One of the benefits of practicing in York, Pennsylvania, is that the local newspaper, the York Daily Record, employs Dylan Segelbaum. His reporting on issues of crime and the courts is really excellent. A while back, he reached out to a number of people to dig into a claiming indicator of drugged driving: the infamous "green tongue." The result was this really excellent and well-researched article. There is video, too, and I get some facetime in it. It is definitely worth the time to read it.
