Fun fact: The US used Zyklon B on the US-Mexican border for decades… yet jews catch a whiff and die by the millions. Weird, huh?
The fuim a shilltion was carried out in an area of the building that American officials called, ominously enough, "the gas chambers." An article written in a German scientific journal in 1938 specifically praised the El Paso method of fuim a shillting Mexican immigrants with Zyklon B

Zyklon B (a bug spray) is a piss-poor method of trying to kill people. In fact Zyklon-B was manufactured NOT to kill people. Zyklon-B is liquid hydrogen cyanide (HCN has a boiling point of 26ºC or 78ºF) infused into an inert substance like diatomaceous earth or wood chips. Hot air blowers are needed to vaporize the HCN. Talk of Zyklon-B being dumped into a gas chamber and people dying within minutes is physically impossible.
And why would the Germans use something as inefficient as bug spray when they, for example, had 12,500 TONS (enough to kill 70 million people) of human killing Tabun nerve gas just sitting around unused? Or, you know, bullets etc.?

Leading holocaust authority Dr. Franciszek Piper about why there was so little Zyklon B residue in the walls of the locations alleged to have been homicidal gas chambers at Auschwitz-Birkenau (far less than would be necessary to kill humans). Needless to say Piper's reply was contradictory and evasive. Fortunately for those individuals interested in real history, a camera was rolling at the time and Piper's reply was captured for posterity.
