This OP is in need of information about Eric Smith and whatever his case was.
Also the title is very imprecise, it looked to me like you were asking about people who murdered children, but in the OP, you’re asking about people who as children murdered others.
Let me or another GD Mod know what can be added to the OP to fix it.
I’ll fix the title in the meantime.
I am obviously not familiar with Smith’s psychological condition. Institutionalizing a person who presents a clear danger to other people if free is a separate issue from criminal punishment and maybe that’s why he remained locked up for so long,
If it wasn’t that he was dangerously insane, well, in my opinion, a 27-year criminal incarceration imposed upon a child is barbaric.
