One officer with radar parked in shopping center parking lot in an area of the Main drag having 4 lanes. He radios ahead to a waiting officer, who pulls out behind you. Second officer claims to have locked you on radar at an excessive speed, when it was the first officer. I was clocked 13 miles over the limit by the first officer, parked on the left side of the highway, while I was trying to pass 4 motorcycles who were travelling in the inside lane. I was in the outside lane. The officer targeted me on radar somehow with them between me and the radar gun. By the time I reached the second officer, I had concluded that the first officer was not going to pursue and I had slowed down under the speed limit. I admit I was over the limit, but not by 13 mph. My speedometer showed me at 52 in a 45 mile zone.
