Level of enforcement is unknown by me. Type of enforcement is also unknown by me and is not indicated on the ticket. The Officer observed me enter into the town city limits of Tupelo. Observed me slow my vehicle to the posted speed limits. The first speed zone was 45mph and the second speed zone posted very close was 35mph. By the time I reached the 35mph speed zone I was traveling at 33mph. The officers vehicle was headed in the opposite direction and stopped on the side of the road. As soon as I passed him, he made a U-turn and started pulling up behind me. Of course, I was watching my rear view mirrow and very well might have missed the blinking (if it was) light indicating a School Zone. At no time did I accelerate my vehicle until I started up the hill going out of town at which time he turned on his emergency light. This is a very small rural town. I am charged with doing 46mph in a 25mph School Zone and the City Fine is $200.00. After going back through Tupelo and looking the area over real good, there is no way I was traveling at 46mph. I might possibly have been going 30mph. I spoke with a city employee who related the Mayor was please the town had not made the Speed Trap list this year. I personally believe persons from other areas passing through this town are selected to be ticketed (rightly or wrongly).
