I'm sure you're aware, when someone is attempting to rob someone at gun point, they need to be eliminated or neutralized. By a law abiding citizen or cop, whoever has the first shot or opportunity.
Using a BB gun or whatever by the suspect is really meaningless from the defenders standpoint in these types of robbery incidents.
I agree, but lately the identity of the involved cop has been prominently featured. My question was as to whether the authorities were being prudent or protective, and I speculated that if protective, perhaps it was either a woman or a minority, or both, because that's the way it is these days.
