Is this really a question on the age of consent, worlds a completely different place to when I was a teen, foc me my 14 year old nephew admitted to smoking pot the other day and I would be surprised if he hasn't had some sort of sexual experience with one of his many girlfriends which he seems to change on a daily basis.
My, and probably many of your son's, daughters, nieces and nephews break this law well before they reach the legal age, should we lock all of them up too?
