2. The Cyanide Stains

157.Van Pelt is a professor of cultural history and completely ignorant of chemistry, so was in no position to testify on this subject.
158.Roth did not give evidence at the trial. Roth had originally analysed Leuchter's samples, supporting Leuchter's conclusions. Later he said:--  
"If I had known the samples came from Auschwitz I would have _come to a different conclusion..."
159.The evidence of a man who will change his conclusions to suit the premises is of little value
160.When giving a summary at 7.115 of Roth's views (received at second hand, and not tested by cross-examination) Gray J does not mention that Irving produced to the Court colour photos of the fumigation chamber at Auschwitz, showing that the blue cyanide stains had permeated right through the brickwork.
161.Even if the concentration of cyanide required to kill 500,000 human beings is less than the concentration required for routine delousing of garments, Roth's suggestion that cyanide produces a surface reaction which will penetrate no further than one tenth of the breadth of a human hair appears to be irreconcilable with the evidence of the colour photos of the fumigation chamber.
162.It is, moreover, a matter of common knowledge, which can easily be proved by the production of real evidence if the Court of Appeal declines to take judicial notice of it, that plaster is a very rough, porous and coarse material. It defies common sense to accept that a gas such as hydrogen cyanide will not penetrate into such material deeper than a few fractions of a millimetre.
