I wasn't trying to look into this subject but ended up in the rabbit hole anyway. There seems to be evidence that no one was ever gassed in Nazi Germany. Many pictures of bodies are apparently from Allied strikes. Most of the starving was due to Allied strikes on supply chains. Cyanide gas was supposed to have been used, however when cyanide gassing occurs the skin turns bright red and no witnesses said one word about seeing such a thing. Like I said, I wasn't looking for this but it definitely caught my attention.
