There's a reason I started my presentation by talking about privacy as a human right.
The fundamental duty of government is to safeguard and protect the human rights of its people, and that includes providing security, of course, and it includes guaranteeing freedom of expression, but it also means respecting their privacy. Going back to the Information Commissioner's recommendation, I do think that the discussion of privacy impact assessments and mandating those is a good step along that path. That should always be a concern when you have legislation or policies that are affecting privacy. The rights aspect should be central to considerations.
