The idea of crime is very old in the globe and has developed alongside human evolution. Generally speaking, when humans began to live in societies, needs were created as humanity evolved. A list of do’s and don'ts was established for the populace in order to grant equality of rights and respect from society. It was noted and assessed that everyone in the society complied with the established standards of behavior; in the event that someone did not, the rules were enforced harshly to preserve the community free from evil. As a result, this idea developed into the process of looking into crimes and discovering how they were handled, which eventually helped establish the framework for numerous institutions that deal with trials and investigations in order to fairly administer justice to all. Many justice delivery systems are built around the evaluation of the truth and the determination of whether the victim is speaking the truth or is making false accusations out of malice. Before punishing any criminal, the testimony of the "eyewitness" was deemed crucial yet untrustworthy. It was found that in many instances, eyewitnesses were ineffective when coerced into making false statements or denying anything under duress from threats to their lives or financial inducements. As a result, these witnesses lost credibility in court and should not be fully trusted before determining a person's guilt. In addition, the criminal investigators used "third degree methods" on the perpetrators in an attempt to coax or uncover the truth from them. However, because of the shifting cultural norms and values, the methods used were deemed cruel and inhumane, violating established laws and human rights principles. As a result, innocent people frequently pay a heavy price, sometimes even losing their lives. With time and numerous scientific and technological advancements, criminal investigations also began utilizing cutting-edge scientific methods that helped solve cases quickly and reliably.
