We hear this nonsense about the only people who’re concerned about privacy are people with something to hide. Well, yes. How about your password? How about your pin? How about various aspects of your physical person? How about various aspects of your health? Various aspects of your finances? The fact that you’ve got a really really valuable painting in a house that is really easy to break into and that doesn’t have a security system? How about the way your kids go to and from school? What your daughter drinks, and which drink to spike? There’s any number of things that people have to hide.
The Jews who lived in Holland in 1939 had nothing to fear from a database that identified them as being Jews. Well they don’t have anything to fear now ‘cause they’re all dead, with very few exceptions. The people who had reasonable educational qualifications in Cambodia in the 70s had nothing to fear. What’s there to fear about knowing that you’ve got a certificate of an advanced diploma? Well most of them are dead too. In Rwanda/Burundi it was being thought to be of a particular ethnic background. Now it’s not terribly easy for people to tell ethnic backgrounds when they’re tribal and they’re adjacent and they’ve been adjacent for hundreds and even thousands of years. But the decision was made that you were of that ethnic persuasion therefore you were dead. Now these are just the sharp end, where the worst case of invasion of privacy occurs and you get killed. There’s lots and lots of circumstances where obscure bits of information do harm the people that somewhat less than killing them.
