A work colleague and I have a saying "you've never been really screwed over until you've worn a uniform" we both spent a long time in uniform. More often than not you are sent into a situation hamstrung by politicians who are more concerned with their re-elections than if you come back in a body-bag.
As for this torture 'scandal' going on. It looks more like something out of a hollywood prison film about cruel warders. I've been subject to resistance to interrogation. Not fun but no one pulled my fingernails out either. Didn't need to. Given enough time I'm pretty sure they would have got all they wanted. It's the time it takes to break someone down and get what you want. This looks more like a bunch of undisciplined jerks getting their rocks off.
We all know that anyone of ours taken by paramilitaries have a minimal chance of being returned. Just ask Gerry Adams and co if they would return any of the troops his confederates took. Also ask if he could detail their last hours. If he had the balls to do it and not lie.....it had better go on well after the kids were in bed. That kind of thinking can also effect the actions of troops who have their hands on the 'enemy'.
I recall in the '80s that a patrol from 3 Para (I think) was taken to task for steaming into a village and beating up some of the inhabitants. The suitably bruised barman of the local was interviewed saying what "animals" they were. What wasn't reported was that earlier on that day an 18 year old private had lost both his legs in a landmine attack. As the partol returned past the village, the villagers turned out and began doing impressions of the seven dwarfs while jeering and shouting insults to celebrate. The troops were not allowed on camera as the barman was to defend their actions or claim any mitigating circumstances.
