One legit angle might be cases involving memory loss from automobile or other accidents which may have taken human life- so-called Vehicular homicides. they usually call in Pyschiatrists and there is always the possibility the person being tested may be faking amnesia ( memory blot outs or loss). Another possibility is the test subject may be in fear for their own life ( from accident) and will tell the police anything they want to hear- to get them off their back- nerves, or whatever. there are balancing acts between Police fact-finding and medical compassion. if the test subject is drunk- well you know Sarge, I was coming down the Boulevard and I saw this huge Pink Dinosaur and I put on the brakes, but... oh boy.

A PolyGram is a figure that consists of many stripes. These stripes are known as lines, and polygraphs are used in math and technology.
The legality of using lie detectors, or polygraphs, varies by country. In the United States, their use is common in specific contexts, such as employment screening and criminal investigations, but results are not typically admissible in court. In the United Kingdom, polygraphs can be used in certain circumstances, such as for monitoring sex offenders, but are not widely accepted in legal settings. Other countries, like Canada and Australia, have more restricted or limited use of polygraphs, primarily for investigative purposes rather than as definitive evidence.
Although the use of polygraph results as evidence in court is regularly challenged - it IS a useful tool and is used in the preliminary stage of many criminal investigations.
Polygraphs are seldom if ever used on juveniles who are suspected of committing petty offenses.
Yes, lie detector tests, or polygraphs, can be conducted in Ireland, though they are not widely used or accepted in legal settings.

The selective use of polygraphs by corrupt FBI officials must stop! No one is above the law, including FBI Director Robert Mueller, who conspired to cover up the Pan Am Flight 103 incident. Google "Quadri-Track ZCT"
Legally, polygraphs are generally not admissible in criminal trials, and are therefore rarely, if ever, used. In general, polygraphs are not considered reliable enough to be scientific evidence. However, people will often volunteer to take a polygraph as part of a criminal investigation. Oftentimes, private companies and government agencies require polygraph examinations as part of the hiring and continuing employment process. In this case, a polygraph would be necessary to get/retain the job.
The official name for someone who conducts polygraphs is a "polygraph examiner" or "polygraph operator." These professionals are trained to administer polygraph tests, interpret the results, and provide reports based on their findings. They often work in various settings, including law enforcement, private investigations, and security screenings.
Polygraph tests, commonly known as lie detector tests, have been used in various court cases, though their admissibility varies by jurisdiction. While some courts accept polygraph results as supplementary evidence, others exclude them due to concerns over their reliability and the potential for misleading juries. For instance, in the 1998 case of United States v. Scheffer, the U.S. Supreme Court ruled that the exclusion of polygraph results did not violate a defendant's rights. Overall, the use of polygraphs in court remains controversial and often depends on the specific legal context.
