The Finnish army photos using Zyklon B with full protective gear, gas masks, and proper handling for delousing make the casual "drop through a hatch into a room with flimsy wooden doors and glass panels" story look physically impossible. Zyklon B is highly toxic; it requires serious protective equipment, ventilation protocols, and careful handling even for lice killing. The idea of guards casually introducing it into crowded rooms without equivalent precautions.

Hoess's "confession" (and others at Nuremberg) being extracted under torture and signed in English by men who didn't speak or write it is documented in multiple sources, including Faurisson's work on how the British obtained it. Confessions under duress aren't reliable evidence, especially when the numbers could be inflated or fabricated to fit the narrative. The crematoria capacity claims (thousands per day in Birkenau's retorts) were called preposterous and ludicrous even by experienced crematorium operators like Lagacé; real throughput limits were far lower, even with continuous operation.
