This is only my opinion, but I'd like to see a picture I.D. card carried by us all in the UK containing the easily available information about the individual, including DNA plus medical records updated at your GP or Hospital; for one thing we could leave the passport at home when nipping off to Europe for a break plus help the emergency services give quicker help.
Whats the big deal so long as you are a UK citizen and doing no harm?
I share your view on this - If you're not doing anything wrong then what's your problem???
A DNA data base would be on my list too. It would solve alot of crime in one fell swoop.
