The use of immediate lethal force by the police has been a hot topic in the wake of the many police-involved shooting deaths of African Americans. Tamir Rice was fatally shot within 10 seconds after Cleveland police arrived on the scene. The 12-year-old boy was playing with a toy gun at the time. And Laquan McDonald was shot 16 times by a Chicago police officer as video shows the teen, with a knife in his hand, walked away from officers. Are cops surveying a scene first to see if there’s a less violent resolution, or are they taking control of all situations by any means necessary? Is risk unacceptable? Those are some issues raised by Slate’s Jamelle Bouie. Bouie and Joseph Moseley, a retired Chicago sergeant, discuss law enforcement officers and risk. (Flickr/Can Pac Swire)
