The False Promise of DNA Testing
"...Modern forensic science is in the midst of
a great reckoning. Since a series of high-profile legal challenges in
the 1990s increased scrutiny of forensic evidence, a range of
long-standing crime-lab methods have been deflated or outright debunked....
DNA typing has long been held up as the exception to the rule—an
infallible technique rooted in unassailable science. Unlike most other
forensic techniques, developed or commissioned by police departments,
this one arose from an academic discipline, and has been studied and
validated by researchers around the world....
The problem, as a growing number of academics see it, is that science is
only as reliable as the manner in which we use it—and in the case of
DNA, the manner in which we use it is evolving rapidly."
