In this connection, we must consider the convenient line of the defense. By limiting the Ruff-Romberg-Rascher experiments to the 10 subjects, we find that they further allege that no deaths occurred in those experiments as opposed to a considerable number of deaths in the Rascher work. But the witness Neff, in describing the first day of the experiments, emphatically stated that the first series of experiments _was not carried out on volunteers_. Furthermore, the defendant Ruff was also present during these experiments. (_Tr. p. 622._) The defendants’ contention that the experiments were in two groups is _explicitly denied_ by Neff. He testified that Romberg not only experimented with Rascher on the original 10 subjects, but also on a large number of other prisoners. The distinction fabricated by the defendants cannot possibly be credited in the light of Neff’s testimony. On being asked the question whether Romberg experimented only on the 10 original subjects, Neff replied: “Experiments were conducted not only with these ten persons but, for example, in a series of experiments which Romberg also conducted on a large number of other prisoners. The distinction which the defense counsel tries to make between experiments included in the report to the Luftgau or of death—it is impossible for me to make this distinction and to distinguish between those which fell into one category or the other.” (_Tr. p. 691._) Which is to be believed, the testimony of Neff, plus one’s common sense, or the self-serving statements of the defendants? This is a question the Tribunal must answer. There is no such thing as half a murderer. These defendants are responsible for those murders or they are not responsible. There is not one scintilla of evidence to support the ridiculous contention that a group of volunteers, segregated for use by Romberg, wore different colored shirts so he could tell them apart and were treated with the greatest deference. But that is just what Ruff and Romberg ask the Tribunal to find. It is absolutely impossible in the face of the record.
