I'm pro-police too Pixc. Yes they do have a job to do and some of them do it very well. No that job is not hindering the passage of law-abiding citizens who just happen to have long hair and drive old cars.
I believe that the amalgamation of the old Traffic Department with the New Zealand Police was a huge step backwards in that it cost the real police a lot of public respect. In the past it was obvious which was which and honest law-abiding citizens could proceed about their business unhindered. Now it is difficult to tell the difference and there is a widespread perception that the police are wasting too much time on traffic duty while real crimes go un-solved.
