Spotting, I suppose you know that there is no such thing in UK as a "civil crime"? Or perhaps you don't...
Either it is either a civil offence or a crime, one or the other.
Also, being a free country there is NO law preventing "photographing people unaware" or virtually every photograph ever taken would be illegal, wouldn't it?
You're not really up on the most basic legal aspects, are you?
Gonna have to do a whole lot better than that for your second post!
