The DNA of the suspect can then be compared to any genetic material found at the scene of the crime.The creation of a database of DNA would allow police to use DNA in order to search for a suspect, rather than merely to provide evidence once a suspect has been apprehended.

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.

It is likely that more crimes will be prosecuted on account of largely circumstantial evidence. Moreover, there is the possibility that not only the police, but also the jury, will be blinded by science. It seems unlikely that juries will be able to comprehend, or more importantly, to question, the genetic information that is yielded by the database. The irony is that forensic evidence has been instrumental in establishing the miscarriages of British justice in the 1970s, but might now serve to create miscarriages of its own.
