White House seeks to expand DNA database WASHINGTON  DNA profiles from juvenile offenders and from adults who have been arrested but not convicted would be added to the FBI's national DNA database under a Bush administration proposal. Under current law, only DNA from adults convicted of crimes can be placed in the national database, which is used to compare those samples with biological evidence from the scenes of unsolved crimes. As of January, there were about 1.3 million DNA samples in the database, U.S. officials say. http://www.usatoday.com/news/washington/2003-04-15-dna-usat_x.htm
