The issue of civil liberty has been debated a lot over the past few years, especially after the 9/11 attacks, but let me describe to you what is probably the most perfect police state that exists.
In this world, every conversation you have is automatically recorded. Everything you say or hear is stored in a large database. The name of every person you have ever talked to is noted down as well as how frequently you talk to them. The state has the ability to control how far your voice carries and whether you are able to shout at all. In fact, you are only allowed to communicate with other people using the tools provided by the state. Anything you say can be erased before it reaches another person's ear. More importantly, anything you say can be instantly altered before it reaches another person's ear. In fact, you can be coerced to say anything you never said.
The state knows exactly where you are at any given moment. It has the ability to teleport you and imprison you instantaneously and without warning. The state can change your name if it doesn't like it and provides no way for others to connect your old and new name. More importantly, the state can alter your height, your gender, your age and any other aspect of your physical appearance with a few keystrokes. It can make everyone equal in every aspect of physical appearance and ability.
