Going east bound apprx 5 miles west of Forest State Trooper like to sit at the bottom of a hill. I was doing 70 and got up to 72 while going downhill. Other cars were passing me. He stated I was doing 81. I asked to see his radar screen where he locked in my speed but was denied. Went to fight it but Lawyers charge $500 per hours for traffic offenses in Forest, MS. I travel to TX several times a year and he is always present in the afterrnons.
