Was Bernhard Goetz justified in shooting at his four assailants on the NY subway car? If he had had something less discriminating (hand grenade), would he have been justified in using that?
I'm sorry, we are confining our discussion to the Second Amendment. And since Chinese citizens are not protected under this amendment, this is aside the point.
Was Bernhard Goetz justified in shooting at his four assailants on the NY subway car?
I believe he was, until such time as he stated "You don't look so bad, here, have another" and shot again. At that exact moment, he went from a person who a victim who was defending himself, to an assailant who was attacking incapacitated opponents.
If he had had something less discriminating (hand grenade), would he have been justified in using that?
No, because schrapnel from the grenade would have invariably injured other people on the car and people on the platform, not to mention himself.
