De Haan died because his outsider status made killing him politically safe

Evidence

Ludy Giebels aruges that the immediate motive for the murder was twofold: as De Haan was about to launch into his negotiations with the Arabs, he also was about to expose a far-reaching financial scandal related to land purchases by the Zionists—in which the leading figure was Chaim Kalvarisky, who was widely regarded as a suspicious character. I believe there was a related motive for De Haan’s murder: besides revealing gross financial improprieties, he was planning to expose Zionist officials, including Kalvarisky, for attempting to murder a Jew who refused to cooperate in what was considered to be a crucial land deal. — Ivan Davidson Kalmar, Derek Penslar, Orientalism and the Jews, 444 (#complicates, via linked claim)
