NY County Prosecutor accused of doing the dirty deed in 15 drug cases

Image result for withholding evidence

This looks bad in the press and I bet the judge won’t be happy either. Withholding evidence in 15 cases?

excerpt from Syracuse, Cayuga county, NY.

AUBURN, N.Y. – Tyrone Matthews could’ve been sentenced to 23 more years in prison than his case warranted.

He was charged as a drug dealer, not as the guy who brought the dealer and buyer together.

His role as a go-between was spelled out in a police report that was not initially turned over to Matthews’ lawyer.

Under the law, a prosecutor has to give accused criminals any evidence that they can use in their defense.

The former assistant Cayuga County district attorney who initially handled Matthews’ case told the defense lawyer about the undisclosed police report in January. A judge later ordered the district attorney, Jon Budelmann, to turn it over.

News release: STRmix allows defense attorneys access to their source code

The writer on this blog post , John Buckleton provides interesting and valuable details regarding additional information on peer review and judicial acceptance of this DNA software.  He is a co-developer of STRmix, a NZ government employee and has  stated to me his no financial interest in the product. Cheers to John and his colleagues.

Quoting an erroneous story in Buzzfeed News from earlier this year, your recent article incorrectly states, “The main problem with STRmix and other DNA-matching software programs is that hardly anyone knows how they work.” While we are not in a position to discuss other DNA software, numerous scientific papers focused on the STRmix™ formulae have been published in peer-reviewed scientific journals in order to ensure robust scrutiny and acceptance by the scientific community. In addition, four-day training workshops routinely are conducted for STRmix™ users before they implement it to ensure that they understand how STRmix™ works and are able to correctly represent the results it generates in court. 

 

STRmix™ has a policy that allows defense scientists access to STRmix™ source code and an executable version as long as they are not developers of competing software. Further, we have trained defense and prosecution forensic scientists in the use of STRmix™ and remain open to additional ways we can help the legal community to understand STRmix™.  

 

While STRmix is indeed a relatively new technology, it has been used to interpret DNA evidence in literally thousands of cases for more than four years. In the U.S., there have been three successful admissibility hearings for STRmix™, while DNA evidence interpreted with STRmix™ has been successfully used in more than 65 other court cases.

 

We hope this helps to clarify the use and acceptance of STRmix and we ask you to publish this correction for your readers.

 

Warmest regards,

John

NIST (US government science and tech forensic researcher and funder) announces a new look into the physical world of properties’ “stick” and “strain.”

“the mechanical properties of four types of evidence: hair, documents, fingerprints and explosives.”

Gun crime labs micro-critique of the PCAST report

Image result for afte toolmark

The Association of Firearm and Toolmarkers [AFTE] focus on defending ballistic matching via alluding “black-box” studies (one of PCAST’s references) are not representative of the entire group. They also point to in-house reliability testing as a substitute. Overall, this public statement is much more measured than what’s come out of the District Attorneys and US DOJ /FBI but is similar in its effect that all their research and foundational studies are sufficient. Here’s an interesting excuse about funding, which hardly moots what forensic issues which includes the unmentionable: wrongful convictions.

“It is true that the majority of past research has been conducted by AFTE members, because while DNA and fingerprints have applications outside of forensics (such as medicine and biometrics), firearm identification has few profit-making applications and does not garner research attention from the private sector.”

Jury looking at exaggerated forensic opinions – a strong bias results

Image result for keep it simple

A law prof tries a simple way to explain what PCAST is concerned about. He also includes the following: [Brandon Garrett at Va. Law’s Faculty Q&A]

Few studies had been done examining how jurors appreciate some of the most commonly used forensics, including fingerprint evidence. [UVA Law professor] Greg Mitchell and I embarked several years ago on a series of studies, and what we discovered surprised me: I expected that we would find that when analysts gave conclusions exaggerating their certainty that prints came from a defendant, that jurors would place more weight on the evidence. Jurors were not overly affected by those over-statements. Instead it seemed as if just hearing the word “fingerprint” was enough to convince jurors that the defendant did it. In more hopeful news, though, we discovered in a second experiment that jurors were affected by hearing that there is a possibility of an error in fingerprinting. Still more promising, in a detailed follow-up experiment, we are exploring how jurors can be highly sensitive to information about the error rates, or the proficiency, of the particular fingerprint examiner. We plan to do more to explore these findings and make practical recommendations for testimony, reports and regulation of forensics in the courtroom.

Canadian wrongful conviction file totals 85 – funding diminishing

Innocence Canada struggling for funding for wrongfully convicted cases

‘I’m always frustrated with how long it takes us to do cases, in any event, but this is going to slow us down even more.’

A Newfoundland man who helps free the wrongfully convicted says his organization is struggling to find funding and could be in jeopardy.

Ronald Dalton was convicted of murdering his wife in 1989 and spent eight years in prison before he was found not guilty in 2000. Now, Dalton is the co-president of Innocence Canada.

He said with less money, the organization will struggle to review cases efficiently and help those who need it.

Ballistics on the hot seat as being “too subjective” in final opinions

Image result for gun matching cartoon

The premise in ballistics is that all these casings might be considered “unique.”

This  “new look” at ballistics from the Aaron Hernandez conviction is similar to the back and forth decades-long argument against the now debunked “hair matching” in four areas:

  1. Identifying people and objects to a single source. either being a specific gun or person.
  2. Both have been forensic “workhorses” for the FBI and their progeny in US police crime labs.
  3. Police crime lab communities stands fast that all is “well.”
  4. Final decision-making usually falls on non-science trained judges and lawyers to decide what threshold of proof are sufficient for our justice systems.

excerpt from the Boston Globe:

The scrutiny now includes the field of firearms analysis, often called ballistics, after a report last month by the President’s Council of Advisors on Science and Technology questioned whether the science of analyzing firearms is sound enough to support the standard of proof that is constitutionally required for a criminal conviction.

The report has already sent ripples throughout legal and law enforcement communities, including in Massachusetts, as lawyers in one of the state’s most high-profile cases – the Suffolk County murder trial of former New England Patriots player Aaron Hernandez – asked a judge earlier this month to toss expert testimony related to a firearm police have linked to the case.

Bad forensic testing and testimony is no problem for this DA

Image result for district attorney obstinate

A successful re-trial motion for a convicted murderer is getting a W.Va. DA to use his right of appeal. Making no inroads in the prosecutorial pantheon of notable literature, the DA says the original conviction was “finalized” in 1988. Full article from the Herald-Dispatch

Sidebar about W.Va.: http://www.theintelligencer.net/opinion/editorials/2016/09/reduce-rape-kit-testing-backlog/ ( the article covers hundreds of rape kits being untested by law enforcement authorities in the state.)

This West Virginia DA is using a popular metaphor we can translate as: “once convicted always guilty” despite the judge agreeing that flawed forensics brought by a long-discredited expert created an unfair result to the original trial. California’s Attorney General and the aspiring-to-Attorney-General DA Michael Ramos (campaigning pic above) used some similar legal boilerplate in appealing Bill Richard’s exoneration in 2009. His appeal questioned  and argued against the Superior Court’s “jurisdiction” disallowing it to preside and rule on Richards’ habeas corpus motion. Ramos’ appeal brought a trip to the CA Supreme Court in 2012 where its ruling in favor of Ramos was considered “the worst opinion of the year.’

On to 2014 where the creation of a California forensic science “junk’ statute eventually brought Richards his freedom early this year. In 2016,  a reconstituted SC agreed that a “grandfather of bitemark experts” recanting statement at the ’09 exoneration hearing was more than sufficient to vacate/reverse the 1997 conviction.

Through all this overriding Ramos’ manuevering, he continued sniping and public assertions of more vigorous prosecuting adventures against Richards.  

The state of W.Va is using the same playbook as Ramos.

Forensic Bias Redux: Execution vacated. Internal crime lab safeguards blew it.

Image result for expert testimony cartoon

Colleagues had doubts and concerns. The cops and supervisors loved her work. She admits to be a bit histrionic in and out of the job. The state’s AG has no concerns. Recently the governor and one judge pulled back from sugar-coating her “impression-matching” credibility. The gov took one inmate off death row 13 days before execution. Add a noted impression evidence guru using the dreaded “sub-standard” term.

Another example of how police controlled crime labs, medical examiners and police-shooting commissions need to be independent and properly vetted against undue influences. Serious disputes arise from LEOs at the mere suggestion. For example, independence didn’t work so well at the DC crime lab when politicians and law enforcement recently sucked it back up into their pockets. Then came: New DC Crime lab management, mayor and DA adopt measures their previously fired director were denied

Here is the latest on this BCI crime labber’s version  of forensic “justice.”

So, is the PCAST forensics report still bunkum as stated by the National District Attorneys Association?
