Collecting DNA: database mission creep.SINCE DATABASES of DNA DNA: see nucleic acid. DNA or deoxyribonucleic acid One of two types of nucleic acid (the other is RNA); a complex organic compound found in all living cells and many viruses. It is the chemical substance of genes. taken from convicted criminals have proven such a success in forensic investigations, why not create a universal one covering all citizens? So suggested James Hodge, director of the Center for Law and the Public Health at Johns Hopkins University Johns Hopkins University, mainly at Baltimore, Md. Johns Hopkins in 1867 had a group of his associates incorporated as the trustees of a university and a hospital, endowing each with $3.5 million. Daniel C. , during a February forum sponsored by the National Academies, an advisory body for national science policy. That isn't a serious policy proposal in D.C.--yet--but don't count it out. Forensic DNA databases, the first of which was created in 1989, initially included only violent felons for whom such evidence could be crucial, such as rapists and murderers. But they have expanded to include all felony prisoners, many people on probation, and, in most states, all juvenile offenders and all people convicted of misdemeanors. At least four states take DNA samples from everyone arrested for any reason, even before conviction. In January President George W. Bush signed a law authorizing the reds to do the same with their arrestees and noncitizen detainees. These DNA samples are used to create computerized searchable "profiles" in the FBI's Combined DNA Index System Noun 1. Combined DNA Index System - the DNA file maintained by the Federal Bureau of Investigation , which contains nearly 2.8 million such profiles. The samples themselves, which are available for re-analysis at any time, can reveal all sorts of personal information, including genetic predispositions genetic predisposition Molecular medicine The tendency to suffer from certain genetic diseases–eg, Huntington's disease, or inherit certain skills–eg, musical talent to diseases or addictions. Testing labs already have enormous backlogs of samples waiting to be turned into profiles, and such overloading can lead to screw-ups. In one of the more notorious cases, a sloppy lab in Houston produced a bad DNA analysis DNA analysis Any technique used to analyze genes and DNA. See Chromosome walking, DNA fingerprinting, Footprinting, In situ hybridization, Jeffries' probe, Jumping libraries, PCR, RFLP analysis, Southern blot hybridization. that falsely convicted accused rapist Josiah Sutton in 1999.Widening the DNA database to include all arrestees, much less all Americans, greatly increases the chances of such bad forensic science The application of scientific knowledge and methodology to legal problems and criminal investigations. Sometimes called simply forensics, forensic science encompasses many different fields of science, including anthropology, biology, chemistry, engineering, genetics, . |
