i still don't see what the big problem is. if you're in public, you're in public
Being watched by a security technician through a CCTV camera while I walk along the street doesn't bother me more than being watched by pedestrians, drivers and other people who're physically present in the area (which, incidentally, does bother me, and I prefer it when nobody else is around).
What I see as 'The Big Problem' is that with increasingly sophisticated and integrated surveillance systems, we'll soon reach a point where anyone with the right security clearance, or anyone who finds one of those laptops or flash drives with unencrypted national databases that civil servants keep leaving in taxis, trains and buses, will be able to run a query on a person and be informed of the places they've been, when they were there, who they've associated with, what websites they've visited, what search terms they've typed into Google, what they've spent their money on and so on.
It'll be like having a private investigator on steroids following us around wherever we go, and the information won't be made publicly available, where it might expose all the crap that politicians and government officials get up to and usher in a new era of honesty and openness. It'll be available to authoritarian bureaucrats who obsess over who's putting too much in their wheelie bin, creepy stalkers who hold government jobs and want fuck up the lives of their ex's, politicians who're trying to win votes with the latest paedophile/drugs/terrorism witchhunt and criminal organisations that purchased a laptop or flash drive from a homeless guy who found it on the seat of a bus.
