I'm responding to this after having already responded to Captzapheart below, and what I say there, I repeat here. Kyle made a choice to be in that location. I disagree with that choice. One element of the choice to be there was being armed. Using a logic framework to describe this: If go there -> carry firearm for self-defense. That logic makes sense. But the logic within that decision is after the fact of the earlier question of whether it is productive for him to go there in the first place. He wouldn't have been a person of interest if he hadn't been there. Going into violent situations opens the possibility for violence. The passion of some carries them there, but the actual ensuing violence is never as noble as the image they had of it in their minds when they made the decision to attend the event.
