What's the right balance between social cohesion and personal freedoms where society can continue to exist whilst each individual is able to enjoy the freedoms they're entitled to ?
What people have forgotten to consider is : can a completely anonymous society continue to exist as a society ?
Social cohesion has always depended on a degree of control of the individual by the group. That, naturally, caused a lot of pain to anyone who stepped out of line. When people started to migrate to cities, their privacy increased. Hell, to this day gays will move to the city in order to escape the intolerance felt back in the small town they come from.
While privacy increases, social cohesion decreases and unsurprisingly this gets abused by criminals etc who benefit from the increased anonymity.
Now with the ability of the common citizen to view the cameras, we're seeing the return of the control of the individual by the group.
I'd like to argue that this could in fact be a GOOD THING. People won't be watching out for if you're gay or foreign or an unmarried couple but will be watching out to see if they can catch you red-handed committing crimes. In a way, the fact they don't know you but are watching out for the crime removes the prejudiced attitudes and only leaves the question of : is this guy in the picture breaking into that car or not ?
This could actually be the solution to a major social problem.
