Speed drops from 65 to 45 mph and never saw cop car, was reducing my speed when lights appeared. Did not have a chance to slow before pulled over unless I hit breaks hard. Pulled over in view of next 65 speed limit sign. Set up to have motorist fail. High percentage of town income from fines. Checked stats. Population 200. 10 miles south of I-20. Other traffic same speed, my out of state plates a target.
