Do public servants (ostensibly politicians and law enforcement) have any expectations of privacy while on duty? By definition the public ought to have the right to systematically surveille, monitor, and track their behavior - just as governments do their public, and corporations do their employees or equipment. It's fitting that the past decade has produced a neologism, "souveillance", to describe this approach. https://en.wikipedia.org/wiki/Sousveillance https://en.wikipedia.org/wiki/Sousveillance
