FBI forensic review could free thousands of prisoners

But even DNA evidence is fallible: different labs can return very different results for the same sample. Paul Cates of the Innocence Project in New York, which campaigns for people wrongly convicted on the basis of DNA evidence, says that to date, 292 people have had their conviction overturned by follow-up DNA analyses. "In half of those cases, there had been some sort of forensics problem," he says.
Cates backs a recommendation in the NAS report, which called for a national body to set standards for forensic science so that all analysts would be consistent. "We're hopeful that Congress will take up this cause in short order to ensure that what passes as forensics is science," says Cates.
