Serious concerns about forensic science standards in the UK.

banner_scientist2In England and Wales, since the closure of the Forensic Science Service, forensic testing has been undertaken by a number of private companies. At the time of the privatisation, many warned that introducing a profit-motive into forensic science could have perverse outcomes. Many were concerned about falling standards and ‘bargain basement’ outfits doing shoddy work. Some of these concerns look to have been justified, with news this week that two men have been arrested after the discovery that they have manipulated alcohol/ drug test results used in both the criminal and family courts. The media have reported that almost 500 cases are being reviewed to see if an injustice has occurred. Already, there is one reported instance of a case being dropped because the results of the drug tests cannot be relied upon (First case dropped since forensic science blunders as CPS says it cannot proceed)

While the news of the arrests and falsified rest results have received wide coverage, (see here…. and here… and here…) it comes hot on the heels of a critical report by the Forensic Regulator that iterates that “standards may be at significant risk” (see here. ). The 2016 Annual Report details major failings in the previous year, and warns of the financial pressures that are putting forensic quality at risk, with many police forces still not fully signed-up to minimum standards. Read the report here….    The press release stated that: A lack of funding to improve forensic science is jeopardising the integrity of the criminal justice system. Read the press release here….

With financial pressures on companies, and pressures on workers within those companies to ‘perform’, the risks to forensic science integrity in the UK is obvious. However, it is not limited to the UK and also encompasses all forensic evidence – as concerns grow about the quality of digital forensics in the US as just one example: Bargain Basement Digital Forensics Examiners – Too Good to be True.

The lesson – one that those dealing with wrongful convictions have known for years – is that forensic science cannot be done ‘on the cheap’, and attempting to do so puts the entire legal system in jeopardy.

Precedent-setting hair case drags on

Today marks one year of freedom for George D. Perrot, who served 30 years in prison before his conviction was overturned in a nationally significant case involving flawed FBI forensics and one strand of hair. But Perrot continues to feel “tortured” by Massachusetts prosecutors, who are dragging their feet on an appeal of the decision that set him free. The Schuster Institute for Investigative Journalism updates the case here.

Jeffrey MacDonald actual innocence appeal

Dr. Jeffrey MacDonald, the former Green Beret surgeon who was first cleared in the murders of his pregnant wife and two daughters and then convicted in 1970, will have what may be his final chance at overturning his conviction after spending the past 36 years in prison for a crime that many experts now believe he did not commit.  Oral arguments before a federal appeals court will commence on January 26.  The crime took place prior to the use of DNA analysis and new DNA evidence and a lot of other evidence, including evidence of prosecutorial misconduct, flawed forensic testimony, and botched crime scene analysis, provides powerful support for his story that intruders killed his family in what was in some ways similar to the “Manson family” murders in that same era.  People Magazine investigative reports will culminate in its major cover story, available on newsstands on Friday, January 20.  Here is a link to the People Magazine digital story today that precedes the cover story:

How Janet Reno bolstered the innocence movement

Former U.S. Attorney General Janet Reno was remembered for many things after her death this week. But one of her most important accomplishments was  greatly overlooked — how she fostered the innocence movement. Defense attorney James M. Doyle explains how in a column here.

Junk Science Reigns ____ So Much for True Science in the Courtroom

We had hope, back in 2009, when the National Academy of Sciences report Forensic Science in the United States; A Path Forward was published, that there might finally be some remedy for all the junk science being used to convict innocent people. The report painted a scathing picture of the lack of true science contained in, and the invalidity of, traditional forensic disciplines; the sole exception being DNA. The report did spawn the creation of the Federal Commission on Forensic Science, which has proven, over the last three years, to be a totally toothless tiger, accomplishing essentially nothing.

Now recently, the President’s Council of Advisors on Science and Technology has issued an additional report that is highly condemning of current forensic practices. You can see the PCAST report here:  pcast_forensic_science_report_final

HOWEVER, even in light of this recent report, both the FBI and the Department of Justice have stated they have no intention of changing the way they currently address forensics.

Nothing to Smile About: Bite Mark Evidence Blasted Again

Your smile could cost you your freedom.

Just ask Crystal Weimer from Pennsylvania, or William Richards from California.  Weimer and Richards don’t know each other, but their fates were eerily and tragically similar.

Both were tried and convicted of murder in unrelated cases.  Both of their convictions were based on testimony by so-called bite mark experts, who claimed to have matched marks found on victims with each of the defendant’s “bite mark.”  In both cases, the prosecution relied heavily on the “matching” bite marks as proof of the defendants’ guilt.  In both cases, the bite mark evidence was just plain nonsense.

A new report released this week by the President’s Counsel of Advisors for Science and Technology (PCAST), offered yet another devastating critique of bite mark evidence:

available scientific evidence strongly suggests that [bite mark] examiners not only cannot identify the source of bite mark with reasonable accuracy, they cannot even consistently agree on whether an injury is a human bite mark. For these reasons, PCAST finds that bite mark analysis is far from meeting the scientific standards for foundational validity.

PCAST, an advisory group appointed by the President and made up of the nation’s leading scientists and engineers, suggested that bite mark analysis was unlikely to be “salvageable” as a forensic methodology and that scarce forensic resources should be devoted elsewhere.

The PCAST report adds to the chorus of experts that put bite mark evidence in the junk science category.  In 2009, leading scientists from the National Academy of Sciences issued a report condemning bite mark evidence as highly unreliable.

But despite all the criticism from top-notch forensic experts, bite mark evidence has not been banned from the court room.

Which means that innocent people could wind up in prison for crimes they didn’t commit based on “science” that isn’t scientific at all.

In June, 2016, both Weimer and Richards were exonerated – just one day a part.   As it turns out, the bitemark evidence that put them in prison was just plain wrong.  Collectively, they spent nearly thirty years in prison.

And that is nothing to smile about.

Could Jerry Sandusky be innocent?

What if Jerry Sandusky didn’t do it? Hard to believe, right? The evidence against him seemed to be overwhelming. But was it really?
Author Mark Pendergrast argues that much of the sensational 2012 child-abuse case against the notorious former Penn State assistant football coach hinges on flawed repressed-memory theory. In a commentary for The Crime Report here, Pendergrast says it is relatively easy to generate false memories of abuse and documents how that may have occurred in this case.
