No, he didn’t. Review the case facts again.
Tell it the jury, not me.
12 people in his home state apparently unanimously agreed that he DID violate a law.
And, iF he stopped to reload his weapon before firing an additional, fatal, shot in to a wounded and incapacitated burglar, then I tend to agree with them. Once the threat has been ameliorated, continued self defense becomes assault and then murder.
