I think that if every person who worked in the concentration camps was to be prosecuted, then it should have been done at the end of the war or soon after. Unfortunately because of the massive task in front of the allies, minor offenders, and indeed some not so minor offenders, were not dealt with at the appropriate time. It seems somewhat late in the day to be dealing with a guard who must have been around 19/20 at the end of the war. He would have had no say in where he was posted. He will obviously say he didn’t killed anyone himself, but there will be no evidence to that statement. What would he be charged with I wonder? Would the laws applicable today be those under which he was charged or those of the time he was conscripted? It’s very complicated, I just don’t know whether he should be prosecuted or not. Germany says there’s no evidence. No evidence of what? There will be evidence he served, and where, but is that in itself a crime. I have no answers.
