Its great to know that university people are looking to improve imaging for impression evidence. This time its shoe prints. Too bad the experimenter thinks that “gait” leads to a “somewhat distinctive” pattern which then begs the question about false positive results or exaggeration. I still remember the shoes OJ owned were “somewhat distinctive.” And “they fit.” (this last is from the FBI expert in 1997).
