"Holocaust writer Grabowski faces Polish fury"
. ''Jewish Chronicle''. The ''Judenjagd'' was the German search for Jews who had escaped from the liquidated ghettos in Poland and were trying to hide among the non-Jewish population. Grabowski relied on Polish court records from the 1940s, post-war testimony collected by the Central Committee of Polish Jews, and records gathered in Germany during investigations in the 1960s.[ In a 2015 interview, he described the mechanics of the "hunt":
According to Grabowski, most Jews in hiding were given up by local people to the Blue Police or directly to the Germans. He said that Poles were "directly or indirectly" responsible for most of the deaths of over 200,000 Jews, not counting victims of the police; he explained that by "most", it could be 60 percent or as high as 90 percent.]

In 2016, Grabowski published a paper criticizing what he called "the history policy of the Polish state", and arguing that "the state-sponsored version of history seeks to undo the findings of the last few decades and to forcibly introduce a sanitized, feel-good narrative".
