The camp commandants were required to interrogate the prisoners, but the soldiers on both sides looked at it as more of a game that had to be done for those above than as a serious undertaking, and thus the man I knew would tell of the cabbage patches that members of the Home Guard were obliged to tend. Honestly, the man was almost wistful, and certainly not competely traumatised by his time there, even though he managed 2 escapes.
The only part of world war 2 that was run according to virtually all the rules of law was the fighting in North Africa; Allied POWs would stand to attention and salute Rommel when he walked passed, in that theater both sides understood themselves as professionals involved in a professional disagreement, and, unlike what you saw in Eastern Europe, in a race to the bottom to dispense with as many conventions of human society as possible.
I think our government is to be praised for doing everything to help the POWs, and, I hope that this lesson of world war 2 has not been forgotten in our newest war. This war is as much a war for hearts and minds as it is to rid us of malefactors,
