"The state reverted to capital punishment in the Cultural Revolution. Red Guards sometimes put victims on trial in the street after leading them in chains through the city. In extreme cases a defendant would be forced to confess before kneeling down and receiving a bullet in the back of the head. It was widespread practice for the families of the deceased to be sent a bill for the price of the bullet. Perhaps a million people died by execution or by their own hand. These gruesome rituals had a purpose. They were designed to make the maximum number of people complicit in the butchery and compliant with the policies of the authorities. Mao had no intention of doing things on the sly as Stalin had usually done. He wanted a society of active participants in the terror. According to one estimate, up to a million of the victims of the Red Guards were thrown into the prisons, the laogai or the reform-by-labour centres; but the true number may have been much higher. Moreover, the families of victims were discriminated against. Even people who were neither killed nor arrested could suffer in various ways. Some were dispatched for re-education by means of menial labour. Others were simply demoted. Psychological trauma was a pervasive phenomenon across the country."
