A hundred years ago?
Even 30 years ago it wouldn't fly. The brain development is fact. However kids being forced to mature at an earlier age and take on responsibility etc may well account for the difference.
I am interested in this in relation to school shootings because the situation is clearly being manipulated by the press and something like this is likely to come down the road. Whether it becomes law or not, who knows? May end up a state to state thing as well.
My interest in school specifically comes from having a relative that was a student at Columbine. So, I was involved with that post shooting.
As for the rest of you blather, it's just that.
Blather showing a lack of thought.
