“Whether he wrote ‘Down with Big Brother’, or whether he refrained from writing it, made no difference. Whether he went on with the diary, or whether he did not go on with it, made no difference. The Thought Police would get him just the same. He had committed – would still have committed, even if he had never set pen to paper – the essential crime that contained all others in itself. Thought-crime, they called it. Thought-crime was not a thing that could be concealed forever. You might dodge successfully for a while, even years, but sooner or later they were bound to get you.
It was always at night – the arrests invariably happened at night. The sudden jerk out of sleep, the rough hand shaking your shoulder, the lights glaring in your eyes, the ring of hard faces around the bed. In the vast majority of cases there was no trial, no report of the arrest. People simply disappeared, always during the night. Your name was removed from the registers, every record of everything you had ever done was wiped out, your one-time existence was denied and then forgotten. You were abolished, annihilated; vaporized was the usual word.”
George Orwell, 1984
