"It should be understood that in a police state, instilling fear in the masses is an essential element in keeping them under control. Police brutality, arbitrary arrests, the midnight knock on the door, beatings, torture, long prison detentions and executions are all calculated ways of instilling fear..."

Theres is knock on your door at midnight. Secret police have come for you. They take you and you vanish into night. Your family is threatened or exiled to insure their silence. Your fearful neighbors "forget" you ever existed. You have become non-person. Is it Soviet Union in 1937? China in 1989? Orewell's 1984? Nexus in Yuri 41?
