No other lawyer in his right mind would either. Morality aside, there's no money in it.
Your daughter being attacked, and some young adult male who is getting his head kicked in because he deserves it (as in the example offered in the thread), are two completely different scenarios that would require two completely different evaluations.
With that said, it would be prudent to stay out of any and all situations that do not require your intervention.
In my 26 years of making a livelihood and supporting my family by representing injured people in civil law suits, I've never taken a case where a perpetrator sued a victim for shooting him. I wouldn't think of it. No other lawyer in his right mind would either. Morality aside, there's no money in it.
Just because a female is getting "attacked" doesn't automatically mean that the female is the victim. Plenty of female drug addicts and gang bangers who can be just as dangerous as a male. I wouldn't just stand there, but my intervention would likely be some yelling while calling 911. There is no way to know if the female is really a victim, or maybe an offender who just tried to rob the wrong person, or take her child where a court granted custody to someone else, etc.. If it doesn't involve family or friends, the limits of my intervention are calling the cops, maybe yelling from afar. I can't take care of my family if I'm in jail for shooting a guy who is trying to keep his drug addicted ex from taking the kids, or from some addict who just tried to rob the guy.
There's a certain comfort in knowing that you have a lawyer who will advise you before you make a formal statement. I know I was real happy to have an experienced attorney I could call immediately. After a serious event is no time to start lawyer shopping, and the cavalier "I'll just stay the night in jail" crowd, well, after going through something as nerve wracking as killing another human being I think you'll find you'd be much more comfortable around friends and family than a bunch of random arrestees. I forget where I read it it, but surviving the fatal encounter starts your second survival challenge, dealing with the aftermath both legally and emotionally.
The "don't say anything" crowd will get you screwed. Give a brief rundown of what happened. You don't have to go into great detail, but where people were standing, where they came from, etc can all assist in locating and preserving evidence that is going to help prove your side of events. Ask the various liquor store clerks that shot robbers in Indy last year. If its a good shoot, its pretty simple to explain it and go home. The trick is you better know up front what's a good shoot and what isn't, and if you don't know that then leave your gun at home in a locked container until you do.
To add something you didn't ask, if you have a significant amount of assets that a civil lawsuit could wipe out, you may want to take a look at an umbrella insurance policy. For roughly $200 a year you can get $2m in liability coverage. Its one of those things that not everyone needs, but can save a lifetime of hard work if you do.
