DNA evidence has exonerated over 140 wrongly convicted capital defendants in the United States. Just as DNA is often effective in providing a remedy to the wrongly accused, it is also an extremely powerful resource for law enforcement. At first blush, this may appear to be a “win-win” scenario for all concerned (except, of course, for defendants who are actually guilty), but the expanding use of DNA evidence, particularly in cases involving DNA databanking, has met substantial resistance on the civil-liberties front. When examining the privacy implications involved with DNA sampling, it is enlightening to compare constitutional analyses of two DNA databanks—one from convicted criminals and a similar sampling required of members of the United States Armed Forces.
