Foes of the United States have demonstrated their ability to strike at the heart of this country. Fear of renewed attacks and a desire for greater national security have now prompted many to call for improvements in the national personal identification system. In particular, the possibility of a national identification card containing the carrier's DNA information is being seriously considered. However, this raises difficult questions. Would such a card system, and the extraction of individuals' DNA it entails, violate the 4th Amendment of the Constitution? This article will show that such a card system could in fact be found to be constitutional under the law of privacy as it stands today.
