Kids can't tell right from wrong, maybe when they are five. These "kids" deserve to hang.
I would support trying criminals as adults at age 12. This "18" thing is lunacy.
I also think statutory rape should take into account the relative age of the parties involved. IOW, my wife and I are six days apart in age. If, the day after I turned 18, we had had sex, it would have been absurd to call it statutory rape.
Maybe a two year spread would be more appropriate - and one has to be over 18 of course.
Just me.
Sometimes laws just ignore reality.
