My understanding is that if this goes to trial, they will amend the speed back up to the original radar reading in his notes.
So what is the best strategy, request trial, request disclosure, and go to court and hope that prosecutor offers a reduced charge (reduced from 20 over not 38 over), because if it does go to trial and they amend it up and it's me vs officer, I have no chance right ?
So you should plead NOT GUILTY and ask for Trial with Officer present. Once you get notice of trial then ask for disclosure (officers notes, speed measuring device manual, audio/video).
Once you get disclosure you can then decide if there is a way to beat the ticket or not and then decide to just pay the 20 over or try to beat the 38 over.
But you should always take advantage of reviewing the disclosure before you decide what to do.
