The headline was simple – another person exonerated in a case where police claim he had confessed and where two eyewitnesses positively identified him. But absent from the story was any mention of DNA as the exculpating tool. Instead, it was reported as follows: The experts reviewed surveillance footage of the botched heist of Northeast
The waning days of the Trump administration saw a fervid, if not frenzied, rush to put out policy statement or decisions meant to tie the hands of the Biden administration, including declaring Cuba a state sponsor of terrorism, labeling a Yemeni group a terrorist organization, recognizing Moroccan sovereignty over parts of the Sahara, allowing oil
Lawyers fight tooth and nail over whether a particular statement is admissible hearsay – is it an assertion; if so, is it offered for its truth; and if both conditions are met, is there a hearsay exception that permits it to be heard or seen. And then they stop. But as a recent Pennsylvania Superior
Given that the Rules of Evidence were developed without regard to, or prior to the development of, principles of cognitive science, one might expect courts to use scientific research to mediate those rules and, especially, to inform the exercise of discretion. But as two divergent lines of cases show, although each involves how a visual
INTRODUCTION: This author was recently asked to submit a DECLARATION affidavit as to whether the science of perception, memory and recall – the study that informs eyewitness expert testimony and helps police improve the collection and preservation of critical evidence – is a “forensic” science. The nomenclature was important – in the jurisdiction where the

To use the Pennsylvania test, “[t]o qualify as an expert witness, a witness need only have a reasonable pretension to specialized knowledge, on a subject for which expert
Do mask-wearing witnesses deprive criminal defendants of their right of Confrontation? Does impairing the ability of jurors and lawyers to fully assess ‘demeanor’ result in less reliable trials? Can jury selection be fair of prospective jurors’ faces are covered? Or is this all a Shakespearean “much ado about nothing” because we – the great majority
Does science support a firearms and toolmark expert from saying anything more than that “the firearm may have fired the recovered casing…? Not ‘it came from this gun and no other,’ or ‘casings from the crime scene and from test fires of the suspect’s gun match,’ but a much more calibrated and restricted conclusion, evidence that is
We live in a time where every action we take, every premise we rely on, warrants scrutiny through the prisms of race and implicit bias. This reckoning, long overdue for too many individuals and institutions, was brought about by the murder by police of George Floyd and the consequent outpouring of grief, rage and commitment.
The landmark holding Crawford v. Washington, now sixteen years old, changed the framework for challenging hearsay offered against the accused in a criminal case – if the hearsay was “testimonial” in nature it is admissible only under one of two conditions: The declarant will ultimately appear at trial and thus be subject to cross-examination regarding
