One thing he says is there are no gas holes in the ceiling, but then you come to find out the whole place was blown up in 1944 and then reconstructed as a monument, so holes in the modern facility are irrelevant.
The Nazis also photographed the construction work on the cremas/gas chamber buildings. In December 1942, they took a picture of the construction work underway on Crema/Gas Chamber 2. The picture included the roof of the gas chamber room shortly before its completion and before it was covered with dirt. Behind the train’s engine, the four chimneys on the roof and the shadows they cast are clearly visible.[10]
Why it is difficult to find the holes in the gas chamber roofs today? In late 1944, the cremas/gas chambers buildings in Birkenau were dismantled and blown up by the Nazis in an attempt to erase the physical evidence of the genocide.
