What can prevent tragedies like Charleena Lyles?

Bill Radke talks with former Seattle Police Chief Norm Stamper and state Representative Morgan Irwin, also a Seattle police officer, about the shooting of Charleena Lyles by Seattle police and what, if anything, could have been done to prevent it.

Irwin says the officers followed proper protocol during a tragic, isolated incident. Stamper says it points to larger problems of implicit bias and how police perceive danger on the job.
