How best to tell jurors about shortcomings of eyewitness ID

Texas law enforcement agencies must have eyewitness ID policies in place by September 1 of this year which may, but are not required to, follow a "model policy" developed by the Law Enforcement Management Institute of Texas at Sam Houston State University. The Texas Court of Criminal Appeals has said that when police don't follow (an undefined set of) best practices, judges would be guilty of abuse of discretion if they don't allow a defense expert to explain the problems with eyewitness IDs. Even if agencies don't adopt the full model policy, however, and judges allow such experts, Texas statutes and case law mandate no special jury instruction regarding eyewitness testimony. Remarkably, in New Jersey, the Supreme Court recently took it upon itself to issue such a requirement. Reported the New York Times (July 20):
Almost a year after the New Jersey Supreme Court made a sweeping ruling aimed at resolving the "troubling lack of reliability in eyewitness identifications," it issued instructions ... for judges to give jurors to help them better evaluate such evidence in criminal trials.

A judge now must tell jurors before deliberations begin that, for example, stress levels, distance or poor lighting can undercut an eyewitness's ability to make an accurate identification. 

Factors like the time that has elapsed between the commission of a crime and a witness's identification of a suspect or the behavior of a police officer during a lineup can also influence a witness, the new instructions warn.

And in cases involving cross-racial identifications, judges were directed to tell jurors that "research has shown that people may have greater difficulty in accurately identifying members of a different race."

"You should consider whether the fact that the witness and the defendant are not of the same race may have influenced the accuracy of the witness's identification," the instructions say.

The new instructions caution jurors that eyewitness testimony must be scrutinized carefully.

"Human memory is not foolproof," the instructions say. "Research has revealed that human memory is not like a video recording that a witness need only replay to remember what happened. Memory is far more complex."

The new instructions, which take effect on Sept. 4, address the problems the State Supreme Court identified last August in a unanimous ruling that concluded that the traditional test for reliability of eyewitness testimony, which the United States Supreme Court set out in 1977, was outdated and should be revised.

Although it applies only in New Jersey, the ruling was widely heralded for containing the most exhaustive review of decades of scientific research on eyewitness identification.

The new instructions are expected to be influential as other state courts look to revise their approach to eyewitness identification, several legal experts said. 
Erroneous eyewitness testimony has been by far the most common cause of false convictions among DNA exonerees and these instructions go a long way toward reducing the chance of false convictions. Though falling short of requiring corroboration of eyewitness testimony - which Grits thinks is justified when the witness had never previously seen the defendant - these sorts of cautions go a long way toward rebutting false assumptions by jurors which have contributed to so many high-profile miscarriages of justice.

The New Jersey jury caution could have implications for Texas courts as well. The Court of Criminal Appeals cited the New Jersey ruling in their own landmark eyewitness ID case last year, State v. Tillman. The Tillman case said judges abuse their discretion if they don't allow expert witnesses to educate jurors when police fail to follow best practices, but the ruling did not identify in detail just what those best practices are. Arguably the SHSU model policy provides significant guidance, but the New Jersey rulings provide an especially strong basis for making such a judgment.

Ironically, Texas' statute was designed to give more deference to law enforcement, but the Tillman case means when proper procedures aren't followed, counties must pony up (in indigent cases) for a defense expert. By contrast, New Jersey's approach informs the jury of essentially the same limitations on eyewitness testimony without having to pay for additional expert testimony. Despite the Texas Legislature's intention to cater to law enforcement by not including a jury instruction, New Jersey's approach - creating a hard and fast rule - would probably be simpler for police, prosecutors and jurors alike.

SHSU crime lab abruptly shuttered, Fort Worth PD looks to re-open DNA section a decade after failures

The loss of a new fee for service crime lab run by Sam Houston State in Montgromery County will put more pressure on the Department of Public Safety crime labs ad possibly add to their already too-long wait times. Reported the Conroe Courier:
The loss of the Sam Houston State University Regional Crime Lab, which opened in November 2010 in The Woodlands, will mean significant delays for results in testing evidence such as blood-alcohol and toxicology tests, said Assistant District Attorney Warren Diepraam, chief of the Vehicular Crimes Division for the Montgomery County District Attorney’s Office.
The crime lab will lose its current home in September because the landlord has found another tenant, said Dr. Vincent Webb, dean of the College of Criminal Justice at SHSU in Huntsville and director of the university’s Criminal Justice Center. ...

With the loss of the SHSU crime lab – which serves more than 70 agencies – Montgomery County now will have to send tests to a Texas Department of Public Safety Regional Crime Lab in Austin, which serves many more clients, Diepraam said.“With the Regional Crime Lab, we got results in a week or two,” he said. “Unfortunately, the DPS lab has a backlog of cases. For drug toxicology tests, it could take six to nine months to get results. That’s a concern to the district attorney that we’ll have people staying in jail while we’re waiting on results.”

From November 2010 to October 2011, the Regional Crime Lab ran 1,034 drug toxicology tests, with 900 of those from Montgomery County, Diepraam previously said. During that same time period, the lab analyzed 4,335 controlled substance evidence items, with 86 percent of them coming from Montgomery County, according to a casework overview by the lab.
Conversely, the Fort Worth PD crime lab hopes to expand capacity in its lab for DNA work, reported the Star-Telegram, after shutting down a decade ago "amid backlogs and accusations of shoddy work and contamination."
The lab's two forensic scientists will begin working cases Monday, crime lab Director Tom Stimpson said Thursday. With the training of three other scientists at least six months away, Stimpson said, he hopes that the Police Department can stop outsourcing most DNA testing within a year.
"The benefit to the department for us really is going to be the turnaround time and the selection of what we can test," Stimpson said. "Now we're in full control of our evidence. We can test what we want and when we want it."

And the savings, he said, will be significant.

Grants cover some testing by the University of North Texas, but the Police Department must pay roughly $250,000 a year to Orchid Cellmark, a Dallas-based company, for other analyses, he said.

Putting a rush on a DNA order costs even more. "With Orchid, because they're a business, we were paying them a premium of about $500 a sample over and above what the regular cost was to have something done within a week or 15 days," Stimpson said.

An in-house DNA unit will also save money for the entire Police Department, because a faster turnaround can mean quicker arrests, he said.
Since Fort Worth was contracting with a private provider for DNA services, their new lab won't take any pressure off DPS' caseload, at least directly, but it will add to the state's overall lab capacity once it opens.
