They say information is power. That was certainly the case yesterday as John Key deliberately dangled two disturbing pieces of intelligence agency - obtained information in front of those highly sceptical of the effectiveness, usefulness and overall value of the Government Communications Security Bureau.
The first nugget - that some people in New Zealand have links to overseas terrorist groups including helping to fund them - was not a huge revelation. There have been generalised references in the Security Intelligence Service's annual report to such being the case.
The second bit of information - that computer hackers had targeted New Zealand companies to obtain technical information that could be used in weapons of mass destruction - was the real headline grabber.
It is extremely rare for any prime minister to reveal even the tiniest fragment of the operations of the intelligence services.
However, Key clearly believed enough was enough and that it was time to impose a massive reality check on those arguing against a proposed law change which will legitimise the GCSB's illegal monitoring of New Zealand citizens or residents which was exposed by the Kim Dotcom case.
