Well this is both funny and disingenuous, for, whilst Nick Terry gave you 200, I gave you 3, to watch you try to demolish their testimony one by one. And yet you keep ignoring those 3 . . . why?
To reiterate, at the same time, the more general point, in just one trial, the Auschwitz trial, the prosecution mainly relied on witnesses from the camp, both Jewish and non-Jewish, many of them assigned to the Political Department or the Haftlingskrankenbau (HKB), and SS men, including SS judges. Before the trial, over 400 former inmates of Auschwitz-Birkenau and SS men from the camp were interrogated. Approximately 250 witnesses testified at the trial. The original complainant was scarcely involved, as authorities found him not fully credible, and witnesses like Walter Scheerer (who testified about phenol injections) and Walter Petzold (who testified that he had seen Arthur Breitweiser shake pellets into the first gas chamber in the camp) were deemed not credible. One means the court used to test credibility was a "field trip" to the Stammlager to confirm the layout as described by witnesses as well places from which witnesses reported having observed mass executions and other atrocities. The court had to sort through some discrepancies in statements given at various times, as well as come differences in testimony from the broad number of witnesses. The charges and testimony contained very specific details about the 24 individuals on trial as well as the layout of the camp, the behavior of camp authorities, punishments of the prisoners, camp regulations, the demeanor and zeal of camp guards, transports, which SS men served ramp duty, and so on. Under the court's rules, the judges themselves interrogated the witnesses about what they testified to. The court disregarded testimonies that did not stand up to questions, that were based on hearsay, that conflicted with other testimony, or that had other problems. Still, the court found there to be credible witness testimony (along with some documents) to convict 17 defendants of murder, aiding and abetting murder, or joint murder of 1000s of victims in the camp. That is, the court 1) specifically decided, based on the factors mentioned above, that some witnesses were not credible but also 2) found by far most of the witnesses who testified to be credible - and not just on the events in the camp but as to the roles of specific individuals standing trial.
As Nick Terry has explained in terms of doing history, trials too use multiple witnesses where possible; the Auschwitz trial prosecutors were able to call 100s of witnesses whom the court found credible. Now, my guess is that the court spent more time and care with their testimony than you have with any of those whom you call pathological liars.
Again, Oscar Strawczynski. To start with. Then Yudis Trojak and Pesye Schloss.
