I recommend having a look at these films, which have been physically decaying in storage for more than 50 years while kept secret, and only now are being digitized and released to the public.
This is a pretty amazing revelation of some of some of the most devastating man made events the world has ever seen.
I refrain from other editorializing, for your safety, and to promote you thinking for yourself.
Enjoy!
