a) if somebody gives you the option of either being robbed/shot if you resist, or leaving the area, it's hard to make the case that the interaction is voluntary. this is easy to see if it's a guy on the street or a guy barging into your house making this proposition. I don't see how the situation is altered if the guy also claims to be a representative of the "goverment' other than revealing that in addition to being a criminal, he's also a lunatic. saying that by choosing to remain that you volunteer for this abuse is just away of obscuring the moral issue and blaming the victim. it's the distorted logic of abusers who want their aggression to be above question or reproach, but have your response to that abuse, regardless of what it is (be it leaving or staying), be a tacit approval of their behavior.
