This police body-cam video shows Coeur d’Alene [Idaho] Police Officer Spencer Mortensen ordering Eric Byron Johnston to drop two knives before shooting him. [Click here for spokesman.com’s story.] Yes, the Tueller Drill tells us that there’s precious little time to shoot a quick-moving assailant. But Mr. Johnston doesn’t appear to be rushing Officer Mortensen. More to the point, why didn’t the officer retreat? Couldn’t the cop have backed out and waited for some non-lethal resolution? Nope. As our commentators point out below, retreating would have exposed the officer to additional danger. Suicide by cop? Mentally unhinged? Or just plain dumb? Either way, our condolences to both the family of the perp and the policeman who ended his life.
