Since you have never watched it you sure know a lot about the show. Where is his body?
2. Multiple Germans who were in Hitler's bunker and even those who saw his dead body and participated in his partial cremation survived the war and lived for years afterwards. Their testimony sounds credible.
3. An enormous amount of detail is known about Hitler's dental work, especially as complete X-rays of Hitler's head and teeth have been found. This information matches the drawings of Hitler's teeth that were in the Soviet autopsy.
4. Käthe Heusermann, the dental assistant who was asked by the Russians to identify Hitler's teeth and dental work, lived in west Germany until 1995. She had all that time to deny that she had been shown Hitler's real teeth, but she didn't do that.
5. Some of Hitler's teeth were put on display in Moscow in 2000 and were examined more recently by Western experts. They concluded that there is absolutely no doubt that these are Hitler's teeth. - link
6. Russians have sometimes been known for distorting the facts, but the personal testimony of those who worked on finding Hitler's body and on the autopsy sounds credible. Here is a show that has a lot of interesting interviews with people who were involved with Hitler's death: link
7. Hitler's last will and testament, which is undoubtedly authentic, stated that he wanted to die in Berlin. It is entirely inconsistent with his known state of mind and with logic, that he would have risked being captured.
8. And another major reason for being skeptical about the thesis of the Hunting Hitler show is the author of the book it was based on: Jerome Corsi. In 2011 he published a book that was supposed to show that Obama was not born in the United States. If Corsi had managed to nail that down, Obama would not have been president for another 5 years.
Hitler’s body, along with those of Eva Braun, Goebbels, and the other bodies found in the bunker (including Goebbels’ family, and Generals Krebs and Burgdorf) were moved to various locations after the war, finally being buried at a SMERSH facility at Magdeburg in 1946. Circa 1970 the KGB undertook a mission to dig up all the remains, cremate them, and dump the ashes in a tributary of the Elbe River.
