ABSTRACT
This chapter looks at reasons that have been proposed as to why surveillance might wrong someone. It describes through a number of these reasons, starting with an invasion of privacy as the most obvious. The impact on democracy is one of the social values of privacy that has been explored by Priscilla Regan. The chapter discusses trust; chilling effects; the problem of errors and false positives; power; control; and social sorting. Chilling effects are most obvious in non-democratic states, where there is a legal right to protest but it is widely known that protesters will suffer for engaging in demonstrations. Social sorting is not restricted to crime, though. It can also occur in supermarkets, through the use of loyalty cards. It is not unusual for a high-end supermarket to offer special deals to its regular customers. Finally, the chapter considers an argument that suggests there could be such a thing as harmless surveillance.
