A federal judge this week unsealed the source code for a software program developed by New York City’s crime lab, exposing to public scrutiny a disputed technique for analyzing complex DNA evidence.

Judge Valerie Caproni of the Southern District of New York lifted a protective order in response to a motion by ProPublica, which argued that there was a public interest in disclosing the code.

“Everybody who has been the subject of an FST report now gets to find out to what extent that was inaccurate,” said Christopher Flood, a defense lawyer who has sought access to the code for several years. “And I mean everybody — whether they pleaded guilty before trial, or whether it was presented to a jury, or whether their case was dismissed. Everybody has a right to know, and the public has a right to know.”
