According to the defense attorney, there is no doubt that the informant tried to downplay the conversation he had with the investigation officer, and it was also claimed that another investigation officer, Eyal Zeitoun, stated in his testimony that the investigation officer was not allowed to talk to an informant about the interrogation, in fact he confirmed that the interrogator Saban's actions were wrong.
It was argued that the conduct of the investigation team raises questions and concerns that the informant's operation was not free of biases, and therefore the informant's operation and its products should be disqualified.
In the arguments of counsel for defendants 2 and 3, the defense attorneys repeated the arguments made by counsel for defendant 1, and added additional arguments, including the question of how the informant knew how to start a conversation concerning the city of Lod, and to tell Muhammad that he had a brother-in-law from the city of Lod, from the Zeituna family, even though according to what he said in his interrogation he was not briefed on this. (P. of April 4, 2021, p. 206). As noted above, the interrogator explained that the informant officer who briefs the informant before entering the cell is exposed to facts from the file he receives in the summary that is forwarded to him, and it is possible that the informant knew how to talk about the city of Lod and the Zeituna family from what he received from the informant officer.
In the words of the informant, to which the defense was referred, the informant explained (April 4, 2021, p. 187 ff.) that the person who prepared him for the dubbing process with Muhammad was his operator and another officer, and according to him, the additional officer told him that he was going to be a suspect "sitting on a murder case" (April 4, 2021, p. 188, s. 11), and nothing more. The informant added that the same officer may have also mentioned where Muhammad was coming from, but he did not tell him about the incident. The informant insisted that the officer did not tell him that it was a murder by strangulation, shooting or car-ramming, because according to him, "never in any case is such a thing said" (ibid., p. 189, para. 13).
