[Source:] Reinefarth went on to live a normal life similar to other Holocaust perpetrators living in West Germany including SS-Obersturmführer Strippel from Majdanek concentration camp, and Oberscharführer Fiedler from Chełmno extermination camp. In December 1951, he was elected Mayor of the town of Westerland, the main town on the island of Sylt. In 1962, he was elected to the parliament (Landtag) of Schleswig-Holstein. After his term ended in 1967, he worked as a respected lawyer. Despite numerous demands by Poland, he was never considered guilty, as the German courts ruled, there was no evidence of him committing any crimes whatsoever. Instead, the government of West Germany rewarded him with a General's retirement pension.
I read that 'despite Polish demands for extradition, he was never convicted of any war crimes.' Yet how could even a Nazi with known involvement in such many genocides able to thrive, as a mayor and parliamentarian?
