Hardly anybody in this country's heard of the GCSB. Key can get up and give them a verbal hiding for incompetence, and people will think "Gosh, these GCSB clowns sound like a real pack of idiots, good job the PM's onto it" and think no further on it. The PM's problem nicely sorted by drawing attention away from the actual issue at hand.
Which is, as very well laid out in this post by Graeme Edgeler, the role of the New Zealand Police in all this. Heard the PM mention their involvement and the conclusions we can draw from it? No, and don't expect to either. Edgeler sums up:
The actions of the Police in using the GCSB as an end-run around laws we have put in place deliberately limiting police powers are of much greater concern.
This looks exactly like the Police asked the GCSB to intercept Dotcom's communications because NZ law prevented them doing it themselves, which would be of concern all on its own. However, the Police (in the form of OFCANZ) also falsely assured GCSB that the people to be spied on weren't NZ citizens or residents, and later also falsely assured a New Zealand court that they hadn't involved any other agencies.
That is a steaming pile of very serious shit, and next to it the fact that GCSB took the cops' word for it about Dotcom not being a permanent resident is almost inconsequential. Let's see some journos or oppo politicians putting Tolley's feet to the fire over this. Coming after the Urewera "terrorist" fiasco this makes our cops look corrupt and incompetent.
