What are the principle of operation of lie detector?
Lie detectors, or polygraph machines as they're more officially known, are large contraptions that are filled with buttons, levers, paper, and measuring devices. They have been used for years in law enforcement to detect whether or not someone is actually lying to officials. The reason why people would lie to law enforcement officials is obvious - they committed a crime that they don't want to get caught for. Lie detectors can help solve this problem by asking a person who's strapped to a lie detector several questions and then analyzing the results. However, lie detectors still aren't permissible in court. This means that should a person fail a lie detector, they will not be able to be proven as lying in a court of law. And likewise, a person will not be able to use the results of a lie detector test to prove that they are telling the truth. This is because lie detectors can't actually detect if a person is lying. They can only tell if the person is displaying deceptive behaviour.
Are lie detector tests admissible in Louisiana courts?
No. Although lie detectors seem credible, they can be often faked to produce response opposite to what you want. The lie detectors lack the hard evidence that normal court order can provide (such as blood stain, DNA analysis, etc) and relies solely on how stressed the person is. Even when you didn't commit the crime, extremely high level of stress can tick the lie detector. Similarly, even when you did commit the crime, low level of stress can fool the lie detector. Some people say that lie detectors have a 99% chance of succeeding. It is that 1% that makes the people say "No, we don't want it."
