There are eighty years of history still fresh in people's minds. I think that is the biggest difference.

My mother thought that it was fun to look at her house on Google Streetview - for about five minutes. Then she came to the realisation that if she could see everything, so could anyone else using the internet.

That is why we need a TSA equivalent of 'naked man climbs into the trunk of his car whilst dog stands by, unperturbed'. Naked man did a lot to raise the awareness of privacy issues in Germany, and one day soon I am convinced that one of the passengers in the US will become the equivalent to the US public.
