Sorry for this being an old post.
Check this out! Some more stupid propaganda ( http://www.auschwitz.org/ )
I have recently been to Auschwitz, and I can assure you that a lot of forgeted up stuff happened up there, to address rumors of the gas chambers not being true that may be true or false. But even without them i would refer to the experiments of Josef Mengele, he experimented on humans basically in one case the attempted change of eye color by directly injecting heavy metals into the eye.
Propaganda you say?
