DNA fingerprinting has considerable advantages over conventional means of forensic crime detection, advantages that render any slight fallibility irrelevant. Conventional fingerprints attach only to hard surfaces, can be smeared, or avoided by the use of gloves. Even a clear print requires a significant degree of interpretation by investigating officers. The standard technique of comparing fourteen points between the print taken at the crime scene and the print of the accused has been subject to severe criticism. The novel 'polymerase chain reaction' (PCR) amplification technique facilitates an accurate DNA profile from very small amounts of genetic data. The fingerprint can be constructed notwithstanding contamination from oil, water or acid in the crime scene environment. The innocent and the accused should appreciate a novel fingerprinting technique that is both objective and accurate. Lastly, fears of wrongful conviction are misguided, a 2002 study found only 'two cases worldwide'1. 1 Phillipson, G. (2009, November 19). The case for a complete DNA database.
