Mark P. Smith at Expert Polygraph Testing has conducted over 5,000 polygraph examinations over his successful career. Below are three sample cases in which his polygraph services cleared the people falsely accused of wrongdoing.
An individual was arrested and lodged in county jail on a first degree robbery charge. Two eye witnessed picked the individual out of photo line-ups and were “100%” certain he was the assailant. His attorney requested that a polygraph examination be administered by Mark. The accused passed the test prompting police to re-interview the victim. As a result, the actual assailant was arrested and the attorney’s client was released from custody.
An individual was arrested on domestic violence-related charges for threatening their former spouse with a handgun. At the time of the arrest the handgun was found in the accused’s vehicle. After passing Mark’s polygraph test the spouse admitted they fabricated the assault and planted the gun in the accused’s vehicle.
A county prosecutor's office dismissed 1st degree aggravated sexual assault charges against an individual after agreeing that Mark's polygraph cleared the individual.

Three training seminars are currently offered: How To Spot A Liar, Winning the Interviewing War and Monsters Among Us. Below is a summary of each course.
People in all professions are constantly confronted with situations where they need to know the truth. Money, careers, reputations and more are often at risk when we are deceived. Unfortunately, studies repeatedly show that most people are bad lie detectors. We just don't know when people are lying to us. Even some professionals who critically need to know the truth such as judges, prosecutors, police, salespersons, psychologists, psychiatrists and others consistently score no better than chance (50%) in their ability to spot a liar. This training course will discuss:
By the end of the training program attendees will know the easiest, most effective way to spot a liar, they will have enhanced listening skills and they will be more successful, productive and effective at their jobs. The instructor is a retired detective, now a private investigator and polygraph examiner, who has interviewed and polygraphed hundreds of suspected liars and the wrongly accused.
The ability to conduct an effective and successful interview is the single most important skill a business professional can have. Yet most professionals receive little or no training in this critical area. This training course will provide attendees with the tools necessary to "win the interviewing war." The following concepts will be discussed:
By the end of the training program attendees will be better and more confident interviewers. They will understand the psychological forces at work and utilize them to gain compliance from their subjects. They will obtain more information in less time, thereby becoming more efficient and effective in their positions.
Almost every day we hear of a new child sexual abuse scandal. But how many of us know what is behind those scandals? Who are these people who abuse children for sexual gratification? They are teachers, clergy, FBI agents and the guy next door. This graphic and compelling seminar will introduce attendees to the world of pedophiles, examining who they are and why they commit the crimes they do.
But instead of a dry, textbook approach, attendees will hear directly from offenders themselves, through written and audio statements and interviews. What they say will shock you. In addition, some of the literature and paraphernalia possessed and used by pedophiles will be examined first hand.
This is a multi-media presentation utilizes PowerPoint, audio and video tapes. The instructor, a retired detective and polygraph examiner, has spent the last 12 years interviewing and polygraphing sex offenders.

The polygraph is a scientific instrument that measures involuntary reactions in the autonomic nervous system that occur when people lie. These are reactions that occur within the body that cannot be physiologically controlled.
The polygraph is very accurate. The Department of Defense puts the polygraph's accuracy above 90%. A recently released study by the National Academy of Science reported accuracy of 91% for specific issue tests. It is commonly accepted that opinions and evaluations done by professionals such as psychologists, psychiatrists and therapists of their patients are accurate about 63% of the time. The polygraph can top that by a large margin.
The polygraph is not infallible, but it is very hard to "beat." Studies by the Department of Defense show that people who try to "beat" the polygraph actually increase their negative score. In addition, modern, computerized polygraphs come with countermeasure systems built in that will detect attempts to "beat" the instrument. If it was as simple as the $39.99 "beat the polygraph" kits you can buy on the internet tell you, wouldn't the terrorists and other national security threats who are being polygraphed every day use these "systems?" Save your money!
Polygraph exam takes approximately 90 minutes or more. We will work with you to conduct a test that fits your budget.
A polygraph examination consists of several steps. First, background information is collected. Second, the relevant issue is discussed. The test subject is asked to provide all the information, if any, they have about the issue. The third step is the formulation of questions. A list of 9-13 questions will be compiled by the examiner based on the statement provided by the subject. All questions are simply worded and have a "yes" or "no" answer. All questions are then reviewed with the subject, word for word. Contrary to what is shown on television there are no "trick" questions. The test subject will know every question to be asked on the test beforehand. The fourth step is the actual collection of charts. During this phase the questions will be asked slowly, one at a time. A minimum of two separate tests are conducted (often a third test is also run). The final step in the examination is the discussion of the results with the subject.
Save your money. Virtually every study ever done on voice stress analyzers show that IT DOESN'T WORK! Most have shown that there is no basis in science for these machines. If voice stress did work it would have been added as another component to the polygraph long ago. Here's what ABC News said (March 30, 2006: A Pentagon study obtained by ABC News finds that a new kind of voice lie detector used by the U.S. military and American police departments is no better than "flipping a coin" in detecting lies. Until the Pentagon ordered a halt to its use, the Voice Stress Analyzer was being used by military intelligence interrogators at Guantanamo Bay and in Iraq. Several suspected terrorists were released from custody based on the machine's results and former Iraqi deputy prime minister Tariz Aziz was one of the many "high value targets" who were hooked up to the now discredited machine.
