"The rise of DNA profilingIT HAS revolutionised policing. In 10 years, the England and Wales National DNA Database (NDNAD) - the largest in the world - has matched nearly 600,000 suspects to crimes. This extraordinary success has been possible because police have unprecedented powers to retain samples from suspects, and other countries are following suit. But some experts argue that NDNAD's size and power mean it poses a serious threat to civil liberties."
