A typical ride in a department store.
The operator of the detectors can always be seen on the monitor all the information for every citizen registered in the system. As you read last book, which kind of coffee you drank and when, your medical history, what newspaper you read, what movie you saw in the movie, what do you do and where you work, home address, etc. The list is huge, huge scary!
