Over the past decade DNA analysis has emerged as the most reliable forensic technique for identifying criminals when biological material is left at a crime scene. Because of its scientific precision, DNA testing can, in some cases, conclusively establish a suspect's guilt or innocence. In other cases, DNA testing may not conclusively establish guilt or innocence, but may have significant probative value for investigators. While DNA's power to root out the truth has been a boon to law enforcement, it has also been the salvation of law enforcement's mistakes--those who for one reason or another, are prosecuted and convicted of crimes that they did not commit. In more than 75 cases in the United States and Canada, DNA evidence has led to the exoneration of innocent men and women who were wrongfully convicted. This number includes at least 9 individuals sentenced to death, some of whom came within days of being executed. In more than a dozen cases, moreover, post-conviction DNA testing that has exonerated an innocent person has also enhanced public safety by providing evidence that led to the apprehension of the real perpetrator. Clearly, DNA testing is critical to the effective administration of justice in 21st century America.
