What's wrong with waiting until a certain age to kill a convicted child? For starters: It is a child. Secondly, a wing or cell block full of children waiting to get old enough to die boggles the mind. On the other hand, it could be a real money maker; one could sell lots of chances to tour the facility and view the condemned. Maybe a spitting room could be provided in order to enhance the experience.

Oh, yeah. You have convinced me.
