Now we do disagree if you feel that one should NEVER give first aid to an attacker. But, of course, that's up to each person. We could envision a scenario where the attacker is down, bleeding from a wound he can't stanch by hmself, and he begs for your help...with an open 911 line. You refuse. A possible outcome:
"Ladies and gentlemen of the jury, we have heard expert medical testimony that the deceased victim [that is, the attacker] could have, despite the massive firepower viciously unleashed at him by the defendant [the defender], could have survived, if the defendant had bothered to grab the towel lying 3 feet away and simply applied direct pressure to the wound. But he chose instead to let the semi-conscious, helpless, troubled [mentally disturbed and/or chronically criminal] church-going [his mom confirms] youth [under, say, 30--he looked younger at his funeral] bleed to death while he [prosecutor points finger at defendant] cruelly watched, and coldly listened to his pleas for help. [Prosecutor again turns on 911 tape] "Please, help me. God, I don't want to die. Please. I'm sorry. Oh, God, I'm dying. Help, please, help. [Sobs, then after a while, quietly] Momma..." [then silence. Prosecutor turns tape off, again points at defendant] What kind of monster do we have here, ladies and gentlemen?"
Ahem. Would I actually give aid? Maybe, maybe not: depends on the circumstances. What I mean is that I would not preclude that possibility, simply because I was attacked. And if I chose not to give aid, I would have articulable reasons why, having considered it, I chose not to do so in this particular case, rather than a general principle of "police don't do it, so I shouldn't," "it's only safe to render aid after he's dead," or the ever-popular "hey, shooting him is no problem--but if I try to help him, I could be in big trouble legally."
Just me.
