'Secret police' interviewed before killing them, then put thousands to sleep

Katyn Massacre: There have been wars between many countries all over the world with the aim of grabbing land and demonstrating their strength. Regardless of the reasons in these, a large number of people have been murdered. A heart-wrenching incident related to the war was also seen in Russia (Katyn Massacre). Here the Soviet Union massacred Polish military officers and intellectuals on a large scale. There was no one else to carry out this work, but the Secret Police of Soviet Russia was the NKVD. Six high-ranking members of the Soviet Politburo, including Joseph Stalin, signed the order to hang these people.
These signatures were done on this day i.e. March 5 in the year 1940. This incident is also known as Katyn Massacre Executioner. It is said that 22 thousand people were hanged and killed. Later, graves were also found here in large numbers in the forests of Katyan. After which these murders were named as Katyn massacre. However, prisoners in other jails were also killed in a similar manner. It is said that NKVD chief Lavrenti Beria had proposed to Soviet leader Stalin that all the imprisoned officers of the Pelound be hanged.
Thousands of people were killed
This proposal was then approved by the Soviet Politburo led by Stalin. In total 22 thousand people, they were 8 thousand officers, who were imprisoned during the Soviet invasion of Poland in the year 1939 (Katyn Massacre Facts). At the same time there were 6 thousand police officers and the remaining 8 thousand people were intellectuals of Poland, including 'intelligence agents, zamindars, factory owners and lawyers'. After this, in April 1943, the government of Nazi Germany announced a large number of graves in the forests of Katyn.
USSR continued to deny till 1990
The USSR repeatedly denied the deaths of these people till 1990 and said that they were murdered by the Nazis. However, he later officially criticized the killings carried out by the NKVD. In November 2010, Russia's parliament accused Stalin and other Soviet officials of ordering the massacre. From October 1939 to February 1940 these war prisoners were subjected to lengthy inquiries, which made them feel that they would be released soon (Katyn Massacre 1940). But the real purpose of questioning was to decide who would be killed and who would be left alive.
Prisoners were kept in special camps
Reports from the NKVD suggest that if a prisoner could not be induced to adopt a Soviet attitude, he was considered an enemy of the Soviet administration (Katyn Massacre Truth Revealed). This is the reason that the order was signed on 5 March to kill thousands of these prisoners of Poland. These people included nationalist and revolutionary people. These people were kept in special camps and were considered enemies of the Soviet authorities. Then they were killed in these camps.
