It is of course very unfortunate that this man had to spend 8 months in jail. There was no lab error in this case (the man was a cab driver with a rare skin flaking condition and his skin flakes stuck to the nail polish of a passenger who was later the victim of murder). But of course errors do happen, someone in this thread quotes a 1% to 2% error rate for DNA testing. Buit to put it in context, according to the Innocence Project, in 25% of the cases when DNA testing is used by the FBI during the investigation, it results in the suspect being exonerated. That 25% is a large number of innocent people who would be charged and tried and a lot of them would be convicted if not for the existence of DNA testing.
