Jeff Sessions orders Justice Department to end forensic science commission


WASHINGTON, DC: Attorney General Jeff Sessions will end a Justice Department partnership with independent scientists to raise forensic science standards and has suspended an expanded review of FBI testimony across several techniques that have come under question, saying a new strategy will be set by an in-house team of law enforcement advisers.

In a statement Monday, Sessions said he would not renew the National Commission on Forensic Science, a roughly 30-member advisory panel of scientists, judges, crime lab leaders, prosecutors and defense lawyers chartered by the Obama administration in 2013.

A path to meet needs of overburdened crime labs will be set by a yet-to-be named senior forensic adviser and an internal department crime task force, Sessions’ statement said.

The announcement came as the commission began its last, two-day meeting before its term ends April 23 and as two of its most wide-reaching final recommendations remain hanging with the department. Two officials said no decision has been made on calling for the Justice Department to set written standards for examining and reporting forensic evidence in criminal courts across the country. A second proposal to more fully disclose the statistical limits of results is to be voted on by the commission this week.

“The availability of prompt and accurate forensic science analysis to our law enforcement officers and prosecutors is critical to integrity in law enforcement, reducing violent crime, and increasing public safety,” Sessions said in the statement. “We applaud the professionalism of the National Commission on Forensic Science and look forward to building on the contributions it has made in this crucial field.”

The action marked the latest break by Sessions, a former federal prosecutor, with Obama-era priorities. The former Alabama senator last week announced top aides will review agreements reached with troubled police forces nationwide to ensure the pacts to overhaul departments do not counter the Trump administration’s goals of combating violent crime and promoting police safety and morale.

Obama, a constitutional law scholar, had championed changes to forensic science.

In September, a White House science panel called on courts to question the admissibility of four heavily used techniques, including firearms tracing, saying claims about their reliability had not been scientifically proven. The Justice Department last year also announced a wider review of testimony by experts across several disciplines after finding that nearly all FBI experts for years overstated and gave scientifically misleading testimony about two techniques the FBI Laboratory long championed: the tracing of crime scene hairs based on microscopic examinations and of bullets based on chemical composition.

The wider review has been suspended, according to two Justice officials tracking the effort, pending a strategy to be devised by the internal task force with input through public comments. Options could include using a different commission, a Justice Department office or a group composed of representatives from many agencies.

Sessions has made clear quality forensic evidence is important for the entire criminal justice system, “enabling us not only to convict the guilty but to clear the innocent,” Associate Deputy Attorney General Andrew D. Goldsmith noted in remarks prepared to begin Monday’s commission meeting in Washington.

In his statement about the future of forensic sciences, Sessions highlighted the need to survey crime lab workloads, backlogs and equipment needs as a way to increase the labs’ capacities to do work, and the need for reliability and “specificity” of results.

Even before the announcement not to renew the national commission, several commission members from outside the Justice Department warned against ending its work, saying the Trump administration has made several moves to reduce the role of science and independent scientists in policymaking.

In a letter Thursday, six leading research scientists on the panel urged re-upping the commission for another two-years saying “for too long, decisions regarding forensic science have been made without the input of the research science community.”

“Limiting the ‘relevant scientific community’ to forensic practitioners is a disservice to that field and to the criminal justice system,” they wrote, led by Thomas D. Albright, an internationally recognized neuroscientist specializing in vision and the brain at the Salk Institute for Biological Studies.

The full commission declined to recommend its renewal, on a 16 to 15 vote in January, the Justice officials noted.

The commission jointly led by the Justice Department and the Commerce Department’s National Institute of Standards and Technology or NIST, has prompted several changes.

Carrying out one recommendation, NIST launched a $20 million research effort to solidify understanding of whether techniques used hundreds of thousands of times a year in U.S. crime labs work as advertised – including such questions as how often claimed matches of pattern-based evidence such as fingerprints, bullets, firearms and bitemarks may be in error.

Sessions’ predecessor as attorney general, Loretta E. Lynch, also accepted commission recommendations to set new accrediting and ethical codes for forensic labs and practitioners.

Several commission members who have worked in criminal courts and supported the input of independent scientists said the department risks repeating past mistakes, saying that no matter how well-intentioned, prosecutors lack scientists’ objectivity and training.

U.S. District Judge Jed S. Rakoff of New York, the only federal judge on the commission, said “it is unrealistic to expect that truly objective, scientifically sound standards for the use of forensic science . . . can be arrived at by entities centered solely within the Department of Justice.”

Any move “to retreat back into DOJ and forgo public dialogue with scientists and stakeholders will not improve the forensic disciplines,” said Julia Leighton, former general counsel for the Public Defender Service for the District of Columbia, where three of seven defendants convicted at trials involving FBI hair matches have been exonerated through DNA after serving 20 to 30 years in prison for rape or murder.

“Good science thrives on transparency. Junk science survives only when sheltered,” said Leighton.

However, the National District Attorneys Association, which represents prosecutors, last month in House testimony called for the commission to end and be replaced by an Office of Forensic Science inside the Justice Department, saying disagreements among members had reduced the commission “to a think tank.”

The commission was created following critical reports by the National Academy of Sciences about a dearth of standards and funding for crime labs, examiners and researchers, problems it partly traced to law enforcement control over the system.

Although examiners had long claimed to be able to match pattern evidence – such as with firearms or bitemarks – to a source with “absolute” or “scientific” certainty, only DNA analysis had been validated through statistical research, scientists reported.

In one case, the FBI lab in 2005 abandoned its four-decade-long practice of tracing bullets to a specific manufacturer’s batch through chemical analyses after its method were scientifically debunked. In 2015, the department and bureau reported that nearly every examiner in an elite hair analysis unit gave scientifically flawed or overstated testimony in 90 percent of cases for two decades before 2000.

The cases include 32 defendants sentenced to death. Of those, 14 have been executed or died in prison.

Separately on Monday, the national commission was to hear from Keith Harward, an ex-Navy sailor exonerated last year after serving 33 years of a life sentence for rape and murder in Newport News, Virginia. Harward was convicted after six separate experts including a leader in the field concurred that bite marks on a victim matched his teeth to a “medical certainty.” DNA testing identified a different sailor as the true, lone, perpetrator. No court in the United States has barred bite mark evidence, despite 21 known wrongful convictions, a proposed moratorium in Texas and research showing that experts cannot consistently agree even on whether injuries are caused by human teeth.

The Justice Department and commission’s moves have had impact.

FBI Director James B. Comey last year asked U.S. governors to ask state and local crime labs to review their hair comparison cases, and reviews of past convictions are underway in at least a dozen states, according to the National Association of Criminal Defense Lawyers.

“We want to make sure there aren’t other innocent people in jail based on our work,” Comey wrote in a June letter. “Unfortunately, in a large number of cases, our examiners made statements that went too far in explaining the significance of a hair comparison and could have misled a jury or judge.”

In backing the expanded Justice Department testimony review, then-deputy attorney general Sally Yates said last February that its goal was to determine whether “the same kind of ‘testimonial overstatement’ . . . could have crept into other disciplines.”

“The authority afforded to scientific experts is second to none, and we must make sure that our statements are clearly supported by sound science,” Yates said.

In another example, the Defense Forensic Science Center, formerly called the U.S. Army Criminal Investigation Laboratory, has funded new research establishing error rates for firearms tracking and last month announced it would begin reporting fingerprint results using statistical probabilities instead of declaring one-to-one matches to individuals, a departure from FBI practice.
