It's a dilemma isn't it?
We like our privacy, but when I got mugged in a subway in Birmingham at 3am and left unconscious in the cold in the middle of winter without a coat ('cos he took that) it was rather useful that it was all seen on CCTV and so they sent an ambulance to pick me up and take me to hospital where I woke up many hours later. Without that CCTV I could have died out there.
I think the unfortunate thing with these proposals is that they are un-enforceable and so rather pointless. We have to accept that CCTV is a fact of life now, we can't un-invent it and we're extremely unlikely to ban it. So we really ought to be providing a suitable statutory regulatory framework with teeth. But the politicians have no vested interest in that happening so it won't.
Beer 'cos it's Friday.
