I am not a lawyer. So everything I say could be wrong and every state is different but generally I think there’s a five point test for claims of self defense: Avoidance, Innocence, Imminence, Proportionality, and Reasonableness.
Avoidance is moot because I think this is Virginia and I think they have a no-retreat provision. Innocence is just that you didn’t willingly engage in a fight that got out of control. So that applies. Imminence applies because it happened in the moment. I just don’t see how Proportionality applies here. I just don’t see how holding a cell phone is proportional to a shooting. Emotionally I get it that the YouTuber is a major jerkwad and may have deserved a comeuppance. But I don’t think the jury followed the law.
