Forensics Canada: Bitemarkers run amok; Courts and DAs prefer case precedence over science.

887a2-snakeoil

This is a 50 page UBC Law Review narrative on the inadequacies of courts to recognize junk “forensic” experts. Battling Canadian bitemarkers leave a trail of exaggerated claims and criminal case law that is blind to scientific principles.

Forensics: Want a BS excuse for “bad forensics”? Blame it on “bad apples.”

Image result for blood letting

This is truly ridiculous counterpoint to forensic science reform, but the forensic industry and its associated prosecutors take it as gospel. The medical profession used claims of “perfection” in the 18th century when they used to bleed patients to death and then kept using the same flawed methods for almost 2 more centuries. Don’t any of these journalists understand the history of science and medicine?

“It’s not the science, it’s who is doing the science,” he said. “These are useful techniques. It’s the people who are doing the work who are overextending themselves. In many cases, they don’t know any better. They don’t know limitations, and they don’t know where to stop. Bite marks are still an incredibly powerful tool. There is nothing wrong with hair analysis.”

“Almost junk forensic science” of blood spatter expertise – Its not as simple as it’s taught in class

More reasons why forensics should not be associated with law enforcement.

FORENSICS and LAW in FOCUS @ CSIDDS | News and Trends

Here is a good look at why “forensics” should be considered amateur-hour non-science in many jurisdictions.

Article goes within a conviction that had the same cop being the crime evidence collector, analyst, and lead investigator. Much goes wrong in the Jennings’ case. The trail of pattern matching over blown conclusions is broad and continues to be acceptable everywhere.

“In the Jennings case, not only did the detective, Nash, reopen the case and serve as lead investigator, he also directly participated in testing evidence in the crime lab.

Nash testified that he was with Jason Wycoff, a DNA specialist with the Highway Patrol, when they tested Jennings’ bathrobe for blood.

According to the trial transcript, Nash said as a “general rule,” the lab did not allow investigators to be present during testing.”

Forensics: regulating junk forensic expertise continues in Texas; other states lagging; from ‘Grits for Breakfast’

Top 10 junk forensic sciences challenged in Texas

In the wake of the Forensic Science Commission declaring blood-spatter evidence in a 30-year old murder case “not accurate or scientifically supported,” Texas has lately again been getting deserved credit as a national leader on forensic reform. Our forensic commission is the best in the country, according to Innocence Project cofounder Peter Neufeld, and our first-of-its-kind junk science writ has made Texas one of only two states (California followed suit) with the means in place to challenge junk science in old convictions through habeas corpus writs.
The most commonly used forensics that were questioned by the National Academy of Sciences 2009 report, “Strengthening Forensic Science: A Path Forward” – like fingerprints or ballistics matching – have yet to face concerted challenges. But quite a few second-tier forensic methods have begun to wilt under scrutiny.

Here’s Grit’s list of the top 10 forensics challenged in Texas to date.

  1. Dog-scent lineups
  2. Outdated arson standards
  3. Hair comparisons
  4. Bite marks
  5. Blood spatter
  6. DNA mixtures
  7. Field tests for narcotics
  8. Future dangerousness testimony
  9. Shaken baby syndrome
  10. Forensichypnosis
  11. Honorable mentionEstimating suspects’ height based on forensic video analysis.
Of these, only dog-scent lineups and flawed arson testimony have been eliminated, with hair comparisons mostly displaced by mitochondrial DNA testing in 21st century cases. A prosecutor in Collin County recently stipulated that bite-mark testimony is junk, so the Court of Criminal Appeals will soon get a chance to declare it non-viable. The rest are under dispute but still in use. Moreover, Texas has yet to figure out how to respond when forensic errors impact large numbers of already-decided cases.

That’s why I’ve said before, Texas may be ahead of other states on forensic reform, but don’t gloat. Most other states are behind because they never left the starting gate, and despite some notable progress, most of our needed forensic reforms remain in front of us.

Forensic tap-dancing at its best

Crime Lab Director Says Too Busy to Search for Forensic Science Errors

Illustration by Bill Hunt

Bruce Houlihan enjoys puzzles, but the Orange County Crime Lab director is purposely failing to solve one of the biggest riddles of his career: Why did his office quietly give conflicting, pro-prosecution, expert testimony in two cold-case, rape/murder trials?

Houlihan met that question—pending at least since 2016, when the Weekly revealed the controversy—with palpable silence until February, when he briefly emerged to deny wrongdoing. Hoping his word would be enough to sidestep an inquiry, he gave no meaningful explanation for his declaration. That misstep only drew additional scrutiny. So Houlihan decided he’d become tight-lipped again, unless commanded otherwise by court order.

Providing irreconcilable inconsistencies in murder cases isn’t the typical bureaucratic snafu. It’s a crisis. Because the overwhelming majority of jurors nationwide have little understanding of forensic-science minutia heard in court, they rely on the credibility of the crime lab officials’ sworn analysis.

But humans we want to trust aren’t always honest. For example, the Massachusetts Supreme Judicial Court reported in 2017 that as many as 21,000 criminal convictions over the years had been tainted by Annie Dookhan, a veteran forensic scientist. While her bosses ignored red flags, Dookhan forged test results, doctored evidence, lied about her misdeeds, wrecked thousands of innocent lives and eventually landed in prison.

In Orange County, our two top law-enforcement officials, District Attorney Tony Rackauckas and Sandra Hutchens—the boss of the Orange County Sheriff’s Department (OCSD)—spent years proving they can’t be trusted either. They’ve allowed deputies to run self-described “cappers,” or unconstitutional scams to help prosecutors win weak cases; hid exculpatory records from defendants; tolerated perjury when uttered by badged individuals; ignored lawfully issued court orders; and operated public-relations campaigns posing as untarnished protectors of justice.

It’s no surprise that Houlihan found allies in Rackauckas and Hutchens. The trio is fighting efforts by Assistant Public Defender Scott Sanders to solve the mystery of People v. Lynn Dean Johnson and People v. Wendell Lemond. How could the crime lab originally declare matching semen-deposit-timing findings at the outset of the 1985 Anaheim cases, denounce those findings as junk science when the cops wanted to nail Johnson in 2008, and then, without announcing their flip-flop on the flip-flop, regurgitate the original findings as gospel to nail Lemond in 2009?

Kevin Haskins, the prosecutor in Johnson, acknowledged the pivotal role the crime lab played. In his closing argument, Haskins urged jurors to abandon any doubts about the testimony of forensic scientists Daniel Gammie and Mary Hong. He argued their brilliance was on par with Galileo and Copernicus. Jurors bought it.

Given that the OC Crime Lab can’t be right in both Johnson and Lemond, you might have expected that a professional outfit would have immediately launched a probe in 2009. But officials did nothing, which is revealing. They weren’t curious to search for cases in which the crime lab’s testimony put innocent people in prison or left actual rapist/murderers on the street.

Sanders said he can explain the lab’s inaction. A legitimate probe would have been (and remains) a messy proposition potentially exposing a terrible truth. The lab altered its scientific opinion in Johnson to help prosecutors, he believes.

Last November, Superior Court Judge Cheri Pham, a former Rackauckas prosecutor, blocked Sanders’ request for a new trial. The public defender is now seeking relief at the California Court of Appeal. He’s facing opposition from Attorney General Xavier Becerra, a Los Angeles Democrat who in May campaigned at OCSD’s Santa Ana headquarters with Hutchens’ Republican-loaded command staff. Becerra claims he’s conducting an independent investigation into the department’s corruption.

Meanwhile, Sanders has also been asking Judge Julian Bailey to force law-enforcement officials and Houlihan to surrender hidden records that may additionally impeach the crime lab on semen-deposit-timing claims. Avery Harrison, a deputy DA, asserted that the task would be too time-consuming to perform. But Bailey began the year seemingly sympathetic with the public defender’s frustration with Houlihan’s stonewalling and refusal to answer questions. In March, the judge signaled that he’d allow Sanders to question the lab director under oath.

But at an April 19 hearing, Bailey—who won a seat on the bench with the endorsements of Rackauckas and members of his homicide unit, which despises Sanders—retreated. Reporters in attendance could feel the shift in attitude. The judge refused to summon Houlihan, who was on-call and a block away. Instead, Bailey reasoned out loud that the defense lawyer should be “satisfied,” at least temporarily, with inspecting the subpoenaed lab records for the period of 1985 to 2008.

In mid-May, Houlihan made Harrison’s prediction come true. He told the judge the hunt for responsive records would be too much of a time burden for the agency. He also asserted he did “not believe that reports after the late 1990s would likely contain any opinion regarding the timing of a semen deposit.”

So, what did the director do? He focused his attention on the records he believed would be least unhelpful to the defense. He prioritized searching electronic records made from 2000 to 2008.

Posing exhausted for a June 6 status report, the lab director declared he’d come up empty-handed. None of the work he’d done found anything responsive, he claimed. With the help of D. Kevin Dunn, his lawyer from the County Counsel’s office, he declared that searching hardcopy files from 1985 to the late 1990s, which are a priority for Sanders, would be a monumental task, an inadvertent admission the lab had never searched for other troubling reports, including those by Gammie and Hong, in a decade. (Gammie now works for a police department in Colorado; Hong runs forensic-sciences labs for the Attorney General.)

At a June 8 hearing, Dunn again pushed to further limit the scope of the defense subpoena. Seven months into the year, Sanders still hasn’t received a single document. He wasn’t happy at the session, repeatedly asking why nobody in law enforcement is concerned whether “bad science” has been used to win wrongful convictions. But Bailey agreed to further delays.

“I don’t see any detriment to [the defense] if I issue an order at this point along the lines that Mr. Dunn has proposed and that would allow some information for [Sanders] to work with,” the judge said.

The public defender looked exasperated. He said to Bailey, “I hope that the court will at least ask [Dunn and Harrington], ‘Aren’t you going to look [to see if you have used equally wrong science in other cases] anyways [without a court order]?’”

The judge refused, a move that must have delighted Rackauckas, his old pal who, at 75-years-old, is hoping he can defeat Supervisor Todd Spitzer in November’s election and grab a sixth-term.

The next stonewalling session in Bailey’s courtroom is set for Aug. 17.

R. Scott Moxley’s award-winning investigative journalism has touched nerves for two decades. An angry congressman threatened to break Moxley’s knee caps. A dirty sheriff promised his critical reporting was irrelevant and then landed in prison. The U.S. House of Representatives debated his work. Federal prosecutors credited his stories for the arrest of a doctor who sold fake medicine to dying patients. Moxley has won Journalist of the Year honors at the Los Angeles Press Club; been named Distinguished Journalist of the Year by the LA Society of Professional Journalists; and hailed by two New York Times Magazine writers for his “herculean job” exposing Southern California law enforcement corruption.

Incompetent Forensics: Using DNA to identify incarcerated immigrant children

Trump’s ICE minions claim detained immigrant records were lost. Others contend they never existed. Massive DNA testing may now insue. Flubber-headed use of forensics by this org is clearly ludicrous.

NIJ Forensics 2018: page 10 deprecates exonerations from criminal convictions aided by unvalidated methods

The US federal look on the forensic issues relating to convictions of innocent defendants is on page 10. Its mostly platitudes and clearly misdirects the reader to consider that stats used by innocence litigators are flawed. The article’s mainstays are, of course, Gould and Collins. For decades they have been the spear-chucking supporters for crime lab orgs praising their accuracies and infallibility. Bitemarks even get some praise. Ridiculous white-wash.
