Forensics science is getting more and more popular today. But what is forensics all about?
Although popularly referred to as forensics, forensics science consists of a wide range of applications related to the legal system both for civil and crime actions. In more recent years, life-based documentaries and television crime series have made forensics science a part of popular culture. Such materials depict the way a forensic investigation is conducted at the crime scene for instance. Thus, according to the laws and methodology of forensics science, experts gather all the information that is to be used in a court of law for the conviction of a criminal.
The practice of forensics science is nothing new and it seems to have been specific to certain cultures since the days of the Roman Empire. Chinese and European records do confirm such evidence. By the 18th century, legal systems had already started using treatises in support of forensic medicine meant to clarify deaths and justify prosecution. This is how medical experts even came to detect arsenic intoxication, thus, managing to deal with poisoning cases. Such steps in police diagnosis contributed to the development of the forensics science as we know it today.
The sub-divisions or applications that are classified into forensics science categories include toxicology, criminalistics, forensic geology, forensic anthropology, applied science and so on. As we can see from such examples, forensics serves for more than the act of justice alone. There are certain subdivisions that serve well for archaeological, ethnological and geographical purposes. Forensic anthropology identifies human remains, and enables the study of past cultures and historical contexts as they appear on site.
There are some aspects of forensics science that have caused a lot of debate, and they still remain less scientific than they were believed to be. For the moment, forensic dentistry can no longer convince whether the bite marks belong to one person, without any shade of a doubt. Many convicts were released in the US, in 1999, precisely because the dental evidence that was used for their conviction could have been wrong. Several other controversies fire up spirits, but like all the other domains, forensics science has made progresses and improved over the years.
