Donald J. Van Meter, Ph.D.
I am a qualified expert witness specializing in police use of lethal force, with a focus on human performance, decision‑making, and performance management science under high‑threat conditions. My expertise is grounded in more than a decade of hands‑on instructional experience, during which I taught and evaluated law enforcement officers on lethal‑force decision‑making, threat assessment, and performance under physiological and cognitive stress.
My work centers on the human factors that influence officer behavior in critical incidents, including perception, reaction time, attentional narrowing, stress‑induced performance degradation, and the interaction between training, policy, and real‑world application. I have extensive experience translating complex human performance science into practical, operationally relevant analyses understandable to attorneys, judges, and juries.
Currently, I serve as a pretrial analyst and consultant in cases involving law enforcement use-of-force. In this role, I conduct independent pretrial case reviews, evaluating incident facts, video evidence, training records, policies, and officer actions through the lens of established human performance and police training principles. I assist defense counsel and law enforcement defendants by identifying scientifically supportable explanations for officer decision‑making, highlighting relevant performance factors, and advising on defense strategy development grounded in objective analysis rather than hindsight bias.
My work is focused on educating the trier of fact about what trained officers are reasonably capable of perceiving, processing, and executing during rapidly evolving lethal‑force encounters, and on ensuring that officer actions are assessed within the realistic constraints of human performance rather than idealized or retrospective standards.
