I agree, however he should ave said exactly that. He should have said that he is not able to tell her. Not that he refused to tell her. There is a difference.
I think she acted like an ass. I certainly would not act that way. However, one better worded sentence and the entire matter is resolved quicker and without her getting her temper up.
But just because the incident report is a public record, it doesn't mean the police officer is obligated to speak to any uninvolved person on the side of the road about the motor vehicle stop. In fact, he even tells the woman she can pick up a copy of the incident report on the following Monday.
And Caren Turner is an attorney, which means she already knows all of this.
Not only did this police officer do the right thing ... it looks like he played it perfectly.
