I've known one of those people that watch those cameras and I'd struggle to call him a pervert. He's was just normal guy who paid his bills by doing an incredibly dull job. All it came down to was making sure that when petty shit happens in the street (drunken fights, etc), the police and so on are called to the scene.
I'm usually someone that's very fond of privacy, but I'm not entirely sure I have any qualms with CCTV in public places and in fact I'd love to hear arguments against them.
