They have entered Dr Mengele territory.
The nazis tried to hide their exterminations early on.
I remember reading about a resort town were the nazis were sending Jewish iron cross holders. The media was invited to go and take pictures of the Jewish war heroes living in luxury but somebody screwed up and sent a trainload of the Jews for extermination and they were machine gunned in a ditch beside the tracks. The story got out but the nazis did what progressives do and blamed it on a train crash that killed all on board (including the media who witnessed it)
