That Hennessy keeper has got away with the nazi salute by saying he doesn’t know who hitler is?!!
I read the explanation, and they criticised his lack of education/knowledge more than his morality, which I thought was interesting.
My initial reaction, like you, was very skeptical, but I got the sense that it was a valid reading of the situation, because they sounded more surprised by his stupidity than anything, and they said that they studied his responses carefully and didn't get any sense that he was blagging anything or not taking things seriously. He actually didn't know the historical situation or the issues around it.
