If her children are in the house, then it makes sense to run back to the house.
... if they were in (immanent) danger, yes (and the article didn't say... I've personally known abusers that never touched a kid, for what little that's worth. And gods know that makes them no less of scum.), but that wouldn't have been covered by SYG stuff. Otherwise th'law holds (so far as I'm aware) that other venues (like calling the cops, ferex) must be attempted before lethal force is pursued (which the court decided was). Blazes if the article provides enough information to know if they were. About all we know -- and even that, not from the article itself -- is that the woman was sentenced for attempted murder. Not stuff related to self-defense, or issues related to warning shots. Maybe the woman chose was the right action to take. Couldn't say, given the information provided.
S'like... yeah, if the kids are in danger, you pull the gun and do what you have to. If they aren't, you don't -- a gun does not come out unless there is immanent and immediate danger, period. I've no clue if the kids were in danger, and apparently (for what it's worth) the court decided they weren't (or at least her lawyer decided not to attempt that angle).
I'm also not about to accept that we should expect her to carefully reason through the legal implications of her actions[...]
Ignorance is kinda' no excuse for breaking the law, et al. If you're a gun owner, you are legally (and, frankly, ethically) obligated to know and hold yourself to the laws related thereof at pretty much all times -- so yeah, reasoning through the legal implications of her actions is part of the (big damn) responsibilities of gun ownership. There's absolutely
zero excuse to treat those things cavalierly or without due consideration. Situation can mitigate penalties*, but not the wrongness of the action.
I couldn't say, given the information, whether her action
was wrong, but the court decided it was and the information I'm currently aware of provides the
possibility.
*And part of the problem in this case is the woman ran into the minimum penalty for attempted murder, thus meaning mitigating circumstances couldn't be considered in regards to sentencing. Mandatory sentencing is utter and complete bullshit, yes.
As for whether or not you should pull a gun and then not try to kill somebody with it... If that's how the law works, I have to say the law is wrong. It's a better deterrent when it is pointed at somebody than when it isn't. You shouldn't get it out if you're unwilling to kill somebody with it, but you shouldn't be obligated to try and kill the instant you draw.
You aren't (note warning, etc.). Fairly certain that not providing warning can itself be grounds for legal repercussion in some situations.
