When it comes to the powers of agencies such as the SIS and GCSB, some people believe that "the security of the state and of the individuals within it overrides other considerations", write Michael Cullen and Patsy Reddy in the foreword to their report Intelligence and Security in a Free Society.
Such a view, say the authors of the government-commissioned review, is aroused particularly during times of prominent international security threats, and "may be summed up in the often used phrase 'you have nothing to fear if you have nothing to hide'."
They continue: "For others, the opposite is true: freedom and liberty are so precious that any secret activity by state agencies must inevitably threaten those human rights, if only through the chilling effect of the fear of surveillance. Most people's views probably lie somewhere between these two extremes. Ours certainly do."
That is an uncontroversial statement, and a sensible place to start. But while the Cullen-Reddy report has its merits - the oversight regime proposed is an improvement - it is disappointing that the core balance they identify, between security and liberty, is hardly fleshed out at all.
The authors have much to say about security threats, albeit in mostly generalised terms, but the impacts of state-sanctioned surveillance on individuals and communities get scant examination.
