@BillRM,
Thanks... Simple logic, no?
Any staff working in the heart of the NSA can:
- start a profitable blackmailing business
- steal and sell industrial and commercial secrets
- make billions on the stock market by getting privy info on deals (an insider trader's paradise; i'd be surprised if some smart ass hadn't done so already)
- break up marriages / couples by prying on affairs
- dig up dirt on political candidates and thus weigh in on elections...
Should I go on?
So yes, information is precious; it has a value, including a commercial worth, a great deal of which is lost when many other people get to know the same info. That's one reason for an expectation of privacy, eg on behalf of private firms and citizens. They are many others, such as the right to privacy in health, sexual and amourous matters, the right to not publish one's private thoughts or a dairy, etc. For the state, there is a justification of secrecy for national security, eg when at war, but also more broadly for reasons of division of powers, as well as for tactical, short-term secrecy in negotiations, disputes, etc. Diplomacy has an expectation of secrecy because of this, like poker.
Either you respect that principle or you don't. But why accept it for governments and refuse it to citizens and companies?
