While suffering from Alzheimer's in old age, he made several public remarks that appeared to support Nazi ideology, and was tried for inciting racial hatred and similar charges.

[7][8] According to testimony from inmate Dr. Louis Micheels, Münch's last act before the camp was abandoned was to provide him with a revolver to assist his escape.

[citation needed] However, there are doubts as to the truth of this story – another former inmate, Imre Gönczy, alias "Emmerich," paints a very different picture: allegedly, Münch not only participated in selections, but also used the flesh of the dead bodies to cook a broth which was used as a medium for his microbes.

They met shortly before Münch's death, and the meeting was covered by a journalist from the German newspaper Die Welt.

[4] He was specifically accused of injecting inmates with malaria-infected blood, and with a serum that caused rheumatism; however, many former prisoners testified in support of Münch in their witness speeches.

The court acquitted him on 22 December 1947, "not only because he did not commit any crime of harm against the camp prisoners, but because he had a benevolent attitude toward them and helped them, while he had to carry the responsibility.

He was called the "Good Man of Auschwitz", who had saved prisoners from being murdered in the gas chambers.

In 1998, journalist Bruno Schirra published an interview with Münch, conducted a year earlier, in Der Spiegel.

He criticised the fact that Schindler's List had been watched directly before the interview, saying that this would have been very exhausting due to the film's three-hour length and his father's advanced age.

The Zentrale Stelle der Landesjustizverwaltungen zur Aufklärung nationalsozialistischer Verbrechen (the Central Office of the State Justice Administrations for the Investigation of National Socialist Crimes) opened preliminary proceedings.

The authorities looked through Stasi-files from the secret police of East Germany (GDR)[citation needed] and demanded Der Spiegel hand over the tape recordings of the Münch interview in order to determine to what extent the public prosecutor should act.

The assumptions of possible participation in National Socialist crimes[18] were based on three indications: The criminal proceedings against Münch were dropped in January 2000 due to "progressed dementia".

Münch appeared in the documentary film Die letzten Tage, which was released in 1999 in the US as The Last Days and in Germany in March 2000.

As a contemporary witness, he met and talked with camp survivor Renée Firestone, whose sister was murdered in Auschwitz during experiments with humans.

Lawyers Without Borders, the International League against Racism and Anti-Semitism and the Union of Jewish Students in France lodged complaints.

The reasoning of the court decision reads that all radio listeners would have understood that Münch's statements about Sinti and Roma and about NS-extermination camps were taken from the Nazi-propaganda.

[clarification needed][24] The Foundation Remembrance, Responsibility and Future (Stiftung Erinnerung, Verantwortung und Zukunft) has Hans Münch in its listings as a participant in malaria experiments on Auschwitz inmates;[25] however, he is not listed for the malaria experiments in the Dachau concentration camp, which had taken place until 5 April 1945 under the direction of physician Claus Schilling.

There was an explicit invitation to participate in the series of public meetings and discussion events on perpetrators' and victims' biographies in the Nazi regime.

The self-presentation of the SS-physicians will be examined focused on the case of the camp physician Eduard Wirths, who wrote a justification note after 1945 and who committed suicide in British arrest as well as focused on the case of Münch, against whom criminal proceedings were initiated by the public prosecutor of Frankfurt due to participation in NS-crimes after an interview with Bruno Shirra published in Der Spiegel in 1998.

The special focus of the examinations was, which ideas of humane behaviour and of fairness had been developed in the statements of the SS-physicians on the one hand, and in the judgement reasonings of the first Auschwitz Trial in Frankfurt on the other hand.Within the context of Holocaust research, Helgard Kramer reports about details in a study from 2005: Hans Münch was heard in the first Frankfurt Auschwitz Trial and even called as an expert on the 2nd and 5th of March 1964.

Until the year 2000, the public prosecutor of Frankfurt had only knowledge about the judgement of the Kraków proceedings but not about the protocols and the witness hearings.

He praised Münch, as he had prevented his selection for the gas chambers and who had given him drugs because Mansfeld suffered from a stomach ulcer.

Mansfeld was one of the internationally famous "capacities" in these fields and he was meant to provide his knowledge to the Hygienics Institute for free.
