Breda has an especially good post up anent fighting back.
She links to several other posts by other bloggers that are also well worth reading. Personal encounters with, well, Evil.
I've seen that elephant my own self. Twice at least, back when I was unarmed and most unaware; I'd tell the tale but others have done so and better. The condensed version of the worst: I ran. Bad guy caught up. I threw a bag of groceries at him. He shot and missed, closed the few feet remaining, knocked me down and got my purse and the wad of cash I used to carry in lieu of credit cards. Meanwhile back at the car, my ex was being divested of wallet and watch by the other three goblins.
Next time? I don't want a next time. My adrenaline reactions are harsh; my decision-making process becomes very rapid and very short-term. My hope and goal is to face it on my feet, resisting.
Why would anyone do anything else?
