Pitdown is correct. There is no, repeat, no sense or logic or even justice in such places. Life has virtually no value and to imprison someone like this (ie not in their tribe) is just another badge they wear with some sort of misguided pride. I've delivered aeroplanes to people working down there and the first thing they fit in the flight deck is a small hand gun cabinet.
I stopped doing it in the end and did something else more satisfying (and rewarding).
