So what you are telling me is that shooting someone with intent to kill is sometimes not murder, so defining "murder" as killing someone intentionally is not accurate.
Exactly my point.
Yes. I didn’t think people would have such a hard time understanding that there are circumstances which justify intentionally killing someone
That was the whole basis of her defense.
My point was that, in Texas at least, if you intentionally kill someone and are convicted, you are convicted of murder. There is no other choice. You can not get manslaughter if you did it intentionally. And she testified she did it intentionally. She was going for an all or nothing defense.
Of course if what you did was justifiable (self defense, protecting your property or others property, etc,) then you are not guilty in the first place.
