I had a similar experience as above when I was in college. I went out to a bar around 9:00pm to meet some friends and listen to a band. I was not drinking that evening and was asked by one friend to drive him to his house as his car would not start. By this time it was a little past midnight at this well known late night honkey-tonk on the edge of town. When we pulled out of the parking lot we noticed a state trooper parked facing the highway on the opposite side of the road. He pulled out behind me and followed a short distance behind. My friend and I joked about the trooper missing a DUI collar since it was obvious he was waiting for an intoxicated customer to depart from the bar, and usually at this time of night, any car would be a target. After following us about one half mile he lit me up. He asked the usual questions about how many drinks did I have?, did you know you were swerving from lane to lane?, etc.. He obviously was miffed when I said I was actually being a DD for my friend, have not been drinking, and easily passed the FST. Not satisfied, he brought me into the local cop shop for a breathalyzer test....which I passed 3 consecutive times. He gave me a bogus ticket for improper lane usage and said I was lucky I didn't get a wreckless and careless! He would not give me a ride back to my vehicle and I had to make other arrangements (this was back in the early '80's, pre cell phone...so a major hassle). The thing is, I saw him when I entered the highway and was darned sure to exhibit my best driving behavior since I knew he was looking for drunk drivers (in a target rich environment). I wish there was dashcam back then because I would have gone to court on that one so that would have been presented as evidence. What the nice officer did not know was that I knew several of the local PD that were present and told me, once the trooper departed, that he was a known A-hole and that the judge is aware of it also. I did contact the judge who said he would handle it if I sent his clerk the citation; I did and he did. I, a bit later in life, had the state police superintendent as a patient with whom I had developed a very good relationship. I related my story from my youth and he actually remembered the officer well and stated he did not last but a few years and was discharged. The superintendent, then just retired, gave me his card and said while still on the job he was limited on favors he could grant but now, since retired, he could pull many more strings. He said, "If you get in any legal bind having to do with the police, I will be very upset if my number is not the first one called; I have connections you could not imagine". I still have his card as a memento although he is long deceased. I'm glad I never had to use it.
