The SFST Conspiracy Theory

This is an interesting theory that I just heard about.  There was a woman with a PhD in Psychology named Dr. Marcelline Burns, who developed a theory in the 1970s that someone's alcohol level could be determined by making them do a few tests, like have them follow a flashlight with their eyes or walk a few steps along an invisible line.  Every police department in the country follows this theory, but it may be totally fraudulent, or at least junk science.  There is a lot more to say, but for now just google the name "Marcelline Burns".
