Zyklon D was dispensed by a MD?
Try for real comparisons, not trying to schock!
I, a former SS physician, witnessed the dropping of Zyklon B into simulated exhaust vents from outside the gas chamber. Zyklon B began to work.....I, Dr. Hans Munch hereby attest that, as an SS physician on duty in Auschwitz in 1944...society gave Dr. Munch permission...just as we give the pharmacist permission.....I'm sorry it conflicts with your world view.
