In this posting I will analyze Grover Furr's 2018 book The Mystery of the Katyn Massacre: The Evidence, the Solution. A copy can be found online. I've already dealt with Furr several times at this blog, demonstrating his ignorance and lack of honesty and I have already dealt with some key arguments from this book here and elsewhere. As it is still used by the deniers of history to whitewash criminals, it is useful to take a closer look at it.
It is not the aim of this post to educate beginners about Katyn - in fact, following the arguments in this post can at times require some relatively advanced knowledge of the issue. The discussion is often compact (readers are supposed to have read and understood Furr's arguments on their own) and sometimes the counter-argumentation is presented in form of links to my Russian Katyn website with more details. That said, let me give a relatively short overview of the Katyn evidence.
