Sounds like an interesting movie where the Soviets just got things done.
Several years ago a documentary I do not recall the title of, discussed how the Russians at that time took the condemned to a very small cage, where the head was held firmly in place while the guards just blew out the brains.
Better yet, several decades ago Readers Digest had an article where in Maoist China there would be a guard standing behind a prisoner, and as the judge ruled the death sentence, the guard immediately carried it out, right there in the court room. NOW THAT’S EFFICIENT!!!
