It may not matter who they are now: once their ID is cast into the DNA passport/ID Card data bank, they then become SOMEBODY for good. No more Montana trailer trash in Calgary hospitals. No more ex-pat Sri Lankan villages voting six times each in a federal election in a Toronto riding. No more 40,000,000 old age security pensions in a nation of 32,000,000 (sorry about that last example, a bit of artistic license.).
