Advanced Interviewing Concepts Detecting Deception Using Statement Analysis Welcome to the Statement Analysis website. My name is Mark McClish and I have been in federal law enforcement for 24 years. From 1991 - 1999, I taught interviewing techniques to federal law enforcement officers at the Federal Law Enforcement Training Center (FLETC) in Glynco, Georgia. During my nine years at the FLETC, I conducted my own research on how people respond to certain questions. I studied hundreds of statements and found that people will lie in the same ways. Likewise, people will tell the truth in a similar fashion. I call my method for examining a person's words "Statement Analysis." Through Statement Analysis you can determine if a person is being truthful or deceptive. You can also obtain additional information from a person's statement. This is possible because what a person does not want to tell you will influence what he tells you. People's words will betray them. Even though they may want to withhold information people will give us more information than what they realize. Unfortunately, they sometimes give us more information than what we realize. The key is to listen to what people are telling you and to know what to look for in a statement. I currently give seminars on Statement Analysis which are offered by Advanced Interviewing Concepts. I also speak at law enforcement conferences and give presentations to agencies conducting in-service training for their personnel. Listed below are some of the recent participants. U.S. Attorney's Office Internal Revenue Service Department of the Interior Office of the Inspector General Department of Justice Antitrust Division Center for Medicare & Medicaid Services Department of Health and Human Services I also assist law enforcement personnel by analyzing statements they receive from suspects. I give them my opinion as to whether the suspect is being truthful or deceptive and areas within the suspect's statement that need to be explored. I also assist attorneys in determining if a witness is telling the truth. If you are in law enforcement and would like for me to analyze a statement, please send me an email. This site is intended to familiarize you with the Statement Analysis techniques and to serve as a review for those individuals who have attended one of my seminars.
