The "official" holocaust story was that jews were first (a) gassed to death, and then (b) cremated -- although, there are also claims they were buried in mass graves near the camps, for which there is exactly zero evidence.

Fred Leutcher was the #1 gas chamber expert in the entire world. Only the USA had executions (of murderers) by gas chamber. The states that did this needed someone to come in, either build or maintain the gas chambers, and educate the executioners on how to do it so they wouldn't end up killing themselves. Fred Leutcher was the go-to man for this expertise.

Because of this, when Erst Zundel was on trial for "muh holocaust denial" in Canada, he hired Leutcher to go investigate the supposed gas chambers in Auschwitz and other camps.

His expert conclusion was that there were no gas chambers, and there were no structures that could have ever been used as gas chambers.

He also testified in Germany over the same topic for a different defendant.

He is the only man in history who was certified by both the German courts and the Canadian courts as an expert witness on the subject of gas chambers in the German labor camps. And his conclusion is that it was all made up. They never existed.

The other side of the debate has NEVER presented any evidence to refute this expert testimony.

Fred Leutcher is still alive today (I think -- he is in his 90's) and still does interviews and still explains why there could never have been any gas chambers.

There WERE delousing chambers to kill lice, which is why the prisoners had their heads shaved, went through the delousing chambers naked, and then issued new clothing, with their old clothing burned (in case they had lice in them). But these chambers could not have been used to kill humans.

Leutcher also did an investigation into the crematoriums. Yes, those did exist. He was not en expert, so for the Zundel court case, he went to American experts who built and used crematoriums of that time. He learned from the experts in that field, so he could include this information in his reports to the court.

His opinion is that the crematoriums were used for dead bodies. The disease of typhus was spread via lice. At first, the Germans did bury dead bodies in the fields, but they quickly realized that the typhus could spread from the dead bodies underground and contaminate the water table. So, they built crematoriums to destroy the chance for typhus to spread.

However, doing the math, he concluded that in order to kill 6 million, they would still be cremating them today. So, not physically possible.
