I guess I'm looking at it from an angle, ok.....fingerprints now but what next? Where do they draw the line?
The answer to that is: they don't and won't draw a line (and you know it, but many others in here certainly do not). They already tried to be even more radical with this by requiring the same from every immigrant, no matter the country of origin (and got shot down, good work by the privacy groups there). After a while, once they would have seen that this fingerprint database doesn't really help at all (increasing surveillance does not deter crime, the UK and their extensive CCTV network should have already shown that), they would have demanded something more on the same flimsy just-in-case basis.
This brings me to the main point: what is it exactly that warrants all this paranoia against immigrants, that all of them should be fingerprinted? As far as I know, in the countries with the largest legal immigrant populations, they commit far less crimes than the "native" citizens! Take USA, for example: nation-wide immigrants are five times less likely to be in prison than the main population. In California, the state with the largest immigrant population, that factor is 11. This law proposal is nothing but some baseless fear-mongering, maybe by some nationalist politicians and groups.

The patterns with any privacy-reducing laws and other sorts of restrictions have been extremely clear: they'll want to fuck people's privacy up as much as they can. And they will, if they learn to do it subtly and covertly enough. So far all these recent attempts in such lawmaking have been too radical and that's why they have gotten this sort of backlash.
Another interesting thing that I think is pretty accurate: if you store a large amount of data for a long period of time, the higher will be the probability for misusing it. Unwarranted just-in-case databases of personal information should not be allowed. Someone with malicious intent will always be able to get access given enough time and in those cases some measures should be in place of controlling the damage. A fingerprint is a permanent immutable record of a person, as far as I know and that's why it should not be just collected just whenever some privacy-bashing politicians decide to get an erection.
