DNA Fingerprinting, a method of forensic science, is a reliable technique that has been around for centuries that accurately compares fingerprints at crime scenes to the rightful owner. Since the early 20th century, research has proven that DNA fingerprinting is the leading form of crime scene forensic investigation and has solved more cases than any other method of investigation.
