A lot of people on this thread are judging the officer's actions with the benefit of hindsight. All the officer knew at the time was 65 in a 35 zone and total lack of cooperation. How was the officer to know that this was "just a speeding ticket" and not a DUI, escaping criminal, driving on suspended license, unreported stolen car, etc., etc.?
She stopped to start with, she provided the officer with her license and registration and she wasn’t verbally or physically abusive. I would not consider that a total lack of cooperation. She was clearly in the wrong. But she was in a situation that she was not trained to handle. That cannot be said for the officer.
