You are right that with the opening of the files, exposing so much personal information to those who deny the Holocaust is more likely to disprove them. Yet, what their position usually stems from is not the lack of information, rather it is more like a personal conviction, distortion of facts, the unwillingness to call the black, black and the white, white.

The historians in my opinion should not be banned from accessing so much primary information. Their mission besides the event recording is to prevent the things from repeating, to keep the world conscious alive, so to speak ,and remind the human race of the existence of past, no matter what. This is something that should be spoken of, so that it will not be forgotten. Ever.
