In return for immunity from prosecution for war crimes, Erich von dem Bach-Zelewski stated at the Einsatzgruppen Trial that "the principal task of the Einsatzgruppen of the S.D. was the annihilation of the Jews, Gypsies and Political Commissars". Roma in the Slovak Republic were killed by local collaborating auxiliaries. Notably, in Denmark and Greece, local populations did not participate in the hunt for Roma as they did elsewhere. Bulgaria and Finland, although allies of Germany, did not cooperate with the Porajmos, just as they did not cooperate with the Jewish Shoah.
