He pretty much caused every wrong in this incident minus the woman not using her turn signal. he asks her why she is irritated... he already knew why.
...
And possibly her behavior was due to being impaired. He would have a duty to investigate that.
Actually, she explained to him why she was irritated.
He was playing "cop games". She said that he was behind her and sped up [reviewing the video, this is true. He also spun a U-turn quickly in an intersection, which may or may not have been legal in that situation.], so she attempted to get out of his way by changing lanes.
So then, he was able to "tag" her with no lane change signal. I had a policeman do the same thing to me once.
Once I realized that they get PAID to sit on peoples' bumpers and see if they can cause a reaction, I changed my tactics. Now, I just sit tight and hope they don't get an itch to pull me over.
He directed the thing from start to finish.
