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: The Junk Science Cops Use to Decide You’re Lying
Leaked documents detail law enforcement trainings in lie detection techniques that have been discredited by scientists.

Forensics India: Bitemarks In The Dock: The Questions We Are Not Asking
The article restates what has been done in the US debunking bitemarkers and recommends adoption of same in India. Also, the author says many Indian courts and prosectors still demand bitemark pattern evidence continue to be used. This is similar to the US National Association of Medical Examiners ( theNAME.org ) demanding employment of bitemarkers dentists for ME facilities to achieve its “accreditation.”
Indian courts should urgently take notice of the scientific research into the validity and reliability of several forensic disciplines

Forensics: A British AI Tool to Predict Violent Crime Is Too Flawed to Use
The insidious creep of junk forensics. Much like US medical examiners being forced to hire ABFO bitemarkers in order to be certified by TheName.org
A government-funded system known as Most Serious Violence was built to predict first offenses but turned out to be wildly inaccurate.

Forensics: St. Louis prosecutor instructed crime lab experts to reassemble Patricia McCloskey’s gun
This is about a husband and wife brandishing weapons at BLM protesters walking past their mansion. Their def atty says the wife’s gun was inoperative and now claims it has been tainted by the DA. Dad had an assault rifle and at one point had it aimed at her head. Brilliant.
A St. Louis prosecutor ordered Patricia McCloskey’s gun to be dismantled and reassembled, noting that it was “readily capable of lethal use” in charging documents.

Forensics: A comparison of proteomic, genomic, and osteological methods of archaeological sex estimation
Very obvious as to who wins this contest. Bones at the bottom.
Sex estimation of skeletons is fundamental to many archaeological studies. Currently, three approaches are available to estimate sex–osteology, genomics, or proteomics, but little is known about the relative reliability of these methods in applied settings. We present matching osteological, shotgun-genomic, and proteomic data to estimate the sex of 55 individuals, each with an independent radiocarbon date between 2,440 and 100 cal BP, from two ancestral Ohlone sites in Central California. Sex estimation was possible in 100% of this burial sample using proteomics, in 91% using genomics, and in 51% using osteology. Agreement between the methods was high, however conflicts did occur. Genomic sex estimates were 100% consistent with proteomic and osteological estimates when DNA reads were above 100,000 total sequences. However, more than half the samples had DNA read numbers below this threshold, producing high rates of conflict with osteological and proteomic data where nine out of twenty conditional DNA sex estimates conflicted with proteomics. While the DNA signal decreased by an order of magnitude in the older burial samples, there was no decrease in proteomic signal. We conclude that proteomics provides an important complement to osteological and shotgun-genomic sex estimation.
