Richard,
That is a valid point of view but it currently runs contrary to the Mayhem ethos of as little compulsion as possible.
Martin and the Moderators are currently thinking about it again.
I have to say that I have no objection to what you propose, personally, but I see the other point of view very clearly and it appears to be a majority view (that does not mean the majority is always right, of course!).
I have been giving thought to the controversy (in the British media today) about storing the DNA of unconvicted people who have been arrested but never charged or convicted. I guess many would say, "I have nothing to fear. Everyone should have their DNA stored". In relation to carrying Identity cards, the sentiment could be the same. However there are well informed and powerful arguments that run to the contrary.
Now, I am not putting Mayhem Profiles at the same degree of importance as the other issues I mention, I am simply saying, "To compel or not is seldom as simple as at first it appears".
