My Topic: The lie detector is not accurate to use in the court as the evidence.

What I hope to learn from this source: From my peer review, friends say that if I put someone's famous saying, the essay will be more strong. So I want to find some famous saying to support my essay.

Notes. 

It is a transcript of the taped White House Oval Office conversation in which then President Richard M. Nixon uttered the infamous words, "I don't know anything about polygraphs, and I don't know how accurate they are, but I know they'll scare the hell out of people."

>>>>Final Thoughts: I will put his language in the part that telling about lie detector can make people scared.
