The Communist Party of the Russian Federation and a number of other pro-Soviet Russian politicians and commentators claim that the story of Soviet guilt is a conspiracy and that the documents released in 1990 were forgeries. They insist that the original version of events, assigning guilt to the Nazis, is the correct version, and they call on the Russian government to start a new investigation that would revise the findings of 2004. A number of Russian historians and organizations such as "Memorial" openly admit the Soviet responsibility, pointing out inconsistencies in the alternative versions – primarily the fact that another major mass execution site in Mednoye was never under German occupation and contained remains of victims originating from the same camps as those killed in Katyn, killed at the same time, and even though it was only exhumed in the 1990s it contained well preserved Polish uniforms, documents, souvenirs as well as Soviet newspapers dated 1940.
