Both. "Some people" would try to stop a fleeing suspect, let's say a shoplifter for example, by stepping in front of the car and ordering them to stop, maybe or maybe not at gun point. If the subject didn't stop, the officer would shoot, justifying the use of force with the logic, "I was in fear for my life.....BECAUSE HE WAS TRYING TO RUN ME OVER." On the surface, it looks and sounds legit, ie the suspect WAS driving a deadly weapon directly AT the officer, so it was reasonable for the officer to fear imminent death or great bodily harm....BUT the officer CAUSED the danger by positioning himself in front of the car. Our GOs now explicitly prohibit placing your body or any part thereof in the path of a moving vehicle with the intention of "stopping" it, AND we are explicitly prohibited from shooting at or into a vehicle, when the vehicle IS the only weapon and it would be "more prudent" to simply get out of the way.
