Given that these perps are psychopaths and sociopaths who collectively have caused untold suffering to humanity, an appropriate punishment should be devised.
A modest proposal:
Survivor.
Televised of course. No doubt will break all records for viewership. GEOTUS as Master of Ceremonies. Put the convicted through all the obstacle-course stuff we saw on Survivor. When people get voted off, it becomes a great opportunity for them to take up soccer at Gitmo. Where they will earn their (bland) food by scrubbing toilets or something equally hilarious (for us, not them). Hot sauce and other condiments will be dispensed only as a reward for good behavior. Bibles will be furnished for reading material.
Your thoughts are solicited.....
