A universal database resolves contentious issues, of whom, when, for what, and how long samples should be taken and kept. In addition, a compulsory database that collects an individual's DNA at birth, rather than at the first point of contact with the criminal justice system maximizes efficiency. If all United Kingdom citizens gave DNA samples at birth, the focus of the database could shift to ongoing investigations, as incoming profiles would almost certainly produce a match. There is no question that a mandatory DNA would increase clearance rates, improve the accuracy of the justice system, and decrease accusations of discrimination. However, citizens of the United Kingdom remain skeptical because they are distrustful of their government. This article briefly reviews the benefits of mandatory sampling. References
