Research shows our perceptions about officer-involved shootings often vary dramatically from their reality. Michael Scott, a police officer turned UW-Madison clinical associate professor of law who co-authored a book on police-involved shootings, recommended a video put together this year by the Lane County (Ore.) District Attorney?s Office that suggests officers have far less time and control than we might think in deadly force situations, which make up a tiny fraction of the 1 percent of police calls that involve the use of any force at all.
