Slight changes in condition may have been sufficient to push the balance one way or the other. Yet the burden of proof here lies with the deniers. They claim to prove that gassings could not have occurred in the gas chambers. To make such an argument, they need to demonstrate that their proposed mechanism of Prussian blue formation must be operative in the gas chambers under the precise conditions under which they were operated. Their task is daunting.
Any claim made on the basis of the absence of Prussian blue is at best empty speculation.
Add to that the evidence that cyanides were indeed present in the homicidal gas chambers, that witnesses claim that gassings took place there, that the perpetrators admitted to their crimes, and that 1 to 1.5 million people were deported to Auschwitz-Birkenau and never returned, and we can label Rudolf's work willful distortion of the evidence.
