AUDIE CORNISH, HOST:
Massachusetts is reeling from a massive scandal in its state crime lab. The governor there has appointed a former prosecutor to assess the damage. Details are still emerging about what officials call a rogue chemist, who may have mishandled evidence in as many as 40,000 cases over ten years .
As NPR's Tovia Smith reports, this could mean the unraveling of countless convictions.
TOVIA SMITH, BYLINE: Even lawyers prone to hyperbole may not be overstating it, when they call the scandal a catastrophic failure and unmitigated disaster.
JOHN MARTIN: Any person who's been convicted of a drug crime in the last several years, whose drugs were tested at the lab, was very potentially a victim of a very substantial miscarriage of justice.
SMITH: Defense attorney John Martin represents the man believed to be the first convict sprung because of the scandal. He walked out of prison today, after a judge agreed his guilty plea was undermined by questions about the evidence. Those same questions may also undermine efforts to retry him. Even Martin concedes countless guilty people will probably go free.
MARTIN: Talented defense attorneys will be able to strongly suggest that any results from that lab are tainted. And people who deserve to be incarcerated for a very long time are going to walk. And that's the reality of it.
SMITH: Even prosecutors supported the defendants' release today, saying the Constitution demands it and it's, quote, "not the end of the fallout."
District Attorney Joe Early, head of the DA's association, says prosecutors will move on some cases even before defense attorneys ask.
JOE EARLY: The DAs are used to putting in jail. They're not used to letting them out because of technicalities or mis-testing. In that regard, a lot of people have some tough decisions to make.
SMITH: The attorney general is investigating the chemist, Annie Dookhan, who's accused of tampering with samples to make them weigh more or even to test positive. She and three others have already lost their jobs, including the Department of Public Health Commissioner John Auerback, who says supervisors should have picked up on red flags.
Dookhan was caught a year ago, failing to sign out evidence or signing other names, and was handling three times the normal caseload.
JOHN AUERBACK: That the actions of a single person could case so much damage and possibility that justice was not served, I'm furious at that.
SMITH: As are defense attorneys like Max Stern, who are already buzzing about civil suits.
MAX STERN: There are many people who, you know, for years have not been able to get jobs, not be able to get drivers license, not be able to live in particular housing. I mean, there are enormous consequences nowadays to drug convictions.
SMITH: It's still unclear what the chemist's motive may have been. But if some innocent defendants were wrongly convicted, former prosecutor Wendy Murphy says people should be equally concerned about bad guys who may have gotten off.
WENDY MURPHY: There is no legal remedy. Prosecutors cannot go back in front of a judge and say, I want this wrongfully acquitted man to be brought back up on charges, because double jeopardy would bar that remedy. And that's a problem for the public.
SMITH: Former federal judge and now Harvard Law professor Nancy Gertner agrees the crime lab scandal could, as she says, turn the system on its head. She says courts might dismiss cases not only because of tainting, but also just to punish and deter misconduct.
NANCY GERTNER: There have been times when government misconduct was so outrageous, the only response is to dismiss charges. It doesn't happen very often, it takes extreme situations. But this is a level of negligence which is really stunning.
SMITH: The crime lab in question used to be run by the Department of Public Health but is now under the state police, as in most other states.
But Northeastern Law professor Daniel Medwed says that can be problematic.
DANIEL MEDWED: There are often implicit pressures to help out prosecutors, to testify in cases in a way that supports their perceived colleagues in law enforcement.
SMITH: A legislative panel is looking into possible reforms. Prosecutors say the obvious answer is better oversight.
