I am as pro gun and pro self defense as the next guy but I am also pro common sense. The guy was 72 for cripes sake.
I’ve seen at least one person use the argument that because the shooter didn’t know the age of the victim, it was okay to shoot him and claim self defense against a victim who was clearly no threat, because it could just as easily have turned out to be someone from a high crime segment of society. There’s no way the old man could have posed a threat in his condition, nor even presented the appearance of a threat. It doesn’t matter if the shooter knew his age or medical condition. What matters is that he had no fear for his life or safety. Being afraid of his own shadow doesn’t count.
