law is very clear because there needs to be a clear line in the sand to decide if people get sent to jail or not. On the other hand, there are clearly open cultural questions about what we should get angry about. Pick any standard you like, and the majority of the world currently disagrees.
In my country of Australia we seem to be using 16. So in Australia maybe there was no crime at all. I dunno, I havn't looked in to this sort of law very deeply.
