One of my favorite movies is the German film, The Lives of Others. It tells the story of an East German Stasi agent who is tasked with spying on a group of dissident playwrights. The apartment of the leader of the theatre troupe was bugged, and every night the Stasi agent settled in to listen to meetings the group thought they were having in secret. It was uncomfortable and anxiety-inducing to watch the watcher watching, to see privacy being invaded so thoroughly. Particularly because the transgressions were being recorded with the purpose of meting out harsh punishment. The anticipation of waiting for the door to be broken down was unbearable.

Surveillance (perceived or real) is a powerful tool of imprisonment.
