Personally I don't think people shoud have to hand over ID to prove who they are for everyday normal activities like going for a drink.
This has come up at work. Places now demanding ID to deliver something. Company ID not always being enough.
Like workmate said to me yesterday the rich do what they want and we have to justify ourselves to Them. Why don't they just leave us alone.
There is general feeling that the little peoples lives are more policed than before. Yet life has not got better or more secure.
Some of this is driven by technology. Its now possible to have scanning machines or facial recognition CCTV so it just gets used.
Common reason give is its Police advice to bring in more "security". Especially in big buildings.
So gradually its becoming , without it agreed by law or with public debate, that carrying ID is essential. And not just any ID.
David Davis recently said this about the latest technological "advance" in security.
