Some Poles were complicit in , or indifferent to , the rounding up of Jews . There are reports of neighbors turning Jews over to the Germans or blackmailing them ( see " '' szmalcownik '' " ) . In some cases , Poles themselves killed their Jewish fellow citizens , the most notorious examples being the 1941 Jedwabne pogrom and the 1946 Kielce pogrom , after the war had ended
