I'm afraid I'm going to have to return Mr. X's favor and back him up.
Since we're talking rape here...
I've achieved surpise and have said rapist at gunpoint. Rape has stopped. Woman pulls a pencil out of her pocket and sticks it into the rapist's ear and scramble's it around. Hmm. Or, I slipped past the lookouts for the rapist and while I've got him at gunpoint, the lookout (trying to redeem his honor) slips up behind me and cuts my throat. I'm dead, and the woman gets raped some more. Now throw this into the twist. Homosexual rape. I live in a city with a significant gay population, so I now see two guys rolling around on the ground. And since homosexual rape tends to also be a gang rape, I'm now outnumbered. Back to the scrambling of the brain by the victim, or me getting my throat cut.
This is what I will do...Find a pay phone and call the police. I do my family no good whatsoever in the hospital, jail, bankrupcy, or the morgue. How can I protect my family from jail? How can I provide for my family when I'm bankrupt? I have to be prepared to spend money I do not have to defend myself in court and the following civil lawsuit when I end up defending myself by shooting!!! Why should I make it easier for a court system to jail, or bankrupt me because of my goodwill towards man? This all presumes that I didn't end up in the emergency room with, and have to pay off, that bill for the rest of my life. This also presumes that I didn't end up with a crippling injury and it's fallout (rehab, will I be able to work again, will I be a burden to my family, etc.). But most importantly, this presumes I was RIGHT in my assesment of the situation that I knew nothing about when I walked up on it. All of the above problems are compounded to a degree I can't even calculate if I was WRONG. And to bring this full circle, not one second of getting physically involved in the imagined event does anything to help myself or my family.
If people are not willing to take even the simplest measures to protect themselves, why should they count on someone else to save them.
Let's change our tack a bit here. Let's take the baby falling off the raft and drowning example. No shooting, no maiming, nice and clean. You jump in, pull the baby out of the water, but you're too late the baby has drowned. Parents are the Ramsies(sp?), and decide to sue your keester off because you took the time to get your shoes off and and stash your wallet in them before you jumped in to do your duty to mankind. How does being broke (and worse, giving your money to the Ramsies) help your family? And before you start calling me a cold hearted ogre, I would've jumped in to save the kid.
But there's a big difference between saving a drowning child, helping someone after a car wreck, and shuckin' out your heater during the Quik Trip robbery. There are plenty of times to risk your life as you wander about your day (try driving in rush hours traffic), why increase the odds of another fatherless/motherless child by getting involved in a slapfight between a man and a woman at a gas station.
In the end, the grass eaters are on their own.
Please forgive any spelling mistakes.
