I hate to say this but THE ONLY one that knows what they are talking about in this thread is ''240 is back''.
This guy killed innocent people and he is a POS but we do not have to torture him in anyway (although it would feel good and he deserves it) This would halt our progress in humanity to being as civilized as possible, some of you sound like barbarians and savages.
There are laws, rules and regulation, breaking these can lead to some heavy consequences. Sure Groink let's set him on fire and make a martyr out of him so ten more of his followers can spring up next month just so we can be happy that we bruised his flesh and blood............... there are procedures for a REASON AND TRUST ME ALL THOSE WHO ARE INVOLVED IN THIS CABIN BURNING ARE IN CRAZY SHIT, BAD MOVE, HUUUUUUUUUUUUUUGE MISTAKE.
As for the Geneva Convention and Protocols is concerned, I don't think they would even apply here 240 cause the national laws would be enough to cover all the angles but you are right in the case that they didn't the international laws would most certainly.
It always makes some happy when a scumbag suffers understandably so, however in such case the authorities must disregard all feelings and follow procedure designed by intelligent people who weigh the advantages and disadvantages appropriately.
