Forensic Sciences
According to a dictionary, the definition of the word “forensics” is, “the use of science and technology to investigate and establish facts in criminal or civil courts of law.” The use of forensics has been used to aid the investigations of crimes for over a century. Although investigating crime scenes is not exactly the same as it used to be in the beginning, investigators still use the basics but have just added the help of science to more accurately prove a suspect. Forensic science is a valuable aid in assisting both the police and the courts in bringing the accused to justice by evidence such as fingerprints, DNA, firearms, shoe prints, forensic psychiatry, and polygraph testing. In around 1750 BC, people in Babylon used fingerprints to sign their identity on clay tablets. The first time ink prints were used in China around the year 220 BC fingerprints became a forgotten item. This all changed in the late 1850s when Sir William Herschel demanded labourers to sign contracts with fingerprints. Eventually, as year went by fingerprints became known as unique to everyone and became more used during crime scene investigation in the early 1900s.
