How about the perp be sentenced to be in a room alone with the parents of this child who are armed to the teeth and he is tied up????
I like that scenario.....
One of the tools the parents would have in their possession would be very large TIN SNIPS, LARGE BOLT CUTTER,, and a couple of saws. MAybe even a SAWZALL.
Then we can provide several rounds of small calibre ammo along with the hand guns.
Just my way of thinking about what justice would really look like....
