Dear New Zealand Police,

This request is made in accordance with Roading Police use of a Radar unit and contextual evidence relied upon in court proceedings:

1. Please provide a copy of the Road Policing manual;

* Police Policy for collecting evidence using a radar unit;

* Operation instructions use; and

* What is required for evidence to be reliable that supports context?

2. What are the pitfalls of use of equipment in certain weather conditions? And

* What conditions are not suitable to for use?

3. What will cause the readout to jump and give a non-consistent speed?

4. Can conditions prevent the radar from picking up the target and send back an accurate reading?

5. For a reading to be demeaned accurate does the speed on the readout unit need to be consistent, and

* Does the tone need to be constant and unwavering?

* What happens if the Dopler tone is inconsistent?

6. Is the unit adjusted for weather conditions? And;

* What adjustments can be made to the sensitivity of the unit reading at the low and high end?

* What is the main use of this function?

* What occurs when the unit sensitivity is turned down?

7. To give evidence contexts must any photographs of alleged speed be accompanied with the officer’s notebook with the traffic stop recorded? And/or;

* A photograph of the readout with the vehicle in the background for context and evidential value?

* Can you use photograph as evidence if there is no date, time, defendant or vehicle in the photograph to tie the alleged speed to the event, (i.e. evidence without context to the event)?

Yours faithfully,

Lee
