"The Logic of Surveillance"
Surveillance is part of the system of control. “The more surveillance, the more control” is the majority belief amongst the ruling elites. Automated surveillance requires fewer “watchers”, and since the watchers cannot watch all the surveillance, long term storage increases the ability to find some “crime” anyone is guilty of.
This is one of the biggest problems the current elites face: they want the smallest enforcer class possible, so as to spend surplus on other things. The enforcer class is also insular, primarily concerned with itself (see Dorner) and is paid in large part by practical immunity to many laws and a license to abuse ordinary people. Not being driven primarily by justice or a desire to serve the public and with a code of honor which appears to largely center around self-protection and fraternity within the enforcer class, the enforcers’ reliability is in question: they are blunt tools and their fear for themselves makes them remarkably inefficient.
Surveillance expands the reach of the enforcer class and thus of the elites. Every camera, drone and so on reduces the number of eyes needed on the ground. The Stasi had millions of informers; surveillance reduces that requirement and the cost of the enforcer class.
