It was on those ‘confessions’ that the omnipotence of the police rested. Their regularity, their inevitability, and their nightmarish character had invested the political police with a mysterious power, a basilisk look, which no Soviet citizen could hope to withstand or elude. No matter how innocent he might be of the crimes attributed to him, the citizen knew that he was helpless and would not be allowed to prove his innocence. Subjected to ceaseless day-and-night ‘interrogation’ over weeks and months he was sure to reach the limits of endurance, to collapse and confess, and thus supply his persecutors with the ‘evidence’ they needed. In recent years this technique was not frequently applied in Russia, although it was readily exported to Czechoslovakia, Hungary, and Bulgaria. But as long as the technique was not officially and publicly exposed the mainspring of the machinery of terror remained intact.

At that mainspring Malenkov's government struck a telling blow when it ordered the arrest of the officials who had been in charge of the investigation into the ‘doctors' plot’, and when it publicly exposed the criminal manner in which they had extorted their ‘evidence’.

Officials who had the extraction of ‘confessions’ on their conscience must have read with a shudder the communique about the release of the Kremlin physicians. The shudder must have been felt in every dark office of the political police throughout Russia. Every man, high and low, in the service must have wondered whether, if he ever again tried to extort confessions, he would not be made to pay for it with his head or at least his freedom. The masters of terror were themselves terrified, and the mass of the Soviet people must have been thrilled by the mere thought that henceforth they might be free to defend their rights against their persecutors. Malenkov's government explicitly assured them of this.

It was as if a long, severe, cruel political winter was over, a Siberian winter which had lasted for more than two decades. Spring was in the air; and, politically, the whole of Russia seemed to be clearing the snow from her doorsteps in those memorable April days.

Great historical changes in the climate of a country sometimes show themselves more directly in ordinary scenes of daily life than in the official documents, public statements and pompous editorials, from which an unimaginative historian will one day construe a dead picture of those days. The official documents and even — who would have supposed it? — the editorials of Pravda made exciting reading. But they conveyed little in comparison, for instance, with this description of a seemingly trivial street incident given by Mr. Knudson, one of a group of American journalists who visited Moscow early in April.

‘To the amazement of Western nationals in Moscow and the Russians themselves, the Americans were allowed to use their cameras freely.’ Under the Stalinist obsession with secrecy this was unthinkable. Yet the ban on the use of cameras was not rescinded. Mr. Knudson himself was stopped in Moscow by a policeman when he was taking photographs and was asked to produce his passport. ‘I left my passport at the hotel, and as the policeman tried to talk to me in Russian a large crowd gathered. One of the Russians was a woman who spoke English. I told her I was one of the visiting newspaper men. "Let him go. He is an American,” she told the policeman. And he did.’ (The Manchester Guardian, 10 April 1953.)

This little scene in which a policeman, disregarding his standing orders and instructions, did what a woman from the crowd told him to do, sums up the new mood.

But can Malenkov's government afford to destroy the mainspring of the terror? Dare he throw out of gear the whole machinery of terror?

Malenkov almost certainly intends to tame rather than to undo the political police. It is always difficult and dangerous for any dictatorial regime to try to liberalize itself. Popular grievances pent up in previous years may be so intense and bitter that, once the floodgates are thrown open, the grievances may overflow and threaten all groups associated with the previous regime, including the reformers.

The reformers may then take fright, shrink from the consequences of their own liberal gestures, and surrender to the adherents of the terror.
