From mid-1937, Stalin drew up ‘arrest quotas’ for each area of the Soviet Union, and the percentage of those arrested to be shot. But, as with the Five-Year Plans, over-fulfilment was encouraged. Terror was heaped upon terror, as people petrified of being denounced got in first with their denunciations. No crime was needed, no proof required. Guilt was of little consideration and innocence of no consequence.
