There's a lot of good info at this site. https://codoh.com/ https://codoh.com/library/document/t...r-illusion/en/ (excerpt) ------------------------------- In 1988 the scientific team of Fred Leuchter (a US execution-expert "Mr Death" in gas-chamber technology) visited Poland, and concluded that the Auschwitz "gas chambers" could not possibly have functioned in the alleged manner – i.e., they were not gas chambers. In the following years, others would confirm the accuracy of his seminal, "Leuchter Report" . The German chemist Germar Rudolf, who worked at the Max Plank institute for Solid State Physics, is now in jail, because he likewise measured the high levels of the cyanide in the walls of the de-lousing chambers. It happens that this gas bonds permanently with iron, and iron is present in all the cement etc of stone walls. Whereas, he found none in the walls of what were supposed to be the "gas chambers" which were mainly shower units. He thereby confirmed the work of Leuchter who likewise only found remains of the cyanide gas-insecticide in the de-lousing chambers.
