So a man wanted to play police officer and pull people over on the road. Well he pulled over the wrong car. It was an unmarked car that contained two highway patrol officers. https://amp.usatoday.com/amp/786758002 Some people want to play dress up and act like police. Maybe they like imposing authority onto other people, a psychological component to their personality (one that many who in fact choose to enter law enforcement possess). Or maybe it fulfills some fantasy. I don't think this man had any ill intentions, but there have been cases of men impersonating police officers to rape women. Just goes to show when someone approaches you who looks like police, you can't always be completely sure.
