“Adamski’s dirty and he’s going away for a very long time, but Briel’s actions make you wonder.” Ryan spoke without turning to face me. “How many guilty have gone free, and how many innocent have been convicted because of bad police or forensic work?”
“You’ve heard of the Innocence Project?”
Ryan nodded.
“In the last twenty years there have been over two hundred exonerations in the U.S., some involving inmates on death row. More than a quarter, fifty-five cases with sixty-six defendants, involved forensic testing or testimony that was flawed. And those stats don’t begin to tell the whole story.”
Ryan added a log. Embers spiraled, Lilliputian fireworks in the dim hearth.
“Forensic science is popular right now, and people with minimal or no training are hot to be players. Briel is a perfect example. She learned a little about bones and hung out her shingle as an anthropologist.”
“With predictable results,” Ryan said.
“Whether it’s bad methodology, sloppy performance, or intentional misconduct, jurors can’t always spot junk science. If an expert wears the white lab coat, it’s science.”
Returning to the couch, Ryan sat closer.
“Cops and lawyers have the same problem,” he said. “How are we average joes supposed to know who’s legit?”
“That’s the point of board certification. Every field has it now. The American Board of Forensic Anthropology, Engineering, Entomology, Odontology, Pathology, Toxicology, etc. Accreditation is a rigorous process.
“Board certification isn’t a perfect answer, Ryan. Sure, some incompetents slip through, just as in law or medicine. But it’s a start. Those letters behind a scientist’s name aren’t just for show. They’re hard-earned. And they’re a message that an expert has undergone peer scrutiny and meets a high set of ethical standards. And being certified in one field doesn’t mean you’re an expert in another.”
“Briel’s not certified in forensic anthropology.”
“Of course she isn’t. It takes a PhD and years of experience to qualify for ABFA candidacy. Being a pathologist doesn’t make you an anthropologist, or vice versa.”
For several moments we listened to the hiss and pop of the logs.
My eyes drifted to a bouquet on the dining room table. LaManche. His gift had been the first to arrive.
“This would never have happened on LaManche’s watch,” I said. “He’d never use a noncertified expert.”
“The old man would have seen through Briel,” Ryan agreed.
“I hope he’s doing well,” I said.
“So do I.”
Ryan took my hand. Firelight danced in his eyes and bathed his face with a warm, honey glow.
“Are we, buttercup? Doing well?”
I hesitated.
“Yes, dandelion.”
I smiled.
“Very well, indeed.”
FROM THE FORENSIC FILES OF DR. KATHY REICHS FROM THE FORENSIC FILES OF DR. KATHY REICHS CAMELOT? OR SCAM A LOT?
In this special essay, Kathy Reichs discusses the imperfect relationship between science and the criminal justice system.
“
She’s worried about bad forensic science.
A lot of us are.
Today, science is a routine and crucial tool of the criminal justice system. A latent fingerprint places a defendant at a crime scene. DNA from sperm links an accused to a rape victim. Chemical analysis determines that a drug is illegal. An autopsy establishes that a death is homicide.
The forensic science community includes a wide array of practitioners: anthropologists, biologists, chemists, entomologists, odontologists, pathologists. On television these scientists are portrayed as knights in shining lab coats.
No question. Science is powerful. But does it always smite with the unerring stroke of Excalibur? Is every expert a gallant champion for justice and right?
Recent findings suggest things aren’t perfect in Camelot.
Thus Tempe’s unease.
“
Tempe speaks of the Innocence Project, a national litigation and public policy organization dedicated to finding justice for those wrongfully imprisoned. Numbers have risen since her fireside chat with Ryan. As of this writing, 234 convicted persons in the United States have been exonerated through DNA testing.
How could our courts err in so many cases?
Each “forensic science” has its own methodologies, technologies, practices, and standards. There is significant variability with regard to reliability and potential for error. Some specialties are analytical and laboratory based: DNA analysis, toxicology, drug analysis. Terra firma. Others rely on pattern interpretation: fingerprints, hand writing, tool and bite mark analysis. Shakier ground.
“
Examples abound. An expert in Illinois relocated to Texas testified on lip print analysis, an anthropologist on identification through shoe prints. Neither methodology had been validated. Using goggles and a blue laser, a dentist in Mississippi identified bite marks, scratches, and other injuries that no one else saw. His results can’t be photographed or reproduced.
A chemist in Tennessee, later Texas, routinely presented inconclusive findings as conclusive, altered laboratory records, and reported scientifically impossible or improbable results. A Toronto doctor performed over a thousand autopsies on children, though he never certified in forensic pathology.
Innocent people went to jail. Mothers lost custody of their kids. Perpetrators who could have been convicted were acquitted.
Tempe doesn’t like it. And she’s not alone.
Recently, the Science, State, Justice, Commerce, and Related Agencies Appropriations Act of 2006 became law. Under the terms of the statute, Congress tasked the National Academy of Sciences with evaluating the state of forensic science in the United States. On February 18, 2009, the NAS issued its long-awaited report.
It was a doozy.
The report described disparities in forensic science
