Is the minister really saying that a member of Parliament should not be allowed to point out that public confidence in the police can only suffer if the police are seen to refuse to recognise that such a serious breach of acceptable standards has been committed? Is the minister really happy to leave the matter as it stands - and as represented by Mike Bush's assertion?
However inappropriate it may be in this instance, it is of course commendable in principle that the minister should defend her public servants; but her response is in marked contrast to the attitude increasingly taken by ministers in this Government. It is now common practice, when things go wrong, for ministers - not to defend their officials, but to blame them - as a means of avoiding any responsibility themselves.
The most recent and egregious example is the outfall from the Novopay debacle. A process that has created huge damage to an important public sector undertaking - our schools - was monitored and eventually signed off by three ministers; when they put their signatures to the sign-off, they in effect accepted responsibility for what they had decided.
We are now told that they did not know what they were signing because they had been provided with inaccurate information by their officials. The consequence is that the senior officials involved have been hung out to dry; two have departed (the second under threat of an investigation) and the pressure is mounting against the third.
The ministers sail on unchallenged and unaffected. It was not, it seems, anything to do with them. In this, they are following an unfortunate precedent set - among others - by Murray McCully.
Just over a year ago, the Ministry of Foreign Affairs and Trade was to undergo a huge shake-up. The numbers of posts and of diplomats were to be slashed; appointments of ambassadors were to be made following advertisements for applicants.
When these plans were eventually abandoned, or at least substantially curtailed, the minister declared that they were nothing to do with him. According to Murray McCully, MFAT's chief executive, John Allen, was to blame and should carry the can. The minister was, he assured Morning Report in March last year, merely "the purchaser of services" from the ministry.
This novel doctrine is, of course, in marked contrast to the keenness of his ministerial colleague to make common cause with the public servants who work for her in the police. It also raises an interesting difference in approach from that taken by another minister - the Attorney-General, Chris Finlayson.
The Attorney-General, we learn, is upset by a Supreme Court decision that advice from a civil servant to a minister is not protected by parliamentary privilege - indeed, he is so upset that he intends to legislate to make it clear that a civil servant and a minister are joined at the hip and must both be protected.
The Herald takes the same view. That view could be argued to represent a significant extension of parliamentary privilege (as the Supreme Court decided). But, in any case, if civil servants are so integral a part of parliamentary process that they and their ministers are in effect one and the same, shouldn't they be less easily thrown to the wolves when it suits the Government?
