DNA testing not an exact science

7 October 2009

Professor Mark Findlay argues that DNA samples were too often relied upon as the only evidence in criminal prosecutions.

In an Australian Associate Press AAP Newswire report, Professor Findlay says that DNA testing is not an exact science.

"It's very easy for the analysis to be flawed because it goes through several hands and several stages," he asserts.

"People who look at that science - and they are lay people, judges and juries - are disproportionately impressed by it."

Professor Findlay's comments follow revelations that the criminal DNA testing process used by New South Wales led to a man's wrongful conviction, owing to a glitch.
