BM] Your example of driving in New Zealand illustrates my point. Of course there is a practical advantage to carrying your driving license whilst driving. This practical advantage is that if stopped by the Police, you would nat have to go through the painful process that may arise from your not carrying it. This is my point with ID cards - one might carry it purely for teh "practical" reason that it is law and it is easier just to obey the lwa and thereby avoid any ridiculous consequences that may arise from not carrying it. But there is no MORAL reason why one should carry an ID card. I think what you fail to realise is that although our moral obligations often comply with legal obligations, many people do not believe that something is a moral obligation simply because it is a legal obligation. This is especially true when it comes to minor traffic violations. I must say that I find your blind obedience quite frightening, in a 1984 kind of way.

StD] I know this is an argument where no-one will convince anyone else, but I have a problem with individuals deciding what they are and are not morally obliged to do. I'm sure Harold Shipman believed that he was morally right in relieving these old people of their suffering (and I know that's a reductio ad absurdum, but it is the other end of the same continuum). As for minor traffic offences, the roads are provided and maintained by highway authorities/the government for people to use in cars under certain conditions. Thus I would equate asking people to carry their licence with insisting that cars should be taxed and insisting on speed limits with insisting on insurance or insisting that people should not be under the influence.
On identity cards I would take the French view, that they should be provided cheaply and for all, but that it should not be obligatory to carry one (most French people do, but that's for convenience). However, the government shouldn't argue that they will be good for the country and for security and then try to recoup the entire cost of providing them in their cost.

[INJ] Individuals do make their own moral decisions, Shipman included. If you're suggesting a moral principle that laws ought to be obeyed, that's your principle and you're welcome to live by it, but it's still up to everyone else whether they decide to adopt that principle or not.

[INJ] "Cheap" identity cards? Whatever the upfront fee, the entire cost of introducing cards will be borne by the taxpayers. That is where governments get their money from.

[INJ] The only real problem with insisting individuals align their morals with the law is how you go about enforcing it. After all, surely that's what the law is intended to do anyway! When it comes down to it, I don't think it's possible to force someone to adopt a belief - and what are moral values if not beliefs?

[Raak] At the risk of hounding you from server to server on the topic of redistribution, they do, but not equally. :) [Darren] I think I'm happy with the law as a means of controlling behaviour more than belief. It then isn't necessary to believe wholly in the moral force of the law, but to simply act expediently or calculatedly in relation to it. If the law is any good (and sometimes it is very good), its drafters will tend to make some rough calculations about the behaviours it will provoke and try to ensure those give the moral outcome desired.

[Raak, Darren] You're right of course, and I think I've said something that I don't really mean. I suppose I have misgivings that people (including myself), have a tendency to advance a 'moral high ground' defence for something that is really much more to do with convenience. This weakens the force of real, more important, moral stands.
[Cost of ID cards] If there are advantages in things like security, reducing benefit fraud and the like, then the cost of ID cards should be at least partly borne by those budgets. If you don't do that then in effect it's an addition to the government tax take - I'm arguing that it should be neutral or that the cost should come out of general, means-based, progressive taxation..
