When police officers shoot people under questionable circumstances, Dr. Lewinski is often there to defend their actions.

His conclusions are consistent: The officer acted appropriately, even when shooting an unarmed person. Even when shooting someone in the back. Even when witness testimony, forensic evidence or video footage contradicts the officer’s story.

However, Lisa Fournier, a Washington State University professor and an American Journal of Psychology editor, said Dr. Lewinski’s past research on the dynamics of police shootings lacked basic elements of legitimate research, such as control groups, and drew conclusions that were unsupported by the data.

“In summary, this study is invalid and unreliable,” she wrote in court documents in 2012. “In my opinion, this study questions the ability of Mr. Lewinski to apply relevant and reliable data to answer a question or support an argument.”
