It seems to be a common misconception that authoritarian, fascist methods to prevent crime don't work. They do. They always worked, they always will. The problem is that it takes away the citizens' privacy as well. If the only argument needed for increased surveillance is to deter crime, then we've essentially doomed ourselves into a society of surveillance, because it always works. Lack of privacy, even in public houses, needs to be seen as problem, not as something that can endlessly be given up in the name of security. Freedom and democracy always were and always will be unpredictable, that's what's so cool about them. To hell with the CCTV cameras. Of course they work to deter crime, the problem is that they also work to control the population, and that's a real problem that needs to be considered as well, not simply ignored.
