The announcement that police would not charge freelance cameraman Bradley Ambrose over the so-called "teapot tapes" affair should have been both a victory for the man himself and an end of the matter. It was neither.
Assistant Commissioner Malcolm Burgess said police would issue Ambrose with a warning "but we are clear that [his] actions ... were unlawful". But such a declaration is not for the police to make in a democratic society: the police allege illegality; a court, after following due process, decides whether the allegation has substance.
Likewise, the Prime Minister, who laid the original complaint against Ambrose, was quite wrong to tell police that he "did not believe a prosecution was now necessary". He said this after Ambrose wrote a letter to him and Act MP John Banks expressing his "regret for how this matter has unfolded" but conspicuously not apologising for the recording of the conversation, which he has always maintained was inadvertent.
It is, quite properly, standard practice for police to seek the views of victims of alleged crimes before deciding whether to proceed with prosecutions. But this matter had become so highly charged - and its implications for relationships between the media and the executive so broad - that the PM should have told police it was entirely their decision. To do otherwise created the undesirable impression of collusion between police and politicians.
The PM's behaviour in this matter has been questionable throughout. He and his lieutenant Steven Joyce were quick to compare this newspaper to the News of the World, whose staff hacked the cellphone of a murdered schoolgirl with the connivance of managers who now face criminal charges. He said he sought to save us all from falling down "a slippery slope".
