From a Communist website:
On 31 October 2022, Tomáš Hübner, single judge of the Prague 7 District Court, sentenced Josef Skála, a well-known Marxist intellectual and former vice-president of the Communist Party of Bohemia and Moravia (KSCM), together with Vladimír Kapal, and Juraj Václavík, all three indicted, to eight months’ imprisonment, under Article 405 of the Criminal Code of the Czech Republic, for having challenged the version attributing the Katyn massacre [...] to the Soviet leadership.
The first round of the appeal hearings started on Feb. 1. From a news item:
Judge Tomáš Hübner stopped Václavík after several tens of minutes. "We're not going to prove history here, because it's absolutely clear that the Soviet Union and its units did it," he said, adding that the same arguments as Václavík were repeatedly used by staunch Stalinists before Soviet politician Nikita Khrushchev revealed how the massacre really happened.
"If you want to explain to me for several hours that Katyn was committed by the Germans, you can, but I won't believe you," the judge added to the disapproving roar of the public in the courtroom.
(Nota bene: obviously, Khrushchev never revealed anything about the Katyn massacre.)
Here's the relevant article of the Czech Criminal code:
Section 405 - Denial, Impugnation, Approval and Justification of Genocide Whoever publicly denies, impugns, approves, or attempts to justify Nazi, Communist or any other genocide, or other crimes of the Nazis and Communists against humanity, shall be sentenced to imprisonment for six months to three years.
Several points:
1. Obviously, I'm against such laws.
2. These Commies are, naturally, falsifiers of history (just like their lying comrade Grover Furr). There's no historical doubt that the Soviet Union was responsible for the Katyn massacre. Denial of this fact is intellectually equal to Holocaust denial. The Katyn deniers have been unable to muster any credible evidence for their claims and have been unable to account for the two key issues: if the Germans did it, where did the Polish POWs in question remain from May 1940 to July 1941 (we know they were neither in the POW camps, contrary to the official Soviet claims, nor in the GULAG) and which German units exactly committed the crime (we know it wasn't the unit that the Soviets officially blamed)?
3. The shouts from the Communist websites are hypocritical when the decades-long Communist suppression of the truth about Katyn using the criminal codes as a cudgel (numerous people were imprisoned for disputing the Soviet claims) is not acknowledged by the same websites.
4. The Western Holocaust deniers usually accept the Soviet guilt for the Katyn massacre (thus showing their intellectual inconsistency, since Holocaust and Katyn denial methods are identical) and try to use it to discredit the Allied evidence of the Nazi crimes (of course, without success). They also love to claim that if some historical claim needs to be protected by law, then it's at least suspicious, if not outright false. This case puts them in a bind.
