What are the basic functions of the polygraph, and what is its legal status in the courts?

What will be an ideal response?


There are two major uses of polygraph testing in policing: specific issue testing and pre-employment screening. Specific issue testing involves using the polygraph to investigate whether a particular person is responsible for or involved in the commission of a specific offense. Use of the polygraph for pre-employment screening is very controversial and is illegal in some jurisdictions.

Some courts do admit polygraph evidence even over the objection of counsel. In other jurisdictions, polygraph results are admitted by stipulation. At the federal level, there is no single standard governing the admissibility of polygraph evidence.
