"going to Israel to question a witness"

Witness statements at war crimes trials were crucial in both securing convictions and, especially in the immediate post-war trials, informing the world about what had taken place during the Third Reich.  The later trials of the 1950s and 1960s had the difficulty of locating people – many Jews had emigrated to countries such as the USA and Israel, and gave testimony in the form of deposition.  There could also be questions – at least from the defence’s perspective – about the reliability of memory, as in some cases witnesses were giving statements fifteen to twenty years after the events took place. 

Here is the transcript of the witness testimony of Abraham Sutzkever about atrocities which took place in Vilna.
