I had a LEO pal of mine tell me that you shoot whenever you feel like your life is threatened, whether the perp is inside or out. He went on to add that it's much easier to get a jury to believe that your life was in danger when the other guy isn't alive to say otherwise. I hope I never have to put 12 people in that situation.
One of our courtesy officers told me the same thing make sure you kill them if you have to shoot or theyll be in the courtroom saying they was accidentally at the wrong house their cousin musta gave bad directions and they got shot while politely knocking on the door.
