[Lurking Libertarian]

There are three very different defenses presented here ... "Stand your Ground", self-defense and accidental. Perhaps Thompson's lawyer is throwing all sorts of mud at the wall hoping one of them sticks. But the author didn't note the distinction of each of the defenses.

Not really three; "stand your ground" is a subset of self-defense.

The lawyer is arguing stand your ground/ self-defense; the prosecutor pointed out that earlier (apparently before she got the lawyer), she claimed accident, which is inconsistent with self-defense. (If you kill someone in self-defense, it's intentional, albeit justified; there is no such thing as accidental self-defense.)

She would have killed him in self defense if she hadn’t already killed him by accident? Or was it the other way around? I’m so confused.
