The ethical foundation of these matters also seemed to be there until this trial. Therefore, after sincere examination of my conscience, I cannot find any feelings of guilt and expect with a clear and peaceful conscience the verdict of the Tribunal. K. Final Statement of Defendant Sievers[43] Your Honors, in his opening plea, my defense counsel already stated quite openly and frankly that all events were going to be presented with which I was in any way connected, and in this hour which is so important to me, I can state to the best of my conscience that when I furnished my defense counsel with information, and during my own examination on the witness stand, I always spoke the full truth. I have, in fact, had the satisfaction to hear my testimony confirmed by a witness for the prosecution. During my examination as a witness on the stand, I said quite truthfully that the experimental subjects to whom I had talked in connection with the last experiment in Natzweiler had confirmed to me that they were voluntary subjects. Witness Nales, witness for the prosecution, confirmed my testimony during his examination on the 30th of June in this courtroom. With regard to the charge of participation in the malaria experiments, I have stated that I had nothing to do with malaria experiments. Witness Vieweg, called by the prosecution, confirmed this testimony of mine, as also did witness Stoehr. I testified that the two experimented subjects whom I met in connection with the altitude experiments, in reply to a question by me, confirmed specifically that they had volunteered. Witness Neff of the prosecution confirmed this voluntary status of the witnesses. Likewise Dr. Romberg during his direct examination stated on the strength of his own knowledge that my testimony was correct. The only experimental subject whom I met in connection with the typhus experiments upon my definite question regarding the voluntariness of his testimony, confirmed that this was so. My testimony was also confirmed through the affidavit of a former prisoner, and witness, Grunzenhuber, contained in my second document book.
