About Statement Analyzer
Welcome to the Statement Analysis® website. My name is Mark McClish. I am a retired Supervisory Deputy United States Marshal with 26 years of federal law enforcement experience. I taught interviewing techniques at the U.S. Marshals Service Training Academy which is located at the Federal Law Enforcement Training Center in Glynco, Georgia. During my nine years teaching at the Training Academy, I conducted research on deceptive language. Based on my findings, I developed techniques to determine if a person is lying or telling the truth by analyzing the subject's language. I call my method for examining a person's words Statement Analysis. Statement Analysis® is the most accurate way of determining if a person is lying in a verbal or written statement. A person cannot give a lengthy deceptive statement without revealing that it is a lie. This is because people's words will betray them. There are usually several ways you can phrase a statement.
