As I say, we've had widespread CCTV in shops in the UK since the 80s. In the last 30 years nothing has particularly changed.
I take your point, in theory an evil genius prime minister could install some mass surveillance system. But what the hell would be the point? And the chance of him not getting found out and called out by the media is negligable. Add to that the utter incompetence of government to do anything IT related, and I think we're pretty safe.
Your point is not academic... there is this new thing called WalMart, er, Asda. Ever hear about it? Cheap stuff for people with bad taste. Oh, and with a side of live-video-surveillance-with-active-facial-recognition feeding a worldwide db which has implicit (subpoena or court order... or not in cases of foreign nationals) access by the NSA / FBI / CIA. Um, and people are cool with it why? Because its all on VHS and has been going on since the 80's. I believe that is what you were saying...
