Indeed "totalitarian state controlled by a political police force" is not the thing - Brit here. Iran maybe.

I didn't use the word "totalitarian", which the UK still isn't for the time being. A surveillance state doesn't necessary have to be totalitarian (the CCTVs were in good conscience put there to protect us from the baddies). But it certainly is a precondition to become that over time.

Almost 15 years, yes. Were you born in the UK, or do you have outside perspective?

Not GP but I was born in the UK, and from 'CCTV on every corner' even as an exaggeration I'd question if you stepped outside London in those 15 years, not counting 'London' airports.
