6th Circuit US Court of Appeals rules in US v. Carpenter that the government did not violate defendants’ Fourth Amendment rights by collecting cell site records from robbery suspects without warrants. Regarding the court’s opinion, one spokesperson for the ACLU stated: “The majority’s opinion unfortunately fails to adequately account for the privacy violations made possible by the cell phones that we all need to carry around to live our lives normally…Comprehensive location tracking like this requires robust Fourth Amendment protections.” (ABA Journal)

NY state senate proposes legislation allowing law enforcement to use “textalyzer” devices on drivers suspected of using their phones before automobile accidents to determine if they were “unlawfully driving while distracted.” The new legislation would require individuals to hand over their phones to be searched or face driver’s license suspension—and driving with a suspension due to failure to submit to the “textalyzer” will be a new misdemeanor. The legislation has already passed the state assembly and state senate (Ars Technica)

Forensics: Pattern injuries in Pistorius case brings out some amateur sleuthing

No surprise here because, back in the Pistorius trial days, I thot nothing could match it (discounting Amanda Knox’s years of uncertainty) in recent history, but then “Making a Murder” jumped onto the silver screen (well, its a LCD screen these days)

With Pistorius facing new sentencing penalties in South Africa, a couple brothers are doing some CSI type speculations about skin injuries on Reeva Steenkamp’s body. Here we go. They appear to be able to “time” these injuries to “before” the shooting occurred. Hmmm

“The Molletts have just published their third book, Oscar vs The Truth (Piquet Publishers) and have drawn several shocking conclusions in relation to Reeva’s murder, including that two oval abrasions that were found on her back appeared to match the corner of the Lazer bat Pistorius said he had used to bash down the door after shooting.”

The nature of DNA exonerations are changing

The National Registry of Exonerations just published data on the various crime types of cases where exonerations occur.

DNA exonerations no longer occur primarily in rape cases, but in homicides, including many rape-murder cases.

In addition, the number of DNA exonerations in which non-DNA evidence was necessary for the exoneration is approaching the number where DNA alone conclusively proved innocence.

 

All told, rape is an element in 78% of known DNA exonerations (329/420). In that context, the shift since 2008 mostly means that DNA exonerations are increasingly about rape-murder rather than rape alone

Forensics: Looking at attempts to age fingerprints in US court cases – FSI Journal

Meet “Freddie the Fingerprint”

Reviewing the actual courtroom testimony of forensic experts is clearly the way to suggest “reforms” and to publish how examiners approach their “science” in diverse ways.

Sound familiar? Pathology. Bitemarks.

An interesting look at what goes on in the US courts about fingerprints. Authors have some compelling concerns:

  • •Numerous court cases show disparities in the management of fingermark dating issues.
  • •This lack of consensus is due to the absence of a validated fingermark dating method.
  • •Research about fingermark dating is on going and some approaches show promise.
  • •Based on these approaches, a methodological framework for dating issues is proposed.
  • •Data from cases and research should interact to develop a relevant dating methodology.

Abstract

The question of the age of fingermarks is often raised in investigations and trials when suspects admit that they have left their fingermarks at a crime scene but allege that the contact occurred at a different time than the crime and for legal reasons. In the first part of this review article, examples from American appellate court cases will be used to demonstrate that there is a lack of consensus among American courts regarding the admissibility and weight of testimony from expert witnesses who provide opinions about the age of fingermarks. Of course, these issues are not only encountered in America but have also been reported elsewhere, for example in Europe. The disparity in the way fingermark dating cases were managed in these examples is probably due to the fact that no methodology has been validated and accepted by the forensic science community so far. The second part of this review article summarizes the studies reported on fingermark dating in the literature and highlights the fact that most proposed methodologies still suffer from limitations preventing their use in practice. Nevertheless, several approaches based on the evolution of aging parameters detected in fingermark residue over time appear to show promise for the fingermark dating field. Based on these approaches, the definition of a formal methodological framework for fingermark dating cases is proposed in order to produce relevant temporal information. This framework identifies which type of information could and should be obtained about fingermark aging and what developments are still required to scientifically address dating issues.

Better news from within the American Brd of Forensic Odontology bitemark scandal

 

This is a short story but its carries an important metaphor about the “forensic science “reform” process rocketing through the media and courtrooms in the US and the UK.

A pertinent question I have is “how does the our legal system recognize that science within its confines is constantly changing and how does the Criminal Justice system adapt to issues of junk and questionable testimony from generally law enforcement prone experts?”

Its a mouthful, but “change within the court system” does not seem similar to dynamic change in other aspects of our social melieu as we experiences changes of  consumer products, air bags, public health, health care, pharmaceuticals, pollution and ecosystem change. Answers or solutions to all these are commonly threaded with established legal oversight, or threats of regulatory control, or actual consumer law litigation by state and federal police agencies. However, legal institutions and agencies are not proactive, but reactive in addressing things that have already happened. To be exact, the government is usually NOT a first responder to public safety and Constitutional issues within criminal justice.

At this point, our legal systems are largely unprepared to handle the upcoming onslaught of appellate litigation regarding flawed and unreliable  expert testimony. Science is improving but some prosecutors, Attorneys General and state courts are still driving a Model T.

Back to forensics.

Who has been proactive within forensic science and asking for more bases of science within the “police sciences?” A small group from within these disciplines does exist. At the forefront were a few prominent whistleblowers who started getting notice 30 years ago regarding major FBI Crime lab goofs.  There were also other forensic examiners who learned some science and began to understand how prominent DNA would become. A few others since, although they may still be isolated from any consensus within their subject matter groups, have become vocal and  volunteer to innocence projects (IP Network) across the US.

Some other change has occurred. Since the 2009 NAS Report on forensics, the professional meetings I have attended now contain talk about wrongful convictions as a fact, rather than just some crank accusations from money-grubbing lawyers (no exaggeration ). But, in the  AAFS odontology (Dentistry) section, I apparently am the only experienced forensic dental type who talks about actual cases as showing systemic problems, but at least that’s a start.

A good example of people taking a hard look at their forensic methods are some members of the American Board of Forensic Odontology who are active in IP criminal litigation objecting to past use of bitemark pattern “identification” in prosecutions for the last 50 years. This tiny bunch (out of hundreds of self-proscribed forensic dentists in the US) take on cases which have become headline news in the exoneration world. It takes some courage to do this as many to all of these post-conviction bitemark cases (its up to 25 total) were prosecuted and helped by the “big guns” in bitemarks who were at their height of public crime fighting glory. I also have to give credit to those dentists (about 3 or 4) who have recanted their years-old testimony. That takes alot of guts. Some of them have said their “science” has improved. I don’t think that is accurate (there wasn’t any science to begin with), but it sure sounds good to most people and the courts.

So, I am giving credit where its due, as the ABFO is becoming incrementally more involved with wrongful convictions via these members who are stepping up. This is despite the group’s past leadership’s traits of dirty dealing towards those who have objected to their intransigent ways.

More problems with the US Medical Examiners System – Underfunding

Death investigation within Medical Examiner/Coroner system has always been the most underfunded in the Law Enforcement Organization (LEO) systems. The numbers of boarded med path people is seriously declining. Working in such conditions certainly does not create much enthusiasm despite the high-tech fantasies of CSI shows. The incongruity of how important these investigations are to police and prosecutors “fighting crime” is striking.

Here is the mess that going on in Los Angeles.

Forensics: Forensic Pathology study on skin injury patterns shows lack of agreement

Published in the Apr 15 2016 Journal of Forensic Sciences, this paper are the results of a NAME (US medical examiners) online study of human skin injury pattern diagnostic categories ( the basics of “blunt,” “sharp,” and “source” identification) undertaken by some of its members.  It’s significantly better than the bitemark group’s testing of bitemark patterns.”

Remember though, that the forensic contexts are different. Sharp vs blunt disagreement does not lead to a mis-identification of a innocent defendant.

One also might wonder what other patterns “patterns” where these folks don’t strongly agree. There are diagnostic patterns in Shaken Baby Syndrome, called the SBS “triad” that are at the center of a raging debate in and out of courtrooms and the media.

Get a.pdf of Forensic Pathologist Consensus in the Interpretation of Photographs of Patterned Injuries of the Skin here.

Abstract

Forensic pathologists are commonly asked to evaluate injuries on the basis of photographs. Members of the National Association of Medical Examiners were asked to participate in an online survey in which they were presented with 68 patterned injuries of the skin and asked to make a diagnosis ranging from very general (e.g., “blunt” vs. “sharp”) to specific (e.g., “baton blow”). This was not the case. Consensus for general diagnosis averaged 0.77 and 0.72 for specific diagnosis. While there was a strong correlation between consensus and confidence in aggregate, individual correlations were poor. Consensus diagnosis was inversely correlated with age, and positively correlated with jurisdictional size, medical degree, and whether or not the respondent was actively performing autopsies as a job function. A subsequent survey is exploring possible reasons for lack of consensus in low-consensus questions. The high correlation between confidence and consensus at the aggregate level and low correlation at the individual level may have implications for quality assurance protocols.

The American Dental Association needs to act on members still practicing bitemarks

Most of the US bitemark group, the American Board of Forensic Odontology, are also members of the ADA. In fact some of the ABFO are “vaunted” as fighting crime through their “success” in criminal court convictions.  Here’s a 2015 link to a California dental journal exceeding praiseworthy of the bitemark crew.

So far “”success” has resulted in 25 innocent men being convicted. Keith Allen Harward being the latest.

“The Innocence Project hopes Harward’s exoneration leads to a national review of old bite-mark cases comparable to one underway by the FBI, the National Association of Criminal Defense Lawyers and others of old microscopic hair analysis, another forensic technique that has contributed to wrongful convictions.

A similar bite-mark effort, however, would require support of forensic dentists, also known as forensic odontologists. So far, that support has been missing.”

The latest bitemark exoneration in VA raises the issue of what to do with other bitemark convictions

This editorial article speaks volumes about the the damage done to one man ( in his own words) and expands public concern about other criminal defendants in our Criminal Justice system during the 50 years of “judicially accepted” bitemark opinions aiding convictions.

This VA Harward case is the 25 exon victory litigated by the NY Innocence Project and local defense counsels which overcame prosecution experts certified by the American Board of Forensic Odontology.

The ABFO’s current president, Dr. Adam Freeman, has publicly stated that his org has “a responsibility” to review all its members’ casework.

From my experience as a past member of this group (1989 – 2011), the number of bitemark cases that needing review exceed one thousand.

So, ABFO, what is your next step? I know that some members have warned the membership that any efforts at critiquing their casework will bring consequences.

Here is what the Innocence Blog has to say about the Harward case.

The Fredericksburg Free Lance Star ran an editorial Friday urging Virginia courts to show more skepticism with regard to bite mark evidence in criminal cases.

Using the recent exoneration of Innocence Project client Keith Harward as an example, the editorial board cautioned courts in the state to consider the proven unreliability of bite marks as evidence.

Harward was released and exonerated last week after spending 33 years in prison for a rape and murder, which DNA evidence proves he did not commit. Harward was convicted primarily on the testimony of two forensic dentists who said that Harward’s teeth matched marks left on the rape victim.

“If the courts were to show more skepticism about bite-mark evidence, they would find allies in the very organization that accredits and certifies forensic odontologists,” writes the editorial board. Recent exonerations such as Harward’s have led the American Board of Forensic Odontology to issue new guidelines regarding expert testimony on bite mark evidence.

“The courts should show at least as much concern about the evidence as the board that accredits the experts,” the editorial board wrote.
