Steinberg, the Left SR Commissar for Justice, was another early critic of the Terror, although all his efforts to subordinate the Chekas to the courts proved to be in vain. When, in February , Steinberg first saw the Decree on "The Socialist Fatherland in Danger!", with its order to shoot "on the spot" all "profiteers, hooligans and counter-revolutionaries," he immediately went to Lenin and protested: "Then why do we bother with a Commissariat of Justice at all? Let's call it frankly the 'Commissariat for Social Extermination' and be done with it!" Lenin's face lit up and he replied: "Well put, that's exactly what it should be; but we can't say that."

... Which reminds me of Edward Crankshaw's aside in his The Shadow of the Winter Palace: "Those who think Lenin was a splendid man will know just where to read all about him."
