PoliceState is a Carnivore client by Jonah Brucker-Cohen that attempts to reverse the surveillance role of law enforcement into a subservient one for the data being gathered. The client consists of a fleet of 20 radio controlled police vehicles that are all simultaneously controlled by data coming into the main client. The client looks for packet information relating to domestic US terrorism. Once found, the text is then assigned to an active police radio code, translated to its binary equivalent, and sent to the array of police cars as a movement sequence. In effect, the data being "snooped" by the authorities is the same data used to control the police vehicles. Thus the police become puppets of their own surveillance. This signifies a reversal of the control of information appropriated by police by using the same information to control them.
