Dane County District Attorney Ismael Ozanne announced Tuesday that a white police officer who shot and killed an unarmed black 19-year-old in Madison, Wisc., used lawful force and will not face criminal charges. This incident is one in a series of deadly encounters between police officers and African-American men across the country.
Cheryl Dorsey, a retired sergeant who spent 20 years with the Los Angeles Police Department, is the author of the book "Black & Blue: The Creation of a Manifesto." She spoke with Here & Now's Robin Young about the use of deadly force by some police officers and what she thinks might stop it from happening so frequently.
