"[On trying to preserve glasnost (openness and transparency)] Years later, Gorbachev wanted to preserve this part of his legacy. In 2008, in coöperation with the independent newspaper Novaya Gazeta, Gorbachev formed a working group to try to create a museum of Stalinist terror. As General Secretary, he said, he had received full access to the archives. This was when he had learned that terror had been truly random, that people had been arrested and executed not for any wrongdoing, nor on suspicion of wrongdoing, nor even on specious accusation of wrongdoing, but simply because every local law-enforcement entity had to fill its quota of arrests and executions. He had also learned that at the height of the terror, when thousands of people were executed every day, Soviet leaders had signed off on these executions by the page—with dozens of names per page. Gorbachev, who had created a commission that ultimately reviewed millions of cases from the Stalin era and repealed hundreds of thousands of guilty verdicts, seemed to shudder in disbelief as he talked about the things he had learned. Here was another quality that set him apart from any Soviet leader before him: he could be shaken."
