But if it became clear to everyone's astonishment that a Conservative government were not going to abolish ID cards, or if the Labour party won the election and we had another parliament of developing ID cards – possibly to the point where they couldn't in practice be abolished by anybody – then external critics who concentrated only on the abolition of ID cards would be rather wasting their time.
Don't these words from Sir John Pilling, the ID card commissioner strike you as slightly chilling?
Couldn't in practice be abolished? Doesn't he undestand that in a democracy no government can bind a future government. That decisions can be rescinded? Or is he right and when something is enacted it becomes a Horatian bridge?
