How To Catch A Liar

Joe McKinney is a homicide detective for the the San Antonio Police Department.
He also writes horror, crime, sci fi and articles like the following I recently discovered "In Cold Blog."
Joe's article sprang from a seminar he attended that featured Mark McClish... a former Deputy US Marshal wth 26 years under his belt.
Mark is an instructor at the US Marhshal's Training Service... and  an expert in interviewing people and detecting deception....AKA lies.
Joe interviewed Mark and the end result is this article and link... a must read for those like me who are paid to help separate fact from fic
