The National DNA Database - Is It Worth the Risk?
In the past decade, genetic testing has become increasingly popular. Private companies, such as 23andMe have made genetic testing more accessible to the public, and allowed people to trace relatives and construct family trees and detect their susceptibility to disease. The improvement in DNA analysis technology and forensic DNA databases have also helped police to convict criminals charged with rape or homicide. However, it is not a good idea to have national DNA databases which would include all individuals - not just those who have been arrested or convicted for federal offenses or misdemeanors.
DNA provides information about an individual’s gender, ethnic appearance, and genetic relationships. …show more content…

Forensic DNA databases contain DNA profiles of individuals who were involved in crimes, and this information can be shared used by international police forces. (“Is It Ethical”) In the United States, the 2008 Counter-Terrorism Act allowed security personnel to use a method known as Biosurveillance, tracking individuals by traces of DNA, to combat terrorism. However, national DNA databases contain millions of DNA profiles which increases the databases’ vulnerability to hacking. If these a national DNA database is hacked, terrorists and organized crime groups can use DNA profiles to hunt individuals and their relatives. Children, who have been separated from their parents for safety, could be tracked down by their parent using Biosurveillance. Additionally, individuals in witness protection programs will no longer be protected. These individuals can alter their identity, but they can still be traced by their …show more content…

The UK had one of the first national databases, but it did not increase the likelihood of prosecution, and it lowered the public’s trust and confidence in the police. From 2005-2006, only 0.37% of all recorded crimes were resolved using DNA detection (Levitt). Also, individuals do not need to have a DNA profile in a national DNA database to be exonerated from a crime. In the United States, The Innocence Project exonerated many innocent convicts, including some on death row, by taking their DNA sample to compare directly to the DNA sample found at the crime scene. Additionally, large numbers of DNA samples increases the likelihood of errors in the lab procedures or analysis. DNA profiles do not consist of a person’s entire DNA sequence. Instead, scientists use short tandem repeats (STRs), a sequence of 2-6 base pairs that repeats in the genome. Short tandem repeats are useful because they can be replicated using polymerase chain reaction (PCR) amplification. Even though only a small part of the person’s DNA is included in the profile, it is unlikely to match another person’s profile. In the United Kingdom, ten STRs from different places in the genetic sequence are used to create a genetic profile, and the match probability is one-in-a-billion; however, a match is more likely to occur among relatives. It is difficult to
