I think you are projecting when the facts are not clear. Cops are trained, apparently, to learn how to diffuse, not accelerate situations. That didn't happen here apparently.

While unarmed has no bearing on threat levels, shooting one in the back, numerous times, and then leaving the dead body in the street, uncovered, for 15 hours, is problematic if those reports are true.

Having been a cop leaving a body at the scene is not unusual. A thorough investigation has to be made and that takes time.
