I know Solo - and it all starts so innocuously.
The concerns people have around broadening of both surveillance and the broadening acceptance of it (as seen in this thread), has nothing to with having anything to hide, and everything to do with how that surveillance can be misused or misinterpreted.
As an example, lets say Lard or kermit or Polo crosses an empty street, with clear visibility in both directions, in the middle of two crossings, 100 metres each away in Austria. This is picked up on CCTV, facial recognition employed, your address located and a fine automatically issued. You've created no risk, caused no disruption but broken the law - so you pay for it - I assume you'd have no issue with that?
Or, you are in Austria on hols, in the city and close to the street where the 'crime' happened, but the facial recognition system makes an error in identifying you and the CCTV doesn't entirely zoom in, but that plus facial recognition is considered sufficient proof it was you. So, there's no independent witnesses, or police who asked for ID of the person they caught jaywalking so, how can you prove otherwise? Would you have an issue with that?
The examples above are just small ones of how easy it is for someone with "nothing to hide" to become a criminal when there's no right to reply or when surveillance picks up a mistake that breaks the law, but doesn't harm anyone or anything (i.e. jaywalking's not a crime in the UK, so you didn't think about law-breaking when crossing that Austrian street.)
