Here are some random facts toward the polygraph argument:

The polygraph is always interesting to the public and to law enforcement, but is not and should not be used as any kind of absolute proof. Polygraphs can show both false positive responses and false negative responses. The Amer. Polygraph Association places the accuracy at about 87-89% and the Nat. Acad. of Science published a 2003 study showing this at 85-89%. Still, the government (FBI) does use them, such as for anyone applying for top secret clearance.

In no state can anyone be forced by the police or anyone else to take a polygraph examination. Almost every state fits into one of two categories; those that find them completely inadmissible and those that allow their admission with "the stipulations of both parties" (meaning both defendant and the prosecutor agree to admit the test results as evidence).
