When a Madison police officer fatally shot Corey Ruiz on July 22, his death sparked outrage — and questions.
Among them: Why was Ruiz killed, and what kind of training or rules could have prevented his death?
Ion Meyn, an associate professor at the University of Wisconsin Law School, has studied exactly that. For a 2021 paper, he and his team interviewed police officers across the country and watched dozens of training videos to understand how police think about use of force and what guidelines they learn — even as departments argue that such situations can never be governed by hard and fast rules.
