The truth gives us context the law does not allow for. These people were not innocent protestors merely using their first amendment rights, they were bad faith actors. Psychopaths using the opportunities of the day to cause havoc, I think that's pertinent context to the situation especially in dealing with moral as opposed to legal culpability.How is it being dismissed? If it's self-defense it's self-defense even if they were previously the curers of cancer and possessed every virtue under the Sun, and if it isn't self-defense they were unjustly murdered even if they were Hitler triplets (Godwin), so either way it seems irrelevant. I don't think it's dismissed as much as it is irrelevant to everything.
If your aunt had balls, she'd be your uncle. Kyle wasn't an active shooter, and he knew that because he was running with him/behind him. He interviewed him, he wasn't shooting into the crowd. Kyle only shot those who were intent on murdering him. That's what self defense law protects, that's why he was acquitted.If you drew your weapon in response to an active shooter who had already killed two people, would the shooter be justified in shooting you?
If I drew my gun on a person who was retreating and killed them, I would be rightly charged with and convicted of murder, regardless of what I thought about the status of the legality of their other shootings. If I drew my gun on someone who was in the midst of being attacked by a mob and they were armed I would have every expectation of being shot.
