Of course, the democratic control needs to be exercised and the current Labour government doesn't command enough trust for me to actually want them to have my data - and this is both on authoritarian instinct and on technical incompetence. When the capital development of a country becomes a by-product of the activities of a casino, the job is likely to be ill-done. — John M. Keynes
I don't feel uncomfortable about the state having my data, in fact i feel it would be more worrying to think that the state didn't have my data. (although strangely comforting that they probably cant find it when they need it) A trely technicallly competent government would be a scary thing to behold. Any idiot can face a crisis - it's day to day living that wears you out.
The best control is not give the state data, such as fingerprints, as a matter of course. To limit the state's capacity to exercise its monopoly.
