Lie Detector Test

When lie detectors were made for the first time, they were used only by law enforcement agencies to find out the truth from suspects for various crimes.

But at this day and age, experts have managed to create advanced equipment using best materials and latest technology. Hence lie detectors which are available now are more accurate and widely used.
