some have put forth that the presence of a gun in the hand of a bad guy does not rise to the level of enough threat to warrant a response and I'm having a hard time figuring out what WOULD be, if that isn't.
Ahhh, I see. No, I don't agree that it doesn't
warrant (in other words, justify) a violent response. My line of thinking is aimed at how to determine whether that violent response will make things turn out better or worse. I doubt (even outside of Texas!
) most DAs and juries would convict you for manslaughter if you killed a robber when he drew his pistol in a jewelry store, just about regardless of whether he intended to use it. In fact, I'm pretty sure I've read of justifiable homicides wherein the robber had an unloaded gun or even a fake one.
But the opportunity to draw and fire your own weapon without immediately dying may not clearly present itself. And setting off a gunfight in which several people are killed is a very negative outcome, too, especially if the immediate social cues did not lead you to believe that their (and/or your) deaths were otherwise imminent.
The idea that I should trust a bad guy not to shoot, and that I should not respond if i am able to just doesn't make sense to me.
No. But each choice involves risks that the person involved will have to evaluate in the moment.
Deciding that someone holding a gun on you may be trusted not to kill you is no more reasonable than deciding that, simply because he's holding a gun on you (or others) that he WILL kill you (or them).
There are two possible working theories in that moment:
1) "This guy will walk out of here with his sack of loot, without firing a shot, if I just bide my time and no-one does anything to trigger violence."
2) "This guy is going to kill people before he leaves."
Several things should inform your evaluation:
1) What is the guy saying and doing? What's his mental state? What cues do you have about him personally that indicate which way he's going?
2) Most armed robbers don't shoot or kill anyone because there's no money or security benefit in it and it comes with some negatives.
Several things could inform you decision:
1) I do/don't have an unobserved moment to draw my gun.
2) I do/don't have a moment of distraction to aim and fire my gun.
3) I do/don't have a clear shot at one or more robbers without killing the wrong person; and,
4) Events are/aren't rapidly escalating to immediate bloodshed.
Number 4 there has the power to reduce or even nullify many of the other 3.
I'm looking at this the same way I believe most hostage negotiators do. The best result for all the innocents involved is to finish the scene without any shots fired. We can (try to) end this with violence at any minute, but the stakes for the lives of the innocents (including yourself, here) are very grave. (Ha! A pun! Shakespearean, no less!
) We can risk giving the bad guy the time to work things out to what he thinks is his advantage, and see if either things de-escalate, or things come to a crisis of violence. Be prepared for that violent crisis and act unhesitatingly if it does come.
