They are spending a lot of taxpayer's money on a 'voluntary' scheme, and this lot like to control and monitor everything.........
Well, they can't just turn around and ditch the whole thing (especially as cards are dished out to immigrants, wait for the racial harassment cases to appear soon) because then they would have to explain why so much money was wasted on ID cards and the "database". Best leave it to those who are from another country and those who, although blind but can see perfectly, decide it's a jolly good idea to have such a thing or be on the "database" to prop the scheme up as "gentle persuasion" gets used to edge the total numbers of cards upwards until they think they can force everyone to have one. Of course, they know that when they lose the next election then the chance of such a scheme would be over. And someone else has to spend a fortune sorting out the mess (Can't be us wasting all these billions dismantling the scam, we ain't in power any more, guv).
