As a lot of other things, it happened step by step, with the main catalyst being 9/11. We somehow accepted that it's an acceptable trade-off to have no privacy in the name of stopping "the terrorists". "You're either with us, or a terrorist" Bush once said. And now we're at a stage where it's acceptable to say things like "if you've got nothing to hide, why are you so worried about this stuff?".
