That’s ridiculous. The SS never recruited with “Hey, come join us and gas the Jews.” People join organizations like this for power and opportunity, no different than most members of the Communists in the USSR. I doubt many of them knew of what went on in the Gulags when they decided on joining the Gulags... etc, etc.
If you can prove this guy was involved directly in the killings or was in a position where he was ordering them fine, but that doesn’t sound remotely like what this guy was involved in, I haven’t heard any arguments even from the prosecution so far that link him in any way to anything other than being in the SS and stationed at a camp.
Unless they can, its nothing more than a circus/revenge and not justice.
i guess that’s why they are having the trial. evidence is heard. both sides make an argument. blah blah blah
his Wikipedia page is an interesting read. it lays out how he found himself in this predicament. he came out of the shadows because of the moral guilt he felt and he wanted to contest holocaust deniers with first person testimony. that may work out well for him ultimately.
