There have been a few giant leaps made here!
Firstly, DungeonJayne and her example using the McCann child. If the police were to say �We want to search your house, and whilst inside we�ll take a few photographs which we�ll keep indefinitely� I most certainly would object.
Now the Reverend. The two �benefits� cited are highly unlikely to be realised. People holding multiple passports improperly will quickly find a way round the system. And to believe that bail jumpers will be detected at airports via fingerprints is fanciful in the extreme.
This post shows that the government is succeeding in its aim to get the population to believe that invasion of their privacy, usually by stealth, is acceptable. Their line is that the end always justifies the means.
So let�s consider this. Say the proposal to fingerprint all travellers is implemented. In a couple of years time along comes another � to take a DNA sample (and retain the profile) of all travellers. The usual justification (security) is cited and �after all, we already take your fingerprints, so it�s not so much more. Of course, if you�ve nothing to hide...�
Six months later another � to do the same on the London Underground. �Security, you know. Of course, if you�ve nothing to hide...�
A year or two later another proposal � to ask all travellers to turn up 12 hours before travelling. �All these checks we have to make take so long. Of course we�ll build a holding station for you to spend your time in whilst we make the checks, and once in, you won�t be able to leave. Of course, if you�ve nothing to hide...�
Fanciful? I think not. The frightening aspect of this is not the proposal, it�s the readiness of large numbers of people to accept such measures without question.
