Law enforcement officers have many different tools at their disposal during the course of a criminal investigation. One of the most controversial tools available to police is the lie detector test. Also known as polygraph examinations, these tests purport to elicit the truthfulness of a subject when answering questions from the police.
Unfortunately, these examinations are known to be unscientific and inaccurate. In fact, the results of these tests are so inaccurate the law does not permit the use of polygraph results at trial. Despite this, police frequently rely on these examinations in their effort to investigate crime.
If the police have asked you to submit to a polygraph test, it is a good idea to first speak to an attorney. Polygraph defense attorney David G. Moore could advise you on if it is a good idea to cooperate with the police or not in your case.
