Public executions in Leningrad were only performed during WWII. Hanging was also used only during WWII.
I enjoy your assertiveness. Did we continue WWII in 1946?

The woman on the previous video yells, "Разоблачить! И еще больше можем разоблачить, которые остались! Никто не стесняйтесь, не бойтесь!" How can it be referred to the war criminals who had been already arrested and trialed? Sounds a little bit inconsistent with your interpretation of the video.
