There are some things you do in your career that you'd rather not have done. Mine was infiltrating a southern motorcycle gang more than 40 years ago and riding to the Alexandra Blossom Festival which you'd think would be a most unlikely place for gangs to assemble, but that they did from all over the country.
The gangs had complained they'd the previous year been roughed up by the police who weren't wearing their identification numbers, which of course they're required to do by law.
Riding through the countryside with around a hundred thundering bikes certainly gave you a feeling of power, but that feeling turned to disgust at what they got up to when several hundred of them set up camp at an area on the outskirts of the Central Otago town called The Pines.
In those days though, drugs weren't the problem that they are today.
Not too many years later the then Prime Minister Rob Muldoon had gang members up to his office to try and steer them away from crime and into work and laid down the law to them about showing more respect for their women and children. He became the patron of Black Power who performed a rousing haka at his funeral in 1992.
