I think what you're saying is that the person getting stolen from has a duty to surrender their property to avoid escalating. That sounds absurd to me? The person doing the stealing is the one escalating as the natural state is the original owner keeping possession of their property. "Give me your wallet." "No." -- What happens next and who is the one escalating?

I doubt a thief would stick around for the cops to arrive. And I do think everyone knows you don't pull a gun until you're ready to fire it to neutralize a threat. (A truck is probably not a theat unless it's trying to run you over.)

That’s a mugging you’re describing. There’s an implicit threat of violence in being confronted by someone who demands your property, and drawing a weapon would likely be seen as justified.

Retail theft—someone grabbing stuff and fleeing the store—is a different deal. If you blocked the person from leaving and they threatened you, again, you might be able to justify drawing a weapon. But threatening deadly force against someone who’s running away isn’t the same situation.

As you said, you don’t draw a gun unless you’re willing to use it. If I were a store customer or employee, I’d be more worried about armed hero-types overreacting and possibly killing me, rather than someone stealing stuff and trying to escape.
