If the guy climbed in your car and assaulted you, you shoot him, you are clear. If he ran away and then decided to come back, can you shoot him while he menacingly coming toward you for a second time??
Has it been established that the perp turned around and came back at the cop?
Again - if the perp is not armed, was the cop not armed with a baton, a can of mace, a taser?
Given the state of the militarization of the police in this country - do we really want to give latitude to agents of the state, that at their discretion they can shoot to kill?
One law for us - a different set of "laws' for the state and their agents?
That seems to be the case at an ever-increasing rate. And to much applause.
