How will they change things? Why, is it official that they will be brought in? Why was I not informed? Well, since most ID theft rarely involves a face-to-face meeting, I shouldn't think that they will change things at all. And since, as far as I am aware, even if they are introduced, it won't be compulsory to carry them at all times, then the whole thing seems like a bit of a waste of time. I suppose it might catch a few illegal immigrants, but they tend to catch them if they are looking for them without much trouble anyway (the "fare-dogeres" hit is the favourite in Lewisham -- with policemen by the ticket-checkers. No-one is really looking for fare-dodgers. At Lewisham you are far more likely to catch someone with an outstanding warrant, not infrequently from the Ukraine).
