Is that what the officer claimed in his report? If so why would the officer lie and state he was being drug by the suspect/vehicle when he was clearly not being drug by the suspect or vehicle.
Officer Tensing may not have lied. I don't know if there is a universal definition of "drag" in this kind of circumstance. Officer Tensing would have had to make the decision to shoot before he was pulled off of his feet and his body was pulled along the ground since any aimed fire would have been impossible at that point. Officer Tensing could then have been run over by the rear tire or abraded to death by the road. Having his hand hypothetically grabbed by the driver of a car in gear with its engine on with the driver showing a clear intent to illegally drive away meets my definition of "drag" regardless of the speed of forward movement.
