Speeding ticket question
My wife got a speeding ticket while traveling east bound on Rt 22 in Harrison county, OH. The speed limit on this highway is 55mph in some areas and 65mph in others. She swears she was in a 65mph zone with her cruise control set at 65mph on the nose. An officer traveling west bound apparently clocked her going 69mph, made a U-turn and pulled her over. She said he was very abrupt, said he clocked her going 70mph and then 69mph so he's going to write her a ticket. She thought he was an A-hole for writing her a ticket for going 4mph over, and also she had her cruise set at 65mph, but that's another topic. Not until she got home and looked at the ticket did she realize he wrote her up as going 69mph in a 55mph zone. She was really ticked off then because she knew for sure she wasn't yet in the 55mph zone but still in the 65mph zone. I was hoping the officer would have written down exactly where he gave her the ticket but he didn't, he simply wrote that is was on US 22 EB, no details on the exact location.
My question is should the officer have written down exactly - or at least some detail - on the location she was pulled over? All we have to go off of is that she was pulled over on Rt 22 in Harrison county, which has spots of both 55 & 65mph. If we can't prove where she was pulled over I'm afraid we don't have much of a case for argument. Any thoughts?
