Sampling the DNA of convicted criminals and comparing it to crime scene DNA samples is the most significant innovation in crime-fighting since the science of fingerprinting was developed more than a century ago. Yet USA state legislatures are increasingly circumscribing its use.
Civil liberties groups are prominent opponents of expanded testing, claiming concerns over personal privacy.
However, since 1992, 70 prisoners – including eight on death row – have been released after DNA tests cast doubt on their convictions. More than 1,300 prosecutions have been aided when DNA profiles on state databases were matched via computer with suspects or evidence from crime scenes, according to the Federal Bureau of Investigation.

RSA Note:
South Africa lacks the variety of approaches adopted by the different American States in their efforts to find sound and just solutions to difficult issues such as DNA testing of suspects. Through trial and error the various jurisdictions eventually discover better approaches and adopt similar solutions. Countries with centralised power are inclined to act in a much more autocratic fashion and impose substantial costs on citizens in finding answers to vexing problems.
