The Trooper clearly states that he obtained the speed from his rear antenna, but also states that I was in front of him. He also states that he had the speed reading for at least 15 seconds. I am not sure if that is required or not, but it is not even 15 seconds from the point I started to accelerate to the 55 mph sign, so he could not have possibly has me on his radar in the 45 zone for 15 second. I have also noticed that there is an argument to made for not clearly stating the subsection of 46.61.400, should I open with this, or the fact that he states that he used his rear antenna and I was in front of him.
