DNA evidence would reduce the risk of wrongful conviction  The increased use of DNA evidence will minimize the risk of future wrongful convictions. An FBI study indicates that since 1989 DNA evidence has excluded the primary candidate in 25% of sexual assault cases1. This not only saves valuable police time, but ensures suspects are not called in for unnecessary and stressful questioning. Moreover, forensically valuable DNA can be found on evidence that has existed for decades, and thus assist in reversing previous miscarriages of justice. There have been a number of recent, high-profile cases of death row inmates being released on the grounds of DNA evidence, unavailable when they were first convicted. A DNA database would not merely render wrong verdicts right, but prevent such verdicts ever being made. 1 U.S. Department of Justice. (1996, June). Convicted by Juries, Exonerated by Science.
