The reason there is no change

If MDs resist this science-only reform movement battling decades of a “believe system” of opinion then their own training is suspect.

mbhauptle's avatarEye of the beholder

Forensic Pathologists trust bitemark pattern injury analysis, and want to use it at their discretion, even if its use becomes passé in identifying the perpetrator. The word is out that they think eradication of bitemarks is the pendulum swinging too far in the opposite direction.

I can understand this. Their thinking is if you can tell from a bitemark in skin that the person, the biter, was missing a tooth, then you have assisted the cause of criminal justice. But, it confuses me.

To date, it is not common practice to “age” a contusion in skin, in order to establish post mortem interval. It’s not common practice to measure the depth of a sharp force injury in flesh, be it a stab wound or incised wound made with a knife. I still think determining the directionality of a knife wound across the neck is not feasible scientifically, either.

However, I…

The Junk Science of Bite Marks Needs to Go Away

Phil Locke's avatarWrongful Convictions Blog

We’ve posted about bite mark junk science here before. See About Bite Mark Evidence – Forensic Odontology.

Now, a leading White House science advisor has exhorted the National Institute of Standards and Technology (NIST) to eliminate bite mark evidence, because there is, in fact, no science to it at all. See Radley Balko’s recent article in the Washington Post here.

Balko also correctly advocates in his article that we MUST get trial court judges out of the business of being the decision makers about what is, or is not, valid science. “If not a single court in the country to date has been able to rule against a self-evidently absurd field like bite mark matching, why should we continue to entrust the courts to arbitrate the scientific validity of other evidence?

Federal judge opinion about “experts peddling junk science to credulous judges and jurors”…..

This federal court (from the Chicago area) opinion speaks to how people  exonerated of serious crimes have little legal recourse (having no state statutes and judicial case law privileges or right to sue most government “actors.”) for recompense for damages caused by experts’ opinions brought forth by prosecutors during their original trial. The judge states much the same here, while saying that exoneree Bennie Starks was “a victim of injustice.” In denying most of Starks’ lawsuit, he sounds almost regretful about the legal outcome. The full opinion.

Part of  Bennie Starks Illinois federal civil suit claimed that the then DA’s  2 bitemark experts had personal liability as they were associated with his wrongful conviction in 1986. They have never repudiated their original opinion despite disagreeing colleagues reports, depositions, and DNA results from the crime victim that did not match Bennie Starks.

Other commentators in the media have expressed some interesting responses:

Radley Balko at the Washington Post states on @radleybalko : “Federal judge: Bite mark matching is fraudulent, but analysts who helped convict an innocent man still aren’t liable.”

Dan Hinkle at the Chicago Tribune says the case will continue to a August 17 trial on the remaining claims against Waukegan police.  He continues with the fact that “Lake County has a history of bungling major criminal cases, and that Starks is one of six men from the jurisdiction cleared by DNA or medical evidence in recent years.”

The 2 dentists’  attorney stated that they “should never have been sued”, as their testimony was “offering opinions” and the dentists are “still highly respected.”

Starks’ attorney plans to appeal.

More from the judge. 

But Federal Judge Feinerman’s conclusion summarizes contents within his final opinion that attack the use of bitemark matching in courtrooms. He cites similar findings from the National Academy of Sciences 2009 “Strengthening Forensic Sciences” report , legal commentaries and new research from the University of Buffalo as substantive support for this opinion.  Then also adds “motivational bias” and false claims of scientific validity to this list.  The part about bitemark pattern matching flaws  starts on page 20.

Then he finishes with:

“The criminal justice system occasionally delivers injustice, and Starks appears to have been the victim of “experts peddling junk science to credulous judges and jurors” and “it is easy to sympathize with Starks’s plight.”

Judge Feinerman plans to keep an eye on what happens in the upcoming Starks’ trial (using claims he did not deny)  against the city of Waukegan.

The National Registry of Exons. When convictions go wrong, the price in human suffering can’t be ignored

 

Read this excerpt first…..

“The registry receives four or five letters a week from prisoners who claim to be innocent. They’re heartbreaking. Most of the writers are probably guilty, but some undoubtedly are not. We tell them that we can’t help; we are a research project only, we don’t represent clients or investigate claims of innocence. Fair enough, I guess, but some innocent prisoners who have been exonerated wrote hundreds of these letters before anybody took notice. How many innocent defendants have I ignored?”

The staggering number of wrongful convictions in America

July 24

Samuel R. Gross, a law professor at the University of Michigan, is the editor of the National Registry of Exonerations.

I edit the National Registry of Exonerations, which compiles stories and data about people who were convicted of crimes in the United States and later exonerated. The cases are fascinating and important, but they wear on me: So many of them are stories of destruction and defeat.

US Forensic Odontology Program to provide debunked ABFO bitemark training?

More on the UT Knoxville Forensic Anthro program which could give the upstarting UT Forensic Odontology program a big scientific boost. http://fac.utk.edu/

This dissemination of debunked bitemark techniques includes other “short course” programs put on by either the abfo itself during annual AAFS meetings or places like LSU, and UTexas in San Antonio. Curriculum transparency and best practices are paramount in forensics.

Someone at the University of Tennessee needs to rethink this odontology curriculum. I’m sure that the non-ABFO faculty affiliated with this forensic dentistry program at UT haven’t a clue about what is going on about bitemarks. UT has a tremendous reputation for its Forensic Anthropology department’s development of its “Body Farm” originated by Emeritus Professor Bill Bass and ongoing research in human identification.

After all the flack and criticism in the scientific and legal communities about bitemarks, this course of study (sponsored by its AG dept) is described as the  “first of its kind in the US” via a 34 unit MS program in forensic odontology. The human body ID subject matter section should be exemplary for the students. The bitemark sections will be a rendition of the “elite” ABFO’s “science” or “non-science” (it varies among its few vocal members) which the White House Office of…

Forensics: A BIG dust up in AUSTRALIA over 400 opines of a state Medical Examiner

This all started with a recent judicial (last year) opinion on a 20 year-old case dealing with “murder in a bathtub.” The government’s path guy, Dr. Colin Manock, got clobbered in a book about this case and which seems to have brought to light “a miscarriage of justice” and “doubt” an “unreleased evidence ” assertions by a presiding justice.

Chilling words for any forensic expert. Apparently in the US, the justices of MS may get a chance of their own in the Howard case recently argued by the MS Innocence Project’s Tucker Carringtion. In the past, the target expert, dentist Michael West, had the court (with a different membership) rule that his “being wrong in one case, did not ” make another case of his suspect. So far, West has had four convictions overturned, in entirety or in part, by his brand of “ipse dixit” “I am a doctor” testimony.

The MS Supreme Court also showed some reasonableness by admitting junk forensic science actually exists.

The bitemark sections will be a rendition of the “elite” ABFO’s “science” or “non-science” (it varies among its few vocal members) which the White House Office of Sci and Tech researcher now considers worthy of “eradication.”

Both program dentists are ABFO members, one of whom has criticized of the University of Buffalo’s groundbreaking odontology research. The 2 recommended odontology texts are from a bunch of ABFOers who publicly continue to scoff at the NAS 2009, ignore their own failed attempts at reliability testing, can’t validate what they do and so on.

A quote: ” The course of study is founded on the standards and guidelines established by the American Board of Forensic Odontology.” Oops.

Caveat Emptor. Too bad the world famous Anthropology department at UT isn’t in charge. Anthros LOVE research data to support their investigations. Dentists are less inclined.

Here is their PR statement:

Description, Scope, & Purpose

“The Forensic Odontology MS degree concentration in Comparative and Experimental Medicine is the first master’s degree of its kind in the United States. The course of study is founded on the standards and guidelines established by the American Board of Forensic Odontology (emphasis added) in the endeavors of human identification, bite mark investigation and analysis, dental age estimation, missing and unidentified persons, and mass fatality incident dental identification team
development.”

 

At the very bottom is this statement about the courses target audience: “……..and others wishing introduction and formalization of skills in the search, recovery, and collaborative identification of compromised human head and neck remains, and recognition (emphasis added) of human and non-human bite marks at autopsy.’

Could there be a sea change within the ABFO connected to this? As in teaching “bitemark” recognition and leaving the aforementioned “bitemark analysis” part out? Too bad the recent ABFO recognition testing proved to be a failure.
