I don't think I can ever really answer the hypothetical case "do I have the clean go-ahead on squeezing the trigger" for things that fall in a grey area (which I think #2 does). But the question I'd be asking myself is a) are they really just going to put me on the chain-gang, or am I actually headed for the tree? b) do I have a chance of getting out of this later, and possibly getting the bastards punished for their ill-deeds, or is this my last shot at freedom? and c) if I defend myself now, do I have a higher chance of being killed than if I try to get out of this imposed bondage later?

(That last one is pragmatic as well as moral.)
