Ever since there has been people roaming on this Earth, crime has existed. Criminal behavior is in our blood. Throughout the years crime has evolved, which gave us the need to evolve our crime solving skills, as well. We have increased our knowledge, technology, man power, and anything else you can think of to answer each criminal case with the truth.
One of these breakthroughs was the invention of the Polygraph machine, or as most people referred to them as lie detectors. This machine could actually measure all the sign your body gives off no matter how minuscule they are. Of course, like any other device people are skeptical. For example, the Polygraph can measure deceitfulness only if the examiner asks the right questions.
There have been ongoing arguments about whether or not the Polygraph should be administered in court as evidence. Speculators of the Polygraph machine argue that tests can be beaten by someone who believes that they are being truthful in the answers they are giving. However, the fact remains that this is only a piece of evidence and no case should be solely based on a lie test.
There are some states that would take a lie test as evidence, there are some states that are against it, and there are even some states that give the test in court in front of juries. Today there are at least 17 states that now admit the results of stipulated lie tests and polygraphic examinations as evidence. In my opinion, every state should allow for Polygraph tests to be used as evidence in courts because there is one vital piece of information I have not said yet; no one has to take the test if they do not want to. It is only for cases where both parties have agreed to take the test.
In today’s society the Polygraph machine is everywhere. There have been numerous shows, books and movies using this almost century old science.
