I wasn’t saying it was ok to shoot this guy. But a large guy starts harassing you at the mall, doesn’t listen to you when you ask him to stop, advances on you when you try to leave, could very well have had a gun as well (since this is the US), and you think punching him in the face would have worked? In hindsight, maybe. All that to say is I feel sympathy for this guy even though he escalated it beyond what was necessary.
