In December 1984 Reder had written an open letter to the citizens of Marzabotto expressing his profound repentance for what had happened in 1944. Once released and living in Austria he retracted his apology admitting that it had just been a means of obtaining his release.
When Reder was released in 1985 he was flown to Graz in Austria where he was met with full military honours by the Austrian Defence Minister Friedhelm Frischenschlager who, at that time, was a member of the right-wing populist Freedom Party of Austria (FPO). This led to a political scandal internationally as well as in Austria. Frischenschlager later expressed regret for his actions.
