Innocence and guilt with a polygraph

There are but times when people are accused of something they did not do and most of the time, they are put in jail without due process or having to go through the necessary steps to clear their names. Most of the time, these cases happen because of the individual in custody doesn’t have or cannot afford a lawyer. These persons might just be facing a life behind bars for something they did not do and no matter how hard they might try to convince the judge and jury about their innocence, the evidence might say otherwise.

There are of course, times when the evidence alone cannot prove whether the person of interest is guilty or not, there are a lot of factors that might contribute to the evidence collected in the crime scene that might make it inconclusive to the case. There is also the factor of mistaken identity in where the accused just so happens to look like the perpetrator and happen to be at the wrong place, at the wrong time. One sure way to clear an individual’s name is by going through a lie detector test. These tests were made to prove an individual innocent or prove that they’re actually lying through the skin of their teeth.

The difference between life behind and outside bars

Lie detector tests are very important in determining whether the accused is really telling the truth or is just faking it to gain sympathy from the jury. It can actually be the deciding factor whether the accused will face a life behind bars or walk out of the courtroom a free man.  Of course, one might think that polygraph results might be inconclusive to the overall results of the case since they have seen a lot of people cheat it, in the movies. Of course, it’s the movies. In real life, one can find it hard to cheat on a polygraph exam especially when coupled with an experienced examiner with a trained eye.

What if the accused is nervous?

One of the most frequently asked questions about polygraph exams is that will the individual fail it when they are nervous. Well, of course the polygraph will show that the person in question is nervous especially when asked certain questions, to an untrained eye, this might seem that they’re lying but to a well-trained examiner, they can identify whether the person in question is just straight out nervous or lying.

The spike on the polygraph test because of increased heart rate due to nervousness is different from that when a person is lying and seasoned examiners can detect it right away, which is why when having a polygraph test done, it is quite important to get a seasoned examiner with all the right credentials to make sure that the results of the polygraph exam are in fact, legitimate.

Criminal cases that involve mistaken identities are often hard to deal with especially if there is a lack of physical evidence and all the investigating parties have to go in is hearsay and eyewitness accounts which can often be quite unreliable especially if these witnesses are in a state of shock during the time of the crime. They can easily mistake an innocent individual for a culprit since their minds aren’t really in 100% working order as the shock can affect their memory, a lie detector test is a sure fire way to identify whether the person in custody is really innocent or just lying to get out of the sticky situation they have gotten themselves in.
