Current methods of forensic DNA profiling, based on Polymerase Chain Reaction amplifications of a varying number of Short Tandem Repeat loci found at different locations on the human genome, are regularly described as constituting the “gold standard for identification” in contemporary society. At a time when criminal justice systems in Europe and North America increasingly seek to utilize the epistemic authority of a variety of sciences in support of the apprehension and prosecution of suspects and offenders, genetic science and recombinant (...) DNA technology are often singled out for particular approbation. Indeed, the development and application of DNA profiling has been widely described as the “greatest breakthrough in forensic science since fingerprinting.”. (shrink)

Recent expansions of federal and state law enforcement databanks to include DNA samples and profiles of innocent persons threaten individual privacy, impose unjustifiable costs on society, and may undermine our pursuit of justice. The move to permanently retain DNA from arrestees and proposals for a universal database should be vigorously opposed on matters of principle, legality, and practicality.

DNA identification methods are such an established part of our law enforcement and criminal justice systems it is hard to believe that the technologies were developed as recently as the mid-1980s, and that the databases of law enforcement profiles were established in the 1990s. Although the first databases were limited to the DNA profiles of convicted rapists and murderers, the success of these databases in solving violent crimes provided the impetus for Congress and state legislatures to expand the scope of (...) the databases with little critical examination of each expansion's value to law enforcement or cost to privacy and civil liberties.We are now entering a new stage of DNA forensics, in which successive database expansions over the last decade have raised the possibility of creating a population-wide repository. In addition, new applications of DNA profiling, including familial and low stringency searches, have been added to DNA dragnets, the use of medical samples for forensic analysis, and other measures to create a series of crucial, yet largely unexplored, second-generation legal and policy issues.
