I was nabbed in Port Hope, but this should apply to other areas too. The defendant in this case was totally unprepared, so he didn't even mount a real defence (and in fact his own witness said that he was speeding). The useful info was in the air officer's testimony:
- the timing device is the Robic Sport SC-888, he mentioned the time of testing (before and after shift) but not the procedure
- hash marks are placed at 500m apart, and the officer testified that he was present at the time of painting and has personally measured each "quadrant" to be exactly 500m and tested this measurement with odometer and radar
- opening testimony was standard fare -- "I observed vehicle at high rate of speed and then confirmed by... "
- testified that he always had a clear and unobstructed view of the target vehicle and never took his eyes off unitl the ground stop was made
- gave testimony about the distance between the last hash mark and the stop (presumably to say that it was a short time between the offence and the stop)
- indicated that he did not know model of car until ground officer made the stop
- flies at about 3000-4000 feet
- said weather was clear and visibility was greater than 20 nautical miles
- testified about his training history on radar (NOT used in this stop)
Hope this helps!
