No. . .you just pull your own weapon and shoot them first!
But then again, why not just give in and die on your knees as opposed to dieing on your feet, and given the murderer in this case was very trigger happy, I'd say she was already dead before the robbery began.
And if you live in New York and don't own a gun, you should point your finger at them and shoot?! Or just shut up and let them rob you. I choose to shut up and let them rob me.
