I had not heard of this incident until today. Found this where there was some basic info on it. http://heavy.com/news/2015/07/ray-tensing-samuel-dubose-criminal-record-cincinnati-police-shooting-victim-cop/
During the struggle, the car started to roll forward and Tensing was knocked to the ground. Upon recovering, Tensing fired a single shot into Dubose’s head, killing him, police said.IMHO, nothing will get you killed faster than attempting to leave and drive away during a traffic stop.
