When You Shed DNA, Do You Shed Your Right to Privacy Too?

Here's another reason not to smoke: being convicted of a crime. This article in the New York Times describes a new practice called "surreptitious sampling" in which police track a suspect until he or she inadvertantly sheds some DNA -- on a discarded cigarette butt, for instance, or a glass of water at a restaurant -- that can be tested against what was found at a crime scene. Opponents argue that the practice "violates a constitutional right to privacy," the article reports, while "law enforcement officials say they are just trying to solve crimes." Collection of this kind of accidental DNA sample has led to hundreds of convictions, the article says.
