Nothing to hide, nothing to fear?

The authoritarians always like to claim that if you have nothing to hide you have nothign to fear. Well when 1500 people assembled on the banks of the River Tyne who where hiding absolutely nothing as part of a work of art by American artist Spencer Tunick they probably thought that they had nothing to fear either. They where wrong. Mr Tunick wasn't the only person with a camera focused at them, there was also the operators of the local CCTV system. Who zoomed in on individuals, and then tried to sell the naked photos at their local pub.
