There was a time when policing was seen as a good job for a young Vogon. All those beefheads from the First XV's who failed the chop at the All Black trials had to find a more realistic career, and for most that brawn-to-brain ratio left them two main choices; the armed forces and the police.
A few years with the army could let a young Vogon travel the world on the public coin. The Singapore Rotation especially was sorely missed by the grunts when it was taken off their options. Since then, Waiouru cabin fever has set in. Unimog crashes, Linton light-ups, cowboy Iroquois flight paths, massive traffic jams to Ohakea air shows. You wouldn't want these people evacuating a public area during a natural disaster or anything. I don't think they'd be up to the logistical challenge.
Becoming a Police was the other option. You didn't need School Cert, and the training course was shorter than most hairdressing certificates. Once initiated into the ranks, you had protection. You were part of a brotherhood like no rugby team ever. Perjury, assault and battery; unless you were particularly careless, all these tools were at your disposal and the only people to judge you would be your brothers. Not the courts, and certainly not the public.
It was only a matter of time for this corruption and hubris to get out of control. And you can thank Helen Clark's Labour government for providing the catalyst. In 2007, the Serious Fraud Office was on death row and due to be replaced by a new Organised Crime Unit. These Supercops would be given unprecedented powers.
It has taken only five years for OFCANZ (as it it now called) to hang itself with its own rope. The police force, as we know it, has been shown to no longer be fit for purpose.
Falsifying documents, contempt of court, fraud, false oaths, deceiving the courts, lying by omission. Planting evidence.
The police are stuck in a power loop. Time for a complete reboot.
