When the subject of documentation of the Holohoax comes up, Exhibit #1 is always the Protocol produced during the Wannsee Conference of 1942. They even made a propaganda movie about it: Conspiracy (2001 film). Kenneth Branagh and the other top Nazis plan the dirty deed right before your very eyes!

SPOILER ALERT: There was a conference, but they're lying about what was discussed and concluded (see The Wannsee Conference Myth). And the "sole surviving copy of the Protocol" is phony (see The Wannsee Conference Protocol: Anatomy of a Fabrication).

Bet nobody here saw that coming!

EDIT Just noticed this in the page for Evidence and documentation for the Holocaust:

The Nazis used figures of between 9 and 11 million for the Jewish population of Europe, as evidenced in the notes of the Wannsee Conference.

They just cannot quit!
