Theoretically, if you see someone who a reasonable person would believe is being threatened to the point of death or grave bodily injury I understand you have the right to defend them. But doesn't that go against the law saying you have a legal obligation to retreat? Or does that go out the window if the victim is being held against their will and doesn't have the option to retreat? (Presumably in non stand your ground states)
I tried to word this as specifically as possible to make the other questions not take over the thread.
