Professor Imwinkelried Interviewed on Expert Testimony and Scientific Evidence
On August 8, Professor Edward Imwinkelried was interviewed by Roger Kingkade on radio station CHQR of Calgary, Canada. The topic of the interview was the Department of Justice Office of Inspector General's July 2014 report about flawed expert testimony on hair and fiber analysis by FBI Laboratory analysts.
Professor Imwinkelried explained that the report had found that in many cases, the analysts had overstated the inferences that could be drawn from their analyses. For example, analysts had improperly claimed that they could definitely determine that an accused was the source of a hair strand found at a crime scene. He pointed out that more broadly, the 2009 National Research Council report on forensic science concluded that in the past, experts in many forensic disciplines had succumbed to the temptation to exaggerate the inferences that could legitimately be drawn from their test data.
Professor Imwinkelried is a world-renowned evidence scholar and has published extensively in the field. He is the author of The Methods of Attacking Scientific Evidence.
