The police killed Dorner before he could kill more innocents so it sure applied in this case.
If that's the case then why, as noted elsewhere on the thread, did the live-TV interviews of residents have them expressing relief, not that Dorner was dead, but that the police wouldn't hurt them?
Yet he didn't kill the couple in the cabin.
He didn't kill the guy whose truck he stole.
He potentially could have escaped had he, and he took the risk of them escaping or talking after he told them to walk away.
Not saying innocents couldn't have been killed by him in the future, but I do note that the only civilians not directly connected to the police who were injured and/or put in mortal peril were a couple hispanic ladies delivering newspapers and a surfer dude.
And it wasn't Dorner that shot them from behind with no warning, or t-boned a truck and filled it with lead.
