Of course I would not immediately shoot someone standing at my door. but my point is, I would not go to the door at all unprepared. Everyone who knows me, includes family, knows to stand in front of my window so I can see them. Window on the front before steps to my porch and front door. I also have two indoor dogs, and a Catahoula outside. If anyone approaches my house thru the woods, he is all over it barking. That includes family. I know my dogs reactions and yes, if I am not comfortable with the situation, I would fire. Maybe a warning shot first, but I would definitely shoot.
