Vaughan Bell: the truth about lie detectors
My Topic: The lie detector is not accurate to use in the court as the evidence.
What I hope to learn from this source: I want to find the example of the person who was damaged from the lie detector's result. And I found this example through the article.

Notes.
The example from the article
With his dying breath, Fred Ery identified Floyd "Buzz" Fay as his murderer. "Buzz did it," he whispered to his wife, even though the assailant had covered his face and fled quickly from the scene. Ery had been shot as he worked late in his small general store but managed to give Buzz's address shortly before he died on the operating table. Only a few hours later, the police had Buzz's house in Ohio surrounded. When Buzz was charged with aggravated murder, he didn't seem particularly perturbed. "I kept thinking, they'll find the right person, they'll get this straightened out, they'll let me go tomorrow," he told the Calgary Herald, "I wasn't even going to hire a lawyer."

The county prosecutors offered Buzz a deal: they would drop all charges if he agreed to take a polygraph – a lie detector test – to prove his innocence. Convinced the whole episode was one big mistake, Buzz readily agreed. He took two tests but both suggested he was lying about his innocence. This, along with circumstantial evidence, sealed his 1979 conviction and he spent two-and-a-half years in prison for a murder he didn't commit.
During his time in prison, Buzz studied the polygraph. He sent his results to a number of experts but received wildly different interpretations. Determined to show the test was fallible, he developed a training exercise to help people fool the lie detector and after just 15 minutes of instruction, 23 out of 27 inmates beat the polygraph. Buzz was eventually exonerated, helped by the testimony of the real killer's mother, and his case has become one of the most notorious episodes in the history of the technology.
### Summary
The lie detector is not accurate and here is the example to support my opinion. Buzz was damaged by the lie detector's inaccuracy, because he is innocent, but the lie detector said he is lying about his innocent. So he spent years because of the lie detector's inaccuracy.
>>>>Final Thoughts: Through this example, we can know the lie detector's inaccuracy. And if we use the lie detector as the evidence in the court, many examples like Buzz's will occur.
