German Concentration Camps Factual Survey Film (aka "Memory Of The Camps") # http://www.iwm.org.uk/corporate/projects-partnerships/german-concentration-c...
These war filmreels and others like it have been available for quite some years since even the 1980's in various forms. The longer restoration could probably be found on youtube in months. https://www.youtube.com/watch?v=e8IufpmR3y8 There is probably much more from the era (camps / nukes / etc) in both government and private vaults. Even now, and with new wars, they still do not want you to see what war is, for fear it will be found pointless and the purveyors guilty and shut down.
