Wild, thanks for starting this poll and discussion. For some of us, the issue of when it's OK to take a human life is, or should be,
the central question of ethics. 'Bout time we talked about it a bit, without all the posturing which seems to be brought out by particular cases.
rantingredneck nailed it:
Since the killing of others is frowned upon when it can be avoided, then I would say we definitely have a moral as well as legal duty to retreat if retreat can be accomplished safely. The duty ends when "safely" ends.
If I'm in danger from an attacker, I'll always retreat
if I can do so safely. If others are in danger, I'll do the same... with the intention of calling 911, being a good witness, and all that good stuff, if, again, I can do so safely. As has been pointed out
ad nauseum in other threads, it's too easy to make a mistake about what's happening in a situation involving other people, and the consequences of being wrong can be huge; so I'm very unlikely to intervene.
Two points haven't been much addressed here: what constitutes retreating, and the difference between protecting life and protecting stuff.
As to the first, "retreating" seems pretty situational to me. If I'm at home and someone breaks in, it means I'm either out the other door, or I'm headed upstairs to the bedroom, exactly as 5whiskey described:
My version of a home invasion would include me holing up in the bedroom, firing warning shots in the deck before perp ever reached the bedroom, and yelling commands to leave. That's as safe for both parties as I know how to make it. If perp continues on to bedroom after all that, then he's probably after me personally and not any "stuff".
Well, actually, I'd call 911 right quick, and I'd pass on the warning shots, but otherwise -- yup, that's me, too. So in this case, "retreat" means to me not to confront an intruder, but to retreat to and hole up in a defensible spot, on the principle that he can take whatever's downstairs, but if he comes upstairs, knowing I'm there, and armed, he is after me and I will defend myself.
Anywhere else, my first choice is always going to be to get out the back door, or drive away -- whatever gets me out of the situation. I'll be glad to throw a mugger my wallet, if that's what it takes to get away from him.
I don't ever want to take a life over money or possessions -- I'll defend my person if I have to, but for me, anyone's life, even a criminal's, has more value than material objects.
If I'm pursued, I'll do whatever I can to discourage a pursuer: go somewhere where there are other people if possible, etc. Back when I was in college, I was driving back from a camping trip on an empty highway when six guys in an old car tried force me to stop -- which seemed like a really bad idea.
My "retreating" in that situation took the form of flooring it, passing them (my old Chevy was a lot quicker than it looked), getting chased by them -- and after a mile or two, snugging up to the bumper of the first car I caught up to, at which point the six guys drove off, with lots of obscene gestures, etc... If I'd had a gun in the car, I might've shown it to them, but I'm not sure that would have improved the outcome. Getting the hell away and finding some witnesses seemed like the best option then, and it still seems like the right thing to have done.
So here's a question : Does "retreating" mean that you do whatever you'd do if you were unarmed, only knowing that you have a backup if push comes to shove? Or does it mean something different if you're armed: backing off and giving an attacker a chance not to come after you but intending to shoot if he does? In the case of a home invasion, I guess I'd say it means the latter, but out in the world, I'm not so sure.
