A friend and I have a disagreement, they are adamant that after WWII the allies executed most concentration camp guards and gestapo. I was under the impression from what I read that the vast majority ended up surviving and being freed, either because that much mass execution was a logistical nightmare, there was a lack of evidence for who was responsible for what, and they just needed society to move on in the 50's.
What happened to a majority of them? What happened to the ones who were not summarily executed?
Why were many of the Gestapo, SS, and other Nazis given such light punishments following the war? features an incredibly in-depth answer written by u/kieslowskifan that discusses why and what happen. It may be of interest.
