Interesting, but...
The book is a short account of some photographs that have been doctored or otherwise misrepresented to serve as 'proof' of German war crimes. There is a telling comment to the effect that, with the overwhelming plethora of genuine evidence by which so many were punished, it seems odd that these forgeries should ever have been published. The book itself is crude, possibly because no 'decent' publisher would touch it. (The author is a known 'denier'.) Some of the purported inaccuracies are not as obvious to me as they evidently were to the author. The poor focus and lighting (to the detriment of detail) in so many reminds me of photographs of the Loch Ness monster. I regard this book as a handy reference to be used with care, rather than an indisputable authority.
